Can someone explain to me how I can eliminate one of the variables to solve this equation for one of the variables?

Can Someone Explain To Me How I Can Eliminate One Of The Variables To Solve This Equation For One Of

Answers

Answer 1

Answer:

In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Answer 2

Answer:

x = 1 and y = 4

Step-by-step explanation:

Multiply the top equation by 7 on both sides, and then cancel it out:

7(5x + y) = 7(9)

35x + 7y = 63

Now use this equation to cancel out -7y on the second equation:

35x + 7y = 63

10x - 7y = -18

45x = 45

x = 1

Now that we have our x-value, we can plug it into one of our two original equations:

5(1) + y = 9

y = 4

Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
5 cookies
1.5 cookies
50 cookies
48 cookies

Answers

Answer:

just do this 24.76min. 23.24 then see what u have got for

Answer:

c - 23.24 = 24.76 (the first option)

48 cookies

Explanation:

Profit is equal to revenue(amount made) minus costs, or r - cost = p. The revenue is 1*cookies sold, or c. So, c - 23.24 = 24.76.

Solving is relatively simple,

c - 23.24 = 24.76

c = 48 (add 23.34 to both sides)

(c) Suppose a car is traveling northeast on King Avenue and turns left onto 4th Street. What is the measure of the angle created by the car's turning? Explain your answer.

Pls work it out for me I'm VERY confused.

Answers

Answer:

c.The measure of the angle created by the car's turning is 105°

Step-by-step explanation:

Suppose a car is traveling east on 4th Street and turns onto King Avenue heading northeast. What is the measure of the angle created by the car's turning? Explain your answer.

180°-70°= 110° ✓

This person  would be driving 110° degrees. ✓

So, what we would do it do 180° subtracted by 70. We need to find how much he turns onto King Avenue heading northeast. So we do 180° because that would be considered a full half turn, so 180° subtracted by 70 and that would give you . . .

180° - 70° =

(Part 2)

Your question states:

Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.

This may be a little tricky on this side. These side's are coherent. As we know now that the angel on (King Ave.)  was 110°, we would say the on the (3rd angel through King Ave.) that angel as well would be 110° because that is the angel on top. This would mean that they would be the same. But the thing is, we are finding what is the angel when the car is traveling southwest on King Avenue and turns left onto 3rd Street. This angel would be 70° degrees because as we do 70° + 70° + 110° + 110° = 360°.

This is how we would know that this would be that angel going into (3rd Ave).

My steps: 360° - 110° - 110° = 140°.

140° ÷ 2 = ∡70° ✓

Your correct answer would be

Step #3

Your question states:

Suppose a car is traveling northeast on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.

Your correct answer would equal 110°. ✓

My steps:

360° - 75° - 75° = 210°

210° ÷ 2 = 105° ✓

Your correct answer would be

What are the answers to these questions??

Answers

Answer:

1) c and d

2) 44

3) a and c

1: if 96 is the 100% price and 32% is what you need to find, it is 32 out of 100. 0.32 is the same, as well as 32/100.

2: if you divide the shape into different pieces, i find it easier to find the area. 9 x 3 = 27. 4 x 2= 8. 3 x 3 = 9. 27+8+9=44.

3:  the ratio 8:20 can be simplified down to 2:5 which makes A true. if the ratio is originally blue:red, then for c, 10:4 is the same as 4:10 since it states red to blue instead of blue to red, meaning c is also true.

Answer:

1. C and D.

2. 34

3. A and C

Step-by-step explanation:

1. All you have to do is solve each equation in order to see which ones are equal to the same answer

A. 32 * 96 = 3072

B. 3.2 * 96 = 307.2

C. 0.32 * 96 = 30.72

D. 32/100 * 96 = 30.72

Both C and D have the same answer.

2. Add up all the sides

9+6+5+4+3+3+2+2= 34

3. Look at each answer carefully.

A. There are 2 blue cubes for every 5 red cubes. True

B. When the game has 56 cubes in all, there are 40 red cubes. False

C. The ratio of red to blue cubes is 10:4. True

D. The ratio of all cubes to blue is 28:20. False

g÷ 5/8 =1
basically its asking what divided by 5/8 = 1

Answers

Answer:

5/8 divided by 5/8 = 1

Step-by-step explanation:

First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.

[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]

Now, multiply both sides by 5 to get rid of the fraction.

[tex]8g = 5[/tex]

divide both sides by 8

[tex]g = 5/8[/tex]

It’s asking you to what 5/8= 1 to do basically you have to multiply the 8 to both sides and then you probably will get your answer but I’m not to sure

Claire thinks that if she draws a parallelogram with 2 congruent sides, it must be a rhombus. Jacob thinks that she would need to draw a parallelogram with at least 3 congruent sides before she could be sure it was a rhombus. Who is correct, if anyone, and why?
Only Claire is correct, because if the figure is a parallelogram and 2 sides are congruent, it must have all 4 sides congruent.
Only Jacob is correct, because a parallelogram with 4 congruent sides must have 2 pairs of opposite sides that are congruent.
Both are correct because if a figure has at least 2 congruent sides, it must have 4 congruent sides.
Neither is correct because one would need to draw 4 congruent sides in order to be sure the figure was a rhombus.

Is C6H1206 an element or compound WILL GIVE BRAINLIEST plz help Civil Disobedience Part 1 Most people remember Gandhi and Dr. Martin Luther King, Jr. as reformers who practiced non-violent forms of protest and advocacy. Both effectively changed the popular opinion about emotional issues for their countries and brought in a wave of change that was long overdue. But the practice of non-violent protest, or civil disobedience, started long before either Gandhi or King. It began with a quiet, shy poet who is best known for writing a lot about a pond. Henry David Thoreau lived from 1817 until 1862, mainly in the area of Concord, Massachusetts. The issue that would tear the country apart in the 1860s had already begun dividing the nation. Thoreau was only 14 when Nat Turner led the slave rebellion in Virginia and was later hanged. In his late 20s, Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden. Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf. It was this experience that Thoreau wrote about in an essay called "Civil Disobedience." In this essay, he argued that being moral and just came before allegiance to government. He wrote If the machine of government is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law." He also felt that voting was not enough to ensure that the right thing be done. He wrote that "even voting for the right is doing nothing for it A wise man will not leave the right to the mercy of chance" He felt that one had a moral responsibility to resist unjust laws.
