Answer 1

Answer:

Variable x = $2.39 ⇒ price of 1 pound of cashews

Variable y = $1.79 ⇒ price of 1 pound of peanuts

Step-by-step explanation:

Assume that the price of each pound of cashews is $x and the price of each pound of peanuts is $y

∵ The price of 1 pound of cashews = x

∵ The price of 1 pound of peanuts = y

∵ 5 pounds of cashews and 8 pounds of peanuts cost $26.27

∴ 5x + 8y = 26.27 ⇒ (1)

∵ 7 pounds of cashews and 4 pounds of peanuts cost $23.89

∴ 7x + 4y = 23.89 ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (2) by -2 to make the coefficients of y equal

   in values and different in signs

∵ -2(7x) + -2(4y) = -2(23.89)

∴ -14x - 8y = -47.78 ⇒ (3)

→ Add equations (1) and (3) to eliminate y

∵ (5x + -14x) + (8y + - 8y) = (26.27 + -47.78)

∴ -9x = -21.51

→ Divide both sides by -9 to find x

∴ x = 2.39

→ Substitute x in equation (1) or (2) to find y

∵ 5(2.39) + 8y = 26.27

∴ 11.95 + 8y = 26.27

→ Subtract 11.95 from both sides

∴ 8y = 14.32

→ Divide both sides by 8 to find y

∴ y = 1.79

∴ The price of 1 pound of cashews is $2.39

∴ The price of 1 pound of peanuts is $1.79

Two parallel lines are crossed by a traversal. What is the value of h?
h=60
h=80
h=100
h=120

Answers

Answer:

h=60

Step-by-step explanation:

The angle that is 120 degrees and the angle that is h degrees are called same side interior angles

Same side interior angles are supplementary, meaning that they add to 180 degrees

To find h we can use Measures addition postulate to find the unknown value h

h+120=180

h=60

Kyra observed that 85% of the students at a library liked reading mystery stories. If 30 students at the library did not like reading mystery stories, the number of students at the library who liked mystery stories was _____. (only put numeric values, no other symbols)​

Answers

Answer:

The first thing we must do is find the percentage of students who do not like to read mystery stories.

We have then:

Then, to find the number of students who like to read mystery stories, we can make the following rule of three:

15% ----------------> 30 students

85% ----------------> x

From here, we clear the value of x.

We have then:

the number of students at the library who liked mystery stories was 170

Which equation represents a line that is perpendicular to y=x?

A.

y=2x

B.

y=−x+6

C.

y=−2x

D.

y=x+1

Answers

Answer:

B

Step-by-step explanation:

The general equation of a straight line can be represented as;

y = mx + b

where m is slope

If two lines are perpendicular, the product of their slopes will be -1

So since the slope of the first line is 1, then the slope of the second line will be -1

Out of all the options, only have its slope as -1 and this y = -x + 6 and this is our answer

Two containers P and Q are filled with different amounts of water. Each container has a small hole. The graph shows the amount of water, V milliliters, left in each container after x minutes.

Explain what the y-intercept means in this scenario.

Answers

Answer:

Step-by-step explanation:

Equation of the line for container O and container P will be in the form of,

y = mx + b

Here m = slope of the line = Change in amount of water per minute

b = y-intercept

From the graph attached,

y-intercept 'b' represents the initial amount of water in the container.

For container O, initial amount of water in the container is 1000 mL.

Similarly, initial amount in the container is 900 mL.

pls help Solve for m. -7+4m+10=15-2m

Answers

Answer:

m=2

Step-by-step explanation:

Answer:

[tex]m=2[/tex]

Step-by-step explanation:

[tex]-7+4m+10=15-2m[/tex]

Isolate the variable m. Combine like terms (-7+10):

[tex]3+4m=15-2m[/tex]

Subtract 3 from both sides (inverse operations):

[tex]3-3+4m=15-3-2m\\\\4m=12-2m[/tex]

Add 2m to both sides (inverse operations):

[tex]4m+2m=12-2m+2m\\\\6m=12[/tex]

Divide both sides by 6 to isolate m (inverse operations):

[tex]\frac{6m}{6} =\frac{12}{6} \\\\m=2[/tex]

Since this cannot be further simplified, m is equal to 2.
