Answer:
Step-by-step explanation:
1. 3x + 5 = 5x -9
2. 2x + 5 = 3x - 3
3. 3x + 2 = 5x - 16
Pls again answer equation questions find x, I can do this but I am so exhausted.
Answer:
1)7
2)8
3)9
Step-by-step explanation:
1)3x+5=5x-9
3x-5x=-9-5
-2x=-14
x=7
2)2x+5=3x-3
2x-3x=-3-5
-1x=-8
x=8
3)3x+2=5x-16
3x-5x=-16-2
-2x=-18
x=9
Hope I am correct and if I am not I will edit my answer
Answer:
1. x= 7
2. x= 8
3. x= 9
Step-by-step explanation:
1. 3x+5= 5x-9 2. 2x+5= 3x-3 3. 3x+2 = 5x-16
3x-5x= -9-5 2x-3x = -3-5 3x-5x = -16-2
-2x= -14 -x = -8 -2x = -18
x= -14/-2 x = -8/-1 x = -18/-2
x = 7 x = 8 x = 9

Which describes unit rates? Check all that apply.
-Nadia pays $30 for 2 baseball tickets.
-A certain type of sailboat travels at 7 nautical miles per hour.
-The cost of 3 hot chocolates is $2.
-A summer camp provides 3 meals for each camper.
Answer 2,4 are all described as unit rates a unit rate is anything that has per or each in it so a certain type of boat travels at 7 hours PER mile so we know question 2 is correct and 3 is a unit rate because it has each in it A summer camp provides 3 meals for EACH camper. That’s why the answer is 2 and 4

In a carnival game, there is a machine that will shuffle a deck of 50 cards numbered from 1 to 50 and then spit one card out. If the number on the card is odd, you win $15. If the number on the card is even, you win nothing. If you play the game, what is the expected payoff?
$___
Answer:
$7.50
Step-by-step explanation:
Since there is a 50% chance that the card is odd, the expected payoffs would be $15 * 50%=0.5*15=7.5. Hope this helps!
Why do you think you can prove congruency with SSS but not with AAA Property. Explain your answer with figures.
In AAA (Angle-Angle-Angle), triangles do not have the same size and only have 3 pairs of congruent angles.
In SSS (Side-Side-Side), if the three sides of one triangle are equal to the three sides of another triangle, the triangles are congruent.
write with explain.
Answer: The acute angle between diagonals is 50
Step-by-step explanation:
Red angle = 50 because An exterior angle of a triangle is equal to the sum of the opposite interior angles (pink angles).
Alternatively:
Green angle is 130 by sum of interior angles of a triangle.
Red angle is 50 by Adjacent angles
Sin485 positive acute angle
Solve for x. Assume that line which appear to be diameters are actual diameters.
Answer:
x = 8
Step-by-step explanation:
The angle above the 6x-8 = 180 -140 = 40
The angle on the opposite side is 40 degrees as well because they are vertical angles
6x-8 = 40 degrees
Add 8 to each side
6x= 48
Divide by 6
6x/6 = 48/6
x = 8

POR FA AYUDA URGENTEMENTE Dado los puntos A(-1;3) , B(2;5) y C(3;-1). Calcule 3(BA)VECTOR - 4 (CB)VECTOR
Answer:
the answer should be c
Step-by-step explanation:
Find the minimum value of C=x+3y
Answer:
c
Step-by-step explanation:
2x + 3y > 6 (1)
3x – 2y = 9 (2)
x + 5y = 20 (3)
From (1) and (2), we have:
(2x + 3y) - (3x - 2y) > 6 - 9
5y - x > -3 (4)
From (3) and (4), we have:
(x + 5y) - (5y - x) > 20 - (-3)
2x > 23
x > 12,5 (5)
From (3) and (5), we have:
x + 5y = 20 ⇔ 12,5 + 5y > 20
5y > 7,5
y > 1,5
So: C = 4x + 3y > 12,5 × 4 + 1,5 × 3 = 50 + 4,5 = 54,5
Conclusion: C > 54,5
In ΔJKL, the measure of ∠L=90°, KL = 6 feet, and JK = 7 feet. Find the measure of ∠K to the nearest tenth of a degree.
Answer:
40.6 degrees
Step-by-step explanation:
We know:
KL = 6
JK = 7
Angle L = 90 degrees
So JL is the hypotenuse, meaning we can find it with Pythagorean Theorem. This gets us :
[tex]6^{2}+7^{2} = c^{2}\\c =\sqrt{85}[/tex]
We can find angle K with the following equation:
[tex]sin(k) =\frac{opposite}{hypotenuse} = sin(k) = \frac{6}{\sqrt{85} } = k = arcsin ( \frac{6}{\sqrt{85} }) = 40.6[/tex]
Answer:
31
Step-by-step explanation:
\cos K = Adj/Hyp = 6/7
cosK= 7/ 6
K=\cos^{-1}(6/7)
K=cos −1 ( 6/7 )
K=31.0027≈31

Direct Variation: If y = 9, when x = -3, find x when y = -27. a.9 b.27 c.-27 d,-9
Answer:
a. 9
Step-by-step explanation:
[tex]k = \frac{9}{-3} = -3\\y = -3x\\-27 = -3x\\\frac{-27}{-3} = \frac{-3x}{-3} \\9 = x[/tex]
Answer:
a. 9
Step-by-step explanation:
because the orginal number was 9 and the newer one is -27 we can determine that y was multiplied by -3 so you would apply the same rule to -3 or x and you would get a product of 9 because two negatives equals a postive
