Answer:

x + 4y = 13

x = -4y + 13....now we sub this into the first equation

2x - 3y = -29

2(-4y + 13) - 3y = -29 <=====

-8y + 26 - 3y = -29

-11y + 26 = -29

-11y = -29 - 26

-11y = -55

y = 55/11

y = 5

x = -4y + 13

x = -4(5) + 13

x = -20 + 13

x = -7

Step-by-step explanation:

Answer:

A) 56/x=85/100

C) 56=(0.85)w

Step-by-step explanation:

Sonce 56/.85=65.88, we look for the two that have that answer.

A) 56/x=85/100

cross multiply 5600=85x

divide by 85

x=65.88 - YES

B) p=(0.85)56=47.6 - NO

C) 56=(0.85)w

Divide both sides by 0.85=65.88 - YES

D) x/56=85/100

100x=4760=47.6 - NO

PLEASE HELP!!!! WILL GIVE BRAINLEST
tiny-mole [99]

Answer:

31

Step-by-step explanation:

Since the two sides are equal, the two angles are equal

8x-1 = 5x+11

Subtract 5x from each side

8x-5x -1 = 5x-5x+11

3x-1 =11

Add 1 to each side

3x-1+1 =11+1

3x =12

Divide by 3

3x/3 =12/3

x =4

Now we can find WZY

5x+11

5(4)+11

20+11

What is the measure of angle C?<br><br> A 28°<br><br> B 62°<br><br> C 90°<br><br> D. 10°
Ray Of Light [21]

For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees. So, we have:

(5x + 12) + (6x + 30) + (2x + 8) = 180\\5x + 12 + 6x + 30 + 2x + 8 = 180

We add similar terms:

13x + 50 = 180\\13x = 180-50\\13x = 130\\x = \frac {130} {13}\\x = 10

Answer:

x = 10

Option D
