Answer:

1. x= -1

2. y= 4

Step-by-step explanation:

1. -4x + 7 = 11 2. 17 = 5y -3

-4x + 7-7= 11 -7 17 + 3 = 5y -3 +3

-4x = 4 20 = 5y

x= 4/-4 20/5 = y

x = -1 4 = y

Step-by-step explanation:

Given

Gavin and his three friends wants to share $\frac{1}{3}$ of cake equally.

Angle A and angle B are complementary angles. If m∡a = 4x and m∡b = 3x +13, what is the measure of the smaller angle?

bagirrra123 [75]

Answer:

Step-by-step explanation:

Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.

4x+3x+13=90

-13 -13

7x=77

/7 /7

X=11

Now plug in the value of x.

A=4(11) B=3(11)+13

A=44. B=33+13

B=46

Angle a is the smaller angle and measures at 44°
