Answer:

ngle A=77

Angle B=103

Step-by-step explanation:

∠A+∠B=180 ( supplementary  angles)

3/8 x  +50+x+31=180

3/8 x+x=180-81

11/8 x=99

11x=99*8

x=(99*8)/11 =72

Angle A= 3/8 (72)+50

Angle A=27+50=77

Angle B= 72+31=103

Answer:

m<a = 77

m<b= 103

Step-by-step explanation:

m<a+m<b = 180(supplementary angles)

3x/8+50+x+31=180

3x/8+x+81=180

(3x+8x)/8=180-81

3x+8x=99*8

11x=792

x=792/11

x=72

now

m<a=3x/8+50

=(3*72)/8+50

=77

m<b=x+31

=72+31

=103

Answer:

<em>The width of the lid is 15 cm</em>

Step-by-step explanation:

<u>The Perimeter of a Rectangle</u>

Given a rectangle of width W and height H, the perimeter is calculated as:

P = 2(W + L)

Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:

2(W + L) = 56

Dividing by 2:

W + L = 28

Since the lid was L=13 cm long, the width is:

W = 28 - 13 = 15

The width of the lid is 15 cm

Y= 1/2x+ 2 to make the x the subject.
timofeeve [1]

Answer:

x=2y-4

Step-by-step explanation:

y=\frac{1}{2} x+2

"To make x the subject" means to have the equation with all the terms in x on one side. As of now, y is the subject of the equation.

You start by subtracting 2 from both sides, you should get the following.

y-2=\frac{1}{2} x

Then you multiply by 2 from both sides, you should end up with the following.

2(y-2)=x

Therefore, you get the following.

x=2(y-2)

Finally, you distribute and get the answer.

x=2y-4
