1) Find x
The equation is:
4x=64

x=64/4=16

answer: x=16º

2)Find y:
The equation is:
(2y)+(3y+5)=180
5y=180-5
5y=175
y=175/5
y=35

Answer: y =35º

Find the measure of each angle...
3)∠a
2y+4x+a=180
2(35º)+4(16º)+a=180º
70º+64º+a=180º
a=180º-70º-64º=46º

Answer: ∠a=46º.

4)∠b
a+b=180º
46º+b=180º
b=180º-46º
b=134º

Answer: ∠b=134º

5)∠c
a+c=180º
46º+c=180º
c=180º-46º
c=134º

Answer: ∠c=134º

6)∠d
112º+d=180º
d=180º-112º
d=68º

Answer: ∠d=68º

7) ∠e
64º+d+e=180º
64º+68º+e=180º
e=180º-64º-68º
e=48º

Answer: ∠e=48º

8)∠f
e+f=180º
48º+f=180º
f=180º-48º
f=132º

Answer: ∠f=132º

MANUFACTURING A shoe manufacturer spends $2.50 to make sandals and $4 to make running shoes. During a typical month, they spend
jonny [76]

Answer:

200 pairs of sandals

Step-by-step explanation:

Represent the sandals with x and the running shoes with y.

In a typical month:

Total = 2500

In April

Total = 3000

Required

The number of sandals in a typical month

<u>In a typical month:</u>

If 1 sandal costs 2.50, then x costs 2.50x

If 1 running shoe costs 4, then y costs 4y

The total is:

2.50x + 4y = 2500

<u>In April:</u>

If 1 sandal costs 2.50, then 2x costs 5x ---- <em>we used 2x because the pairs is doubled </em>

If 1 running shoe costs 4, then y costs 4y

The total is:

5x + 4y = 3000

The equations are:

5x + 4y = 3000

2.50x + 4y = 2500

Subtract

5x - 2.50x + 4y - 4y = 3000 - 2500

2.50x = 500

x = \frac{500}{2.50}

x = 200

Kazeer [188]

Answer:

  8/45

Step-by-step explanation:

Define x to be the value of your fraction:

  x=0.1\overline{7}\\\\10x=1.7\overline{7}\qquad\text{multiply by 10}\\\\10x-x=1.7\overline{7}-0.1\overline{7}=1.6\\\\x=\dfrac{1.6}{9}=\dfrac{8}{45}\qquad\text{divide by 9; put in lowest terms}

____

When in doubt, you can use your calculator to see which fraction gives you 0.1777777778.

_____

We multiplied by 10^1 above, because there is 1 repeating digit. The power of 10 we use matches the number of repeating digits.
