I'm not sure what you're asking.... but
18+18=36
36 divided by 9 is equal to 4
the answer is 4
<u>Answer</u>:
x = 5
<u>Explanation</u>:
If the angle are parallel:
step 1:
21x + 7 = 22x + 2
21x - 22x = 2 -7
-x = -5
x = 5
finding upper angle, then when both lies on straight line equals to 180°
step 2:
180 = (180 - 22x - 2 ) + 21x + 7
180 = 180 - 2 + 7 - 22x + 21x
180 = -x 185
-5 = -x
x = 5
Answer:
5 degrees
Step-by-step explanation:
If it is a fraction like (3a-3b)/(3a+12b)
= [3(a-b)]/[3(a+4b)]
= (a-b)/(a+4b)
Answer:
![30\ miles\ per\ gallon](https://tex.z-dn.net/?f=30%5C%20miles%5C%20per%5C%20gallon)
Step-by-step explanation:
we know that
To find out the unit rate divide the total miles by the total gallons
Let
x ----> the number of miles
y ----> the number of gallons
![unit\ rate=\frac{x}{y}](https://tex.z-dn.net/?f=unit%5C%20rate%3D%5Cfrac%7Bx%7D%7By%7D)
we have
![x=30\ miles\\y=1\ gallon](https://tex.z-dn.net/?f=x%3D30%5C%20miles%5C%5Cy%3D1%5C%20gallon)
substitute
![\frac{30}{1}=30\ miles\ per\ gallon](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B1%7D%3D30%5C%20miles%5C%20per%5C%20gallon)
