OMG I HAD THIS EXACT HOMEWORK LAST YEAR CREEPYYYYY!!!!
A is proportional
B is not
C is proportional I think
First of all, you can move the +2x to the other side:
-11 = -26 - 2x
Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x
Then you can divide both sides by 2:
7.5 = -x
Then you can flip the sides and the signs around:
x = -7.5
No, The answer is not -7, it is -7.5
Hope this helps! :)
U=5
x=1
z=-1.7
m=2
Trololololololo
30% of 40 = 0.30(40) = 12......so 12 tables seat 4 people per table = 12 x 4 = 48 seats.......tables remaining seat 22 people (22 seats).
48 + 22 = 70 seats total
Answer:
180 feet
Step-by-step explanation:
The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.
But,
1 inch = 12 feet
So that,
48 inches = x feet
⇒ x = 
= 4
Thus,
48 inches = 4 feet
The number of feet of fabric needed for 45 curtains can be determined as:
45 x 4 feet = 180 feet
Therefore, 180 feet of fabric would be needed to make 45 curtains.
