Answer:
x= -1.
Step-by-step explanation:
4-2(x+7) = 3(x+5)
4 - 2x-14 = 3x +15
10-2x=3x+15
10=5x+15
-5 = 5x
-1 = x

Okay for this question, you make a simple equation: (1/3)x=(1/4)y to represent the ratio between the milk and water. Then to find how many cups of water are needed for each cup of milk, you plug in 3 for x (because 1/3 times 3 equals one cup) and solve for your y value. Your final equation for solving should look like: (1/3)(3)=(1/4)y
Answer:
x=6
Step-by-step explanation:
you dived the 5 to get x by itself and 5 dived by 30 is 6
Answer:
(90,60)
Step-by-step explanation:
if you look closely through the linear graph, the line crosses through (90,60) and not the other given pairs.
- proportional relationships are plots that also match in the same graphing format (keep in mind when you have trouble next time)
For E to be the midpoint of DF, it needs to divide DF in 2 equal segments, DE and EF. If E is the midpoint of DF, then DE and EF are equal, so the reason is that the expressions for DE and EF are equal. The reason is:
