Answer:
2=x
Step-by-step explanation:
-2x+5=4x-7
+2x +2x
5=6x-7
+7 +7
12=6x
/6
2=x
Plug in numbers in for x.
If you plug in 0 then you get 1. 1/0 is undefined
If you plug in 1 then you get 6. 6/1 is 6
If you plug in 2 then you get 11. 11/2 is 5.5
If you plug in 3 then you get 16. 16/3 is 5.3 repeating
If you plug in 4 then you get 21. 21/4 is 5.25
If you plug in 5 then you get 26. 26/5 is 5.2
It would only be proportional if you got the same answer after dividing each time.
Answer: B. 41 3/5 ounces of icing per cake
Step-by-step explanation:
- 52/5 divided by 1/4. Keep 52/5, change the division sign into a multiplication sign, and flip 1/4 to 4.
- The new equation should be 52/5 * 4. The answer to this is 208/5, which simplified is 41 3/5.
7y - 3x = -5
-3x = -7y - 5
x = 7/3y + 5/3
