Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
5x - 7 = 18
Step 2: Solve for <em>x</em>
- Add 7 to both sides: 5x = 25
- Divide both sides by 5: x = 5
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(5) - 7 = 18
25 - 7 = 18
18 = 18
4(y= 1/2x -4)
4y = 2x -16
y= -2x -9
5y = -25
Y= -5
So since there is only one answer with y= -5 the answer is A
Hope this helps!

C.

First you must divide, 650/10. Which will equal to 65. Subtract 65 from 650. You will end up with 585. To represent the amount that is left would be 9/10,
600 grams = 0.6 kilograms
0.6 x 4 = 2.4 kilograms
