Answer:
The answer is 40
Step-by-step explanation:
28/x=7/10
firs you need to setup this equation and solve it to get 40
there are 12 girls in the band and 28 boys in the band and I know this because 12+28=40 just like 3/10 + 7/10= 10/10
12 divided by 4 is 3
28 divided by 4 is 7
Answer:
x = -19
Step-by-step explanation:
-10x - 19 = 19 - 8x
-10x + 8x = 19 + 19
-2x = 38
x = -19
The correct answer is "<span>Step 2; 6x − 8 = 12 + 2x."
</span>
The step that the student first make an error is at the 2nd step. The correct step should be 6x − 8 = 12 + 2x.
Finishing the steps:
<span>Step 1: 2(3x − 4) = 8 + 2x + 4
</span>Step 2: <span>6x − 8 = 12 + 2x.
Step 3: 4x = 20
Step 4: x = 5</span>
