Question

1. $\frac{v}{7}=8$ 28) $a + 11 = 20$ 29) $-7 + m = 8$ 30) $18 + m = 8$

Explanation:

Step1: Solve for \(v\) in \(\frac{v}{7}=8\)

Multiply both sides by 7. So \(v = 8\times7=56\).

Step2: Solve for \(a\) in \(a + 11=20\)

Subtract 11 from both sides. Then \(a=20 - 11 = 9\).

Step3: Solve for \(m\) in \(-7 + m=8\)

Add 7 to both sides. We get \(m=8 + 7=15\).

Step4: Solve for \(m\) in \(18 + m=8\)

Subtract 18 from both sides. Thus \(m=8-18=- 10\).

Answer:

1. \(v = 56\)
2. \(a = 9\)
3. \(m = 15\)
4. \(m=-10\)
