can you please help me with number 10 part A

Answer:
p = 54
Step-by-step explanation:
Isolate [tex]\frac{1}{3}[/tex] p by subtracting 7 from both sides
[tex]\frac{1}{3}[/tex] p = 18
Multiply both sides by 3
p = 18 × 3 = 54
Answer:
[tex]\large\boxed{p=54}[/tex]
Step-by-step explanation:
[tex]\dfrac{1}{3}p+7=25\qquad\text{subtract 7 from both sides}\\\\\dfrac{1}{3}p+7-7=25-7\\\\\dfrac{1}{3}p=18\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{1}{3\!\!\!\!\diagup_1}}p=3\cdot18\\\\p=54[/tex]
