Answer: 7. p=1.49

8. a= 1.05

Step-by-step explanation:

Answer:

p = 1.5   &   s = 7

Step-by-step explanation:

7. [tex]\frac{0.45}{4.2}[/tex] = [tex]\frac{p}{14}[/tex]

0.45(14) = 4.2p      ⇒ Cross-multiply the terms

6.3 = 4.2p                

p = [tex]\frac{6.3}{4.2}[/tex]                     ⇒ Divide 6.3 by 4.2 to get p by itself (solve for p)

p = 1.5

8. [tex]\frac{2.4}{6}[/tex] = [tex]\frac{2.8}{s}[/tex]              

2.4s = 6(2.8)          ⇒ Cross-multiply the terms

2.4s = 16.8

s = [tex]\frac{16.8}{2.4}[/tex]                   ⇒ Divide 16.8 by 2.4 to get s by itself (solve for s)

s = 7

I would really appreciate it if you would please mark me brainliest!

Have a blessed day!
