3,128 = 42(p + 15)

We're trying to find p, which is quite simple.

Simplify.

3,128 = (42 · p) + (42 · 15)

Simplify.

3,128 = 42p + 630

Now, we subtract 630 from both sides.

3,128 - 630 = 42p

Simplify.

2,498 = 42p

Remember...we're simply just trying to isolate p. In order to do that, we must divide both sides by 42.

2,498 ÷ 42 = 42p ÷ 42

Simplify.

≈ 59 = p

** ≈ means "precisely" or "about" **

Therefore, p = 59

However, if your teacher does not want the rounded answer, then here is the full value of p : 59.4761904762
Hope I helped! :)

So, since she weights 6 times more on earth, say for every lb on the moon is 6lbs on earth then.

now, if 1lb on the moon is 6lbs on earth, how much is 90 earth lbs on the moon?

$\bf \begin{array}{ccll}
moon&earth\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&6\\
m&90
\end{array}\implies \cfrac{1}{m}=\cfrac{6}{90}\implies \cfrac{1\cdot 90}{6}=m$

Solve:7 +42-32-32 = 14.3-2a +7 A = -3 A= 0 A= 3 no solution

Answer:

a = 18.15

Step-by-step explanation:

$7+42-32-32=14.3-2a+7$

Combine like terms on the left side of the equation first. Add 7 and 42, then subtract 32 from the answer you get, then subtract 32 from that answer. This is going by order of PEMDAS.

Remember PEMDAS: (numbers 3 & 4 and numbers 5 & 6 are solved from left to right)
