A=1/2(w)h. What is the equation solved<br> for h?
MissTica

Answer: h=\frac{2A}{w}

Step-by-step explanation:

To solve for h, we want to use our algebraic properties.

A=\frac{1}{2}wh                             [multiply both sides by 2]

2A=wh                             [divide both sides by w]

h=\frac{2A}{w}

Now, we have h alone. h=\frac{2A}{w} is our answer.

Jess is 12 years less than half as old as Mac. The sum of their age is 87. How old is each person?
laila [671]

Answer:

The age of each person is:

  • Jess is <u>21</u> years old.
  • Mac is <u>66</u> years old.

Step-by-step explanation:

To solve this problem you must make two equations. First, we name Jess and Mac as variables:

j = Jess age.

m = Mac age.

Now we make the equations, the first equation has the information "Jess is 12 years less than half as old as Mac":

1. j=(\frac{m}{2})-12

The second equation has the information "The sum of their age is 87":

2. j+m=87

Now, we replace the first equation in the second one:

  • (\frac{m}{2}-12) +m=87

And we operate:

  • \frac{m-24}{2} +m=87
  • \frac{m-24+2m}{2}=87
  • \frac{3m-24}{2}=87

We clear the variable m:

  • 3m-24=87*2
  • 3m=174+24
  • m=\frac{198}{2}
  • m=66

How we know Mac's age is 66 years old, we can identify Jess' age with the second equation:

  • j+m=87

We replace the value of m:

  • j+66=87

And clear the variable j:

  • j=87-66
  • j=21

In the end, Jess's age is 21 years old.
