Answer:

Length = 18\frac{2}{5} feet

Step-by-step explanation:

Simplify the fraction of the width:

12\frac{1}{2}=\frac{25}{2}

Using the formula for Area:

A=l*w\\l=\frac{A}{w}

Substituting the known values:

l=\frac{230}{\frac{25}{2}}\\l=230*\frac{2}{25}\\l=\frac{460}{25}\\l=\frac{92}{5}\\l=18\frac{2}{5}

The sum of three numbers is 88. The first number is 8 more than the second. The third number is 3 times the second. What are the
Sever21 [200]

Answer:

The numbers are 24, 16 and 48

Step-by-step explanation:

For this equation you need to use all the information you have to add in 3 variables, use the information you have to connect them, so you only use one number. You’ll have the second number (x), the first number (x+8) and the third number (3x) now we use all of that to make an equation.

88=x+(x+8)+3x

Now you simplify the equation,

88=5x+8

Now get the x and it’s coefficient alone on one side

80=5x

Now divide both sides so the x is alone

x=16

Since the second number was x you know the second number

the first number is x+8 since x is 16 the first number is 24

The third number is 3 * x so the third number is 48.

So the numbers are 24, 16 and 48
