Answer:

10+12.50h=5+15h

We move all terms to the left:

10+12.50h-(5+15h)=0

We add all the numbers together, and all the variables

12.50h-(15h+5)+10=0

We get rid of parentheses

12.50h-15h-5+10=0

We add all the numbers together, and all the variables

-2.5h+5=0

We move all terms containing h to the left, all other terms to the right

-2.5h=-5

h=-5/-2.5

h=+2

Step-by-step explanation:

Mario is constructing a square dart board. It will consist of a smaller square centered in a larger square. The smaller square m
Ivan

Answer:

6 inches.

Step-by-step explanation:

Let a represent side length of larger square.

We know that area of square is square of its side length, so area of the larger square will be a^2.

The area of smaller square would be 4^2.

We will use proportions to solve our given problem.

\frac{\text{Area of smaller square}}{\text{Area of larger square}}=\frac{4}{9}

\frac{4^2}{a^2}=\frac{4}{9}

\frac{16}{a^2}=\frac{4}{9}

Cross multiply:

4*a^2=16*9

\frac{4*a^2}{4}=\frac{16*9}{4}

a^2=36

Take square root:

a=\pm\sqrt{36}

a=\pm 6

Since the length cannot be negative, therefore, the side length of larger square is 6 inches.

I am Lyosha [343]

Answer:

Follows are the solution to the given points:

Step-by-step explanation:

Given:

A) \ \ 2x+(3.4)^2+(7.7) \\\\B) \ \ 3x+(2.6)+(8.8)^2\\\\C)\ \ 7.6+(28.3)+(4)^2 \\\\D)\ \ 7x-(7.8)+(9:3)

For point A:

\to  2x+(3.4)^2+(7.7)\\\\\to  2x+(11.56)+(7.7)\\\\\to  2x+19.26\\\\

For point B:

\to 3x+(2.6)+(8.8)^2\\\\\to 3x+(2.6)+77.44\\\\\to 3x+80.04

For point C:

\to \ 7.6+(28.3)+(4)^2 \\\\\to \ 7.6+(28.3)+16 \\\\\to \ 7.6+44.3 \\\\\to 51.9

For point D:

\to 7x-(7.8)+(9:3)\\\\\to 7x-(7.8)+ \frac{9}{3}\\\\\to 7x- \frac{23.4+9}{3}\\\\\to 7x- \frac{32.4}{3}\\\\\to 7x- 10.8
