If the length of the side of a square is doubled, what is the ratio of the areas of the original square to the area of the new s
7nadin3 [17]

Answer:

\frac{1}{4}

Step-by-step explanation:

Let 's' be the side of the original square

the length of the side of a square is doubled, so the length of the new square is 2s

Area of the original square with side length 's' is s^2

Area of the new square with side length '2s' is (2s)^2=4s^2

Area of the new square is 4  times the area of the original square

ratio of the areas of the original square to the area of the new square

\frac{s^2}{4s^2} =\frac{1}{4}

1/5x-2/3y=30 when y=15
dolphi86 [110]

Answer:

Step-by-step explanation:

<u>Step 1:  Set y to 15 and solve</u>

<u />\frac{1}{5}x - \frac{2}{3}*15=30

\frac{1}{5}x-10=30

<em>Add 10 to both sides</em>

<em />\frac{1}{5}x-10+10=30+10

\frac{1}{5}x=40

<em>Multiply both sides by 5</em>

<em />\frac{1}{5}x*\frac{5}{1}=40*\frac{5}{1}

x=200

Answer:  x=200
