Answer:
y = 60
Step-by-step explanation:
<h3>Step 1: Make sense of the given</h3>"The ratio of y to x is 3"
This means that,
"The sum of y and x is 80"
This means,
If , then
.
We can plug this into the other equation by substitution:
This simplifies to:
Which we can solve out and get:.
We solved for x, but we need the value of y.
So, we go back to the equation we first derived: "".
And now we substitute the value of x, into this.
By solving this out, we get:
So, the value of y is 60.
Answer:
Step-by-step explanation:
If you have a square of side , its diagonal would be
, and its area
If the big square has a area of 900, this implies that its side is , so the two diagonal of squares 2 and 4 added together would be
, therefore one diagonal wold be
. and its side
. The area (of one square) is
finally the two areas combined (squares 2 and 4) would be 225
