Answer:
Step-by-step explanation:
4^2 = 4 * 4 = 16
2^2 = 2 * 2 = 4
4^2 +4^2 +2^2 = 16 + 16 + 4 = 36
3.606 is the answer
H^2 = P^2 + B^2
H^2 = 3^2 + 2^2
H^2 = 9+4
H^2 = 13
H = root 13
H = 3.606 (simple radical Form)

Answer:
Step-by-step explanation:
If the amounts earned from the sale of each item were the same, then both amounts were $2400/2 = $1200.
The number of balloons sold at $3 each was $1200/$3 = 400.
The number of banners sold at $4 each was $1200/$4 = 300.
400 balloons and 300 banners were sold.
___
<em>Check</em>
Total sales was ...
$3 × 400 + $4 ×300 = $1200 +1200 = $2400 . . . answer checks OK
Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.
3x + 7 = x - 9
2x + 7 = -9
2x = -16
x = -8
Hope this helps :)
