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
Area of rectangle : A = LW
19. A = 3p^4 * p^2 = 3p^6 (when multiplying exponents with the same base, u add the exponents)
20. A = 7z^5 * 6z^3 = 42z^8 (because 7 x 6 = 42, and z^5 * z^3 = z^8)
Slope intercept is y = mx + b
b is 1470
2x + 3y = 1470
2x (-2x) +3y = 1470 - 2x
3y = -2x + 1470
3y/3 = (-2x + 1470)/3
y = -2/3x + 490
hope this helps
