5x + 2y = 15
y = -3x - 2......so sub in -3x - 2 in for y in the other equation

5x + 2(-3x - 2) = 15
5x - 6x - 4 = 15
5x - 6x = 15 + 4
-x = 19
x = -19

y = -3x - 2
y = -3(-19) - 2
y = 57 - 2
y = 55

so ur solution is (-19,55)

A book sold 33,200 copies in its first month. Suppose this represents 7.4% of the number of copies sold to date. How many copies
Marta_Voda [28]

Answer: 448648

Step-by-step explanation:

33,200 copies represent 7.4% of the total amount

-----------------------------------------------------

#1  33,200 ÷ 7.4%

- this is because how we get 33,200 by calculation is use the total amount and times 7.4% to get 33,200. So we are just working backwards. Since it was times before, then we divide after.

 33,200÷7.4%

=33,200÷0.074

≈448648 (you can't round up when the real amount is less the exact amount)
