1.89 + 3.72 = 5.61
10.75 - 5.61= 5.14
5.14 x 100= 514
0.64 x 100= 64
(You can skip out the multiplying by 100 but doing this step makes it easier to do without a calculator)
514/64= 8.3
Round the number down to 8 and this is your answer.

Answer:
x = 3 and y = 2
Step-by-step explanation:
y = 3x - 7
substituting for y in 4x + 3y = 18, we will have
4x + 3(3x -7) = 18
4x + 9x - 21 = 18
13x = 18 + 21
13x = 39
x = 3
Substituting for x in y = 3x -7, we have
y = 3(3) - 7
y = 9 - 7
y = 2
