140 - 50 = 90
90 / 25 = 3.6
3.6 x 36 = 129.9
Final Answer:
$129.9 for 36 extra miles.
Answer:
I simply separated the number into two numbers that I know are directly related to 9. 90 and 45 gives me around 135 ignoring the 22 cents since this is an estimation. 9*10 is equal to 90 and 9 times 5 is equal to 45. So I can estimate that the answer is around 15.

Answer:
55 cm²
Step-by-step explanation:
side length of square = perimeter/4 = 40/4 = 10 cm.
area of square = side x side = 10 x 10 = 100 cm²
area of triangle #1 = 1/2bh = 1/2(3)(10) = 15
area of triangle #2 = 1/2bh = 1/2(6)(10) = 30
100 - 15 - 30 = 55 cm²
Answer:
<h3>B. -84</h3>
Step-by-step explanation:
Taking the determinant of the matrices we will have;
= 4x(5y) - 2x(3y)
= 20xy - 6xy
= 14xy
Given x = -2 and y = 3
Determinant = 14(-2)(3)
Determinant = -28*3
Determinant = -84
Answer:
5
Step-by-step explanation:
5 because of two ways one you could do 6*what is 30. Or you could do repeated addition 30=5+5+5+5+5+5. But when you do 30=5-5-5-5-5-5. You are doing repeated subtraction which is equivalent to 30-5*6= 0.
