Answer:
16
Step-by-step explanation:
128 stamps and 8 pages have the same amount to add up to 128
So 128 ÷ 8 I'll make it easier
8÷8=1
40÷8=5
80÷8=10
(128÷8)
10+5+1 = 16
There are 16 stamps per page.
120 / 18 = 20/3
x^3 / xy = x^2 / y
20x^2 / 3y
Answer:
520 miles
Step-by-step explanation:
65 mph * 8 hours = 520 miles
I hope this helps :)
To solve this you must replace x with -4 and y with 5 in the equation 7x + y² like so:
7 × (-4) + 5²
To solve this use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
Exponent...
7 × (-4) + 5²
5² = 5 × 5 = 25
7 × (-4) + 25
Multiplication...
7 × (-4) + 25
7 × (-4) = -28
-28 + 25
Addition...
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 28 and its sign is negative. Your answer will have a negative sign.
-28 + 25 = -3
-3
