Answer:
21,000
Step-by-step explanation:
front end estimation requires you to take the front / first digit of each number in this expression and round.
if you don't know how to round, basically you take the next digit after the first one, (in 719 you take the 1) and determine if that's below or above 5. If below, then keep the original first number. If above, add one more to the first digit. If the number is five itself, it is most common to round up (so add one).
like 425 would round to just 400; and 676 would round to 700.
multiply 700 and 30
youd get 21000
Every foot is composed of 12 inches. Below is the way to solve the number of inches (n) in 12 ft.
n = (12 ft) x (12 inches / 1 ft) = 144 inches
To determine the number of 2-inch segments, divide 144 inches by 2. The division gives an answer of 72. Thus, there are 72 2-inch segment in 12 ft.
Answer:
x = 2
y = -5
Step-by-step explanation:
2x - y = 9
y = x - 7
2x - y = 9
2x - (x - 7) = 9
2x - x + 7 = 9
x + 7 = 9
x = 2
y = x - 7
y = 2 - 7
y = -5
