Answer:
B. 6,-6
Step-by-step explanation:
X^2 + 12 = 48
Subtract 12 from each side
X^2 + 12-12 = 48-12
X^2 = 36
Take the square root of each side
sqrt(X^2 ) = sqrt(36)
X = ±6
Answer:
Lin will run 1 mile in 8/55 of an hour
Noah will run 1 mile in 2/13 of an hour
Step-by-step explanation:
Here;
Lin ran 2 3/4 miles in 2/5 of an hour
he will run 1 mile in x hour
x * 2 3/4 = 2/5 * 1
2 3/4 = 11/4
x * 11/4 = 2/5
x = 2/5 * 4/11
x = 8/55 hour
For Noah
8 2/3 miles in 4/3 of an hour
1 miles in y hours
y * 8 2/3 = 4/3 * 1
y * 26/3 = 4/3
y = 4/3 * 3/26
y = 4/26 = 2/13
He will run 1 mile in 2/13 hours
