Wherever you see 'b', replace it with 3, since b = 3
So,
b^(-2) = 1/(b^2)
b^(-2) = 1/(3^2)
b^(-2) = 1/9
Ethan needs to save at least $500 to purchase a new dirt bike. So far, he has saved $175. If he hopes to use two-fifths of his next paycheck to cover the remaining amount, how much money must he make in his paycheck?
Define a variable, set up an inequality, then solve.
Answer: Inequality: 175+2x/5 ≥ 500. He must make $812.5 or more in his paycheck
Step-by-step explanation:
175+2x/5 ≥ 500
2x/5 ≥ 500-175
2x/5 ≥ 325
2x ≥ 325*5
2x ≥ 1,625
x ≥ 1,625/2
x ≥ 812.5

For every 1/2 mile that Ria runs, she walks 3/4 miles. What unit rate gives the number of miles Ria runs for every mile she walks?
A) 2 miles run to 3 miles walk
B) 2/3 miles run to 1-mile walk
C) 3 miles walk to 2 miles run
D) 3/2 miles walk to 1-mile run
Answer: A do
Step-by-step explanation: Because for every two mile she run she walk three mile
Answer:
I think the answer is A because if she runs 2 miles then that means 1/2, 4 times and then there is the other part witch is the 3 miles and that means 3/4 miles, 12/4. 12/4=3 (4 x 3=12) so the answer is: A) 2 miles run to 3 miles walk
