Answer:
65 miles
Step-by-step explanation:
Given:
- k = how many more miles Daniel has to walk
- Goal = 100 miles
- Daily miles = 5 miles
- Number of days already walked = 7 days
Equation:
5 × 7 + k = 100
Solving:
⇒ 5 × 7 + k = 100
⇒ 35 + k = 100
⇒ k = 100 - 35
⇒ k = 65
Answer:
D.) 1 + 1 + 5/8 + 2/8
Step-by-step explanation:
1 5/8 + 1 1/4
*set aside ones for a sec*
1/4 x 2/2 = 2/8
5/8 + 2/8
*get the ones back in*
1 + 1 + 5/8 + 2/8
First you would subtract Minas friends mile time from Minas mile time.
11.02-9.4
Mina is 1.62 minutes faster than her friend
Answer:
f(-2) = 4
Step-by-step explanation:
The function has three definitions depending on the value of x.
You are looking for the value of the function at x = -2.
-2 is in the interval x <= -1, which is the first line of the definition of the function.
We use the first line of the definition of the function.
f(x) = -2x for x <= -1
f(-2) = -2(-2) = 4
Answer: f(-2) = 4
