Joanna is driving 185 miles to visit her family. She drives 68 miles in the morning, stops for lunch, and then drives the rest o
f the distance. How many miles did she drive after lunch?
Use the variable m to represent the number of miles she drove after lunch.
Which equation represents this situation and its solution?
1 answer:
Answer:
68+m=185
m=117
Step-by-step explanation:
68 miles before lunch, plus m miles after lunch is a total of 185 miles. Assuming she reaches her destination. That creates the equation 68+m=185
Then, to figure out the miles she travels after lunch we solve for m:
do this by subtracting 68 from both sides. This leaves us with: m=117

Answer:
subtraction
Step-by-step explanation:
to start off the process of finding the answer to the equation you would have to subtract 5 from 9
Answer:
f(4) is 9
f(-5) is -9
f(0) is 1
f(1/2) is 2
Absolute value, aka same distance from 0
for example |5| is five numbers away from zero and |-5| is also five numbers away from zero
Answer:
-10
Step-by-step explanation:
7 + 7(-4) - (2(-4)) + 3
7 - 28 - (-8)+3
7 - 28 +8 +3
= -10
