The answer is -4 2/3
Explanation : The elevator is at 0, and went below ground level 90 feet, that would be -90, then it went up 20 feet, which would be -90 + 20 = -70
-70 ft / 15sec = - 4 2/3
I am not sure about the ground level and negative difference but that it is what I was taught. Below ground level is negative and above is positive. Therefore the elevator traveled up and it traveled -4 2/3 per second.
It so either 4 2/3 or - 4 2/3 but pretty sure it is - 4 2/3.

This is the concept of algebra, To solve the question we proceed as follows;
Number of chocolate cake left=23
The number of pieces that was left after the cake was divided into 2 equal pieces will be:
23*2
=46
Number of strawberry cake left = 56
The number of pieces that was left after the cake was divided into 3 equal pieces will be:
56*3
=168
Comparing the two fraction, the flavor that had larger pieces was strawberry cake;
This cake was larger compared to chocolate by:
168-46
=122
The answer is Strawberry by 122 of a cake
Answer:
41.2
miles
Explanation:
To solve the question, first find the number of miles Rachel power walked.
She walked
2
3
5
or
2.6
miles a day for seven days. Multiply seven days by
2.6
to find the total number of miles Rachel power walked that week.
2.6
⋅
7
=
18.2
Next, find the number of miles Rachel jogged.
She jogged
5.75
miles a day for four days. Multiply
4
by
5.75
to find the number of miles Rachel jogged that week.
5.75
⋅
4
=
23
Rachel power walked 18.2 miles and jogged 23 miles. Add the two values up to find the total number of miles that she power walked and jogged.
18.2
+
23
=
41.2
