The equation y=3.2x represents the cost y (in dollars) for a taxi ride during peak hours that costs x dollars during off-peak hours. a. Solve the equation for x.
Answer:
x = y / 3.2
Step-by-step explanation:
Given:
y = 3.2x
Where
y = cost for a taxi ride during peak hours (in dollars)
x = cost for a taxi ride during off-peak hours (in dollars)
Solve the equation for x.
y = 3.2x
Divide both sides by 3.2
y / 3.2 = 3.2x / 3.2
y / 3.2 = x
x = y / 3.2
This means,
Cost for a taxi ride during off-peak hours (in dollars) = Cost for a taxi ride during peak hours (in dollars) / 3.2

7 students have 3 books each. Which helps you find the total number of books?
Answer:
21 Books in total
Step-by-step explanation:
If you just want the total number of books, here:
If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books
7 * 3 = 21 so There are 21 books in total
Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.
Answer:
21 books in total
Step-by-step explanation:
If there is 7 students who have 3 books each, and want to find the total. The easiest way is multiply 7 with 3 to give you an answer of 21
Or draw a picture if it helps
Draw 7 stick figure and under it draw 3 books for them and count the books, still gives you 21
I think this is what you want
Ms. Albero decided to make juice to serve along with the pizza at the Student Government party. The directions said to mix 2 scoops of powdered drink mix with a half gallon of water to make each pitcher of juice. One of Ms. Albero’s students said she will mix 8 scoops with 2 gallons of water to make 4 pitchers. How can you use the concept of proportional relationships to decide whether the student is correct?
Step-by-step explanation:
2scoop: .5 gal= ONE PITCHER
1scoop: .25gal= HALF PITCHER
×8
8scoop: SHOULD BE 2gal= 4 PITCHERS
Answer: The student is correct.
Step-by-step explanation:
Consider the provided information.
The directions said to mix 2 scoops of powdered drink mix with a half gallon of water to make each pitcher of juice.
This can be written as:
2 scoops = 1/2 gallons of water
Multiply both side by 2
2×2 scoops = 2×1/2 gallons of water
4 scoops = 1 gallons of water
That means Ms. Albero wants 4 scoops for each gallons of water.
Albero’s students said she will mix 8 scoops with 2 gallons of water to make 4 pitchers.
This can be written as:
8 scoops = 2 gallons of water
Divide both side by 2.
8/2 scoops = 2/2 gallons of water
4 scoops = 1 gallons of water
That means Albero’s students used 4 scoops for each gallons of water, which is the same quantity of scoops per gallons as suggested by the Ms. Albero.
So the student is correct.

Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero. Which statement must be true? The pool must have been empty for the entire interval. The pool must have been the same depth at the start of the interval as it was at the end of the interval. The pool must have been deeper at the end of the interval than it was at the start of the interval. The pool must have been more shallow at the end of the interval than it was at the start of the interv
Answer:The pool must have been the same depth at the start of the interval as it was at the end of the interval.
Step-by-step explanation:
The average rate of change is calculated as:
[final value - initial value] / time interval.
Then, the average rate of change does not take into account intermediates values, and you cannot draw any conclusion about such intermediate values.
In the given case you have:
average rate of change in depth = [final depth - initial depth] / 2 weeks.
0 = [final depth - initial depth] / 2 weeks.
⇒ 0 = final depth - initial depth
⇒ final depth = initial depth.
That is why the conclusion is the second statement of the answer choices: the pool must have been the same depth at the start of the interval as it was at the end of the interval.
In between the pool might have been deeper, more shallow, empty or change in any form, since the average rate of change does not tell the full history but only the net change.
Answer:
The pool must have been the same depth at the start of the interval as it was at the end of the interval.

3x - 6x + 2 > 65
Mathematic
3x - 6x + 2 > 65
Combine like terms.
-3x + 2 > 65
Subtract 2 from both sides.
-3x > 62
Divide both sides by -3
x < -62/3
Answer:
3x - 6x + 2 > 62
→ -3x + 2 > 62
→ -3x > 62
→ x < -62/3
