I think it’s z=1 hope this helps
Answer:
z=-1
Step-by-step explanation:
-2(4z-4)=10-6z
First, distribute the -2 into the parenthesis to get:
-8z+8=10-6z
Then, add 8z to each side to eliminate it from the left side to get:
8=10+8z-6z
Simplify the right side and combine the z's:
8=10+2z
Subtract 10 from BOTH sides to get:
-2=2z
Finally, to get z alone, divide everything by 2 to get:
-1=z or z=-1

What is the volume of this rectangular prism?
Answers
Answer: V≈5.21 cm³
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply the length, width and height.
[tex]V=wlh[/tex]
Since we were given the length, width and height, we can directly multiply them together.
[tex]V=\frac{5}{2} *\frac{5}{3} *\frac{5}{4}[/tex] [multiply]
[tex]V=\frac{125}{24} =5.21 cm^3[/tex]
Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.

x = 10
PT = 34
Step-by-step explanation:
PT = 4x - 6 and TQ = 3x + 4
if PT = TQ
4x - 6 = 3x + 4
4x - 3x = 4 + 6
x = 10
PT = 4x - 6
PT = 4 (10) - 6
=40 - 6
PT = 34
The value of PT = 34
It takes 2 finish carpenters 8 days to do the work. Each finsh carpenter ears $37.50 per hour and works 7 hours per day. How much will it cost to hire the finish carpenters?
Answers
Answer:
Total cost= $4,200
Step-by-step explanation:
Giving the following information:
It takes 2 finish carpenters 8 days to do the work.
Each finish carpenter ears $37.50 per hour and works 7 hours per day.
To determine the total cost, first, we need to structure the total cost formula:
Total cost= 2*(37.5x)
x= total number of hours
Now, for 8 days:
Total hours= 8*7= 56
Total cost= 2*(37.5*56)
Total cost= $4,200

Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered the greatest area. Who is correct? Justify your answer using mathematical reasoning.
Answers
Answer:
Perry is correct, she covered the greatest area = 18 square units.
Step-by-step explanation:
Looking at the attached diagram, the shapes are rectangular and they are on grid or graph
Note that on a graph:
1 square box = 1 unit
Area of rectangle = Length × Width
For Karina
The Width = 3 units
The length = 4 units
The area which Karina covered = 3 units × 5 units
= 15 square units
For Perry
The Width = 9 units
The length = 2 units
The area perry covered = 9 units × 2 units
= 18 square units
Therefore, Perry is correct, she covered the greatest area = 18 square units.

The next customer ordered 4 banana splits and 3 hot fudge sundaes and paid $29. How much does each item cost?
Answers
Answer:
$5 and $3
Step-by-step explanation:
Cost of banana split = b
Cost of hot fudge sundae = s
b + 2s = 114b + 3s = 29From the first equation we get:
b = 11 - 2sReplacing in the second equation:
4(11 - 2s) + 3s = 2944 - 8s + 3s = 2944 - 29 = 5s15 = 5ss = 15/5s = 3Then
b = 11 - 2*3 = 11 - 6 = 5So banana split costs $5 and hot fudge sundae costs $3

Answers
Answer:
3ny
Step-by-step explanation:
For this problem, the price of a widget is represented by 'n' amount of dollars. Additionally, the store was stocked with 4y widgets.
To find the total cost of the widgets sold, we will use the information that at the end of the day, the store only had y widgets remaining.
From here we can say the following to represent the total cost of the widgets sold:
cost = n * (4y - y)
cost = n * (3y)
cost = n3y
You can rewrite this cost to be 3ny as in the answer choice.
