Answer:
z = -6
Step-by-step explanation:
5z + 2 = 3z - 10
Subtract 3z from both sides
2z + 2 = -10
Subtract 2 from both sides
2z = -12
Divide each side by 2
z = -6
So, the answer is z = -6

a.the average size of a seventh-grade class is larger and varies more than that of a kindergarten class
Step-by-step explanation:
ok so we know the mean and the m.a.d of both data sets, so now all we have to do is analyze the data
so the class ranges for kindergarten is 17-21

here's where i prove 'a' to be the correct answer;
21-17=4
34-25=9
the ranges for 7th grade is 5 more than that of a kindergarten class making 'a' the right answer
**i know i'm not an expert but an ace, i've just been trying to become a genius, sorry :(**
good luck :)

Nathena needs to buy a fence to put around her rectangular yard for her dog. Nathena forgot the width of his yard, but knows the legth is 30 yards. Her husband told her to buy 180 yards of fence. What is the greatest possible width for Nathena's yard?
Answer:
The real answer is 6
Step-by-step explanation:
Fairly simple. You know the length and the area, but you don't know the width. So your equation looks like this: 30 x ? = 180. But to figure out the width, you change the position of the numbers in the equation like this:
180 ÷ 30 = ?. Then you solve. 180 ÷ 30 = 6. If you want to double check your answer, you can plug in your answer to your original equation, 30 x 6 = 180.

Hayden drives a taxi cab and receives $200 a day plue $0.25 for every mile he drives. He is saving up for a new laptop that costs about $1800. If Hayden drives an average of 300 miles per day, how many days will he have to drive to save enough money to buy the laptop?
Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.
Given:
Daily base pay = $200
Earnings per mile driven = $0.25
Cost of the laptop = $1800
Average miles driven per day = 300
The basic arithmetic operations have been used to solve this question
1. Calculating the total earnings per day.
Total earnings per day = Daily base pay + (Earnings per mile driven × Average miles driven per day)
Total earnings per day = $200 + ($0.25 × 300)
Total earnings per day = $200 + $75
Total earnings per day = $275
2. Determining the number of days required to save enough money for the laptop.
Number of days = Cost of the laptop ÷ Total earnings per day
Number of days = $1800 ÷ $275
Number of days ≈ 6.545 (rounded to the nearest whole number)
Therefore, Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.

How many cuts do you need to cut a stick into:
6 parts?
11 parts?
x parts?
Answer:
5,10,1.
Step-by-step explanation:
I'm not sure about the last one but I tried. hope this helped.
Answer:
5 cuts, 10 cuts, and for the last one it is an equation.
x parts - 1 = amount of cuts for x parts.
Step-by-step explanation:
I cannot upload an image but I can represent a half image/text to show how to find out the number of cuts.
Here is a "stick" that has been cut into 6 parts.
_ _ _ _ _ _
If you count the number of cuts in the "stick", you can tell it is 5 cuts, which is one less than 6. Let's try cutting a stick into 11 parts now.
_ _ _ _ _ _ _ _ _ _ _
As you can see, there are 10 cuts in the "stick". Therefore, you can use the equation, x-1 = amount of cuts, where x represents the number of parts the stick has been cut into.
The final answer:
5 cuts
10 cuts
x-1

Show your work and write your answer on the line in the space below.
9514 1404 393
Answer:
18 in
Step-by-step explanation:
The volume of each container is the product of its dimensions:
V = LWH
We can let h represent the unknown height of Container 2. The volumes are equal when ...
32·18·12 = 24·16·h
(32·12·18)/(16·24) = h =18 . . . . . divide by the coefficient of h, simplify
The missing height of Container 2 is 18 inches.
