Answer:
z=-3
Step-by-step explanation:
Answer:
z=3
Step-by-step explanation:
42=−7(z−3)
Simplify both sides of the equation.
42=−7(z−3)
42=(−7)(z)+(−7)(−3)(Distribute)
42=−7z+21
Flip the equation.
−7z+21=42
Subtract 21 from both sides.
−7z+21−21=42−21
−7z=21
Divide both sides by -7.
-7z/-7=21/7
z=3

4/5 + v = 41/20
solve this plz and show me how you got the answer
Answer:
v = 1 1/4 (1.25)
Step-by-step explanation:
4/5 + v = 41/20
16/20 + v = 41/20
16/20 16/20
---------------------------
v = 41/20 - 16/20 = (41-16)/20 = 25/20 = 5/4 = 1 1/4

A community garden center host a plant giveaway every spring to help community members start there gardens. Last year the give away supported 50 families by giving away 150 plants. Based on this ratio hawa many plants will they give away this year in order to support 65 families
Answer:
195 plants (verified) ✅Step-by-step explanation:
We will use a proportion to solve this.
x/y = x/y
let x = the number of families in each case
let y = the number of plants in each case
Since we don't know the second y, we will leave that as y and solve for it.
50/150 = 65/y
Cross-multiply
50y = 9750
Divide
195 = y
Now, we can check this by substituting the value of y back into the equation and seeing if both sides equal.
50 (195) = 9750
9750 = 9750 ✅

George lost 12 1/4 kilograms on his diet. How
many grams did he lose?
Answer: 12250 Grams
Step-by-step explanation:
1 Kilogram = 1000 grams.
12 Kilograms x 1000 Grams = 12000 Grams.
1/4 = 0.25
0.25 Kilograms x 100 Grams = 250 Grams
12000 + 250 = 12250.
Answer: 12250 Grams.

Answer:
A. Store A will cost about $1.28 less
Step-by-step explanation:
Store A:
Unit rate = y/x
Using any given pair, say (3, 7.26),
Unit rate = 7.26/3 = $2.42 per gallon
So, of a customer is buying 16 gallons at Store A, he'd pay:
$2.42 * 16 = $38.72
Store B:
Unit rate = y/x
Using any point on the graph, say (20, 50),
Unit rate = 50/20 = $2.5 per gallon
So, of a customer is buying 16 gallons at Store B, he'd pay:
$2.5 * 16 = $40.
Cost of Store B - Cost of Store A = $40 - $38.72 = 1.28
This means that Store A cost about $1.28 less

A community drama centre sells tickets to a play. They sell 216 tickets. Adult tickets cost $10.25 and students tickets cost $8. The total number of sales was $2117.25. How many students tickets were sold, how many adult tickets were sold?
Please show me how its done
Will make brainlist, thanks
Answer:
Adult Tickets: 173
Student Tickets: 43
Explanation:
To solve this problem, you'll need to set up a system of equations.Assume a = # of adult tickets soldAssume s = # of student tickets sold2: a + s = 216; 1: 10.25a+ 8s= 2117.25
2: <<As the total number of tickets sold from both sides is equal to 216>>
1: <<Each adults ticket (a) costs $10.25 and each student ticket (s) costs $8, and the total amount of money earned (2117.25) from sales is the combination of these two))>>
Note that there are two ways to solve systems of equations (by elimnation and substitution), in this case I'll use elimnation as substitution requires one of the variables in one of the two equations to be isolated.In this case, I'll elimnate a.a + s = 216
10.25a + 8s = 2117.25
In order to elimnate a, it has to be equal to - 10.25 so that it cancels out + 10.25 (so you have to multiply everything on the first equation by 10.25 ((what you do to one part, you'll do to all the other parts)).-10.25a -10.25s = -2214
10.25a + 8s = 2117.25
a cancels, and now you solve accordingly.-2.25s/-2.25 = -96.75/-2.25
s = 43
You could solve for a using this same method, but it's easier to use the first formula <<a+s=216>> to find a.a + 43 = 216
- 43 -43
a = 173
4(3+c)+c=c+4 ???????????????????????????
Answer: = - 2
Step-by-step explanation:
Answer:
28
Step-by-step explanation:
4(3+4) so you do multiplication because there is a parenthesis and you do the 4 multiply the number that is inside the parenthesis so 4x3 + 4x4 you do that and then multiply it then we will have 12+16 and we add that we get 28 and that’s the answer I hope it helps you
aron lei is making identical balloon arrangements for a party. He has 32 maroon balloons and 24 white balloons, he wants each arrangements to have the same number of each color. what is tha greatest number of arrangements that he can make if every balloon is used?
Answer:
The greatest number of arrangements that he can make if every balloon is used is 8.
Step-by-step explanation:
The greatest number of arrangements will be the greatest common factor between 24 and 32.
GCF of 24 and 32:
We keep factoring both numbers by prime factors, while they can both be divided by the same number. So
24 - 32|2
12 - 16|2
6 - 8|2
3 - 4
There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.
This means that the greatest number of arrangements that he can make if every balloon is used is 8.
What is the solution to this system

Bella needs to paint a logo made using two right triangles. The dimensions of the logo are shown below. What is the area of the two triangles that need to be painted?
Dimensions:
Triangle 1: 6 by 2
Triangle 2 5 by 9
Answer:
It would be 28.5. First, you would find the area of the smaller triangle by using the formula a=.5bh (area=.5xbasexheight) and then when you get that, you should get 6. Then, you do the same for the larger triangle and you should get 22.5. Then, 22.5 + 6 = 28.5, giving you that answer.
Step-by-step explanation:
f(x) = x + 8; translation 5 units down
Answer:
Please check the graph diagram attached.
From the diagram,
The red line represents the parent function f(x) = x + 8The blue line represents the translated function f(x) = x + 3It is clear the parent function f(x) = x+8 has been translated down 5 units.
Step-by-step explanation:
The rule to determine the translating down 'b' units:
f(x) – b
It means if we have to translate a function f(x) 'b' units down, all we need is to subtract the 'b' units from the function output.
Given the function
f(x) = x + 8
In order to translate 5 units down, all we need is to subtract 5 units from the function.
i.e.
f(x) = x + 8 - 5
f(x) = x+3
Thus, we conclude that f(x) = x+3 is the translated function.
Please check the graph diagram attached.
From the diagram,
The red line represents the parent function f(x) = x + 8The blue line represents the translated function f(x) = x + 3It is clear the parent function f(x) = x+8 has been translated down 5 units.

The average rate of change of h(t) = -16t ² + 40t + 4 between t = 0 and t = 2 is
(h (2) - h (0)) / (2 - 0) = ((-16×2² + 40×2 + 4) - (-16×0² + 40×0 + 4)) / 2
… = ((-64 + 80 + 4) - 4) / 2
… = 16 / 2
… = 8
h(t) is measured in feet, so the average rate of change is measured in feet per second, so it's 8 feet per second.
