Answer:
5 per minute
Step-by-step explanation:
Answer:
The person ate 5 pies per minute
Step-by-step explanation:
If 12 pies were eaten in 60 minutes , you must divide the denominator (60) by 1 (the per minute). Whatever you do to the bottom, you must do to the top, so 60 / 12 is 5.

2 (3x - 5) + 4 = -18
Solve for 20 Points
Answer:
x = -2
Step-by-step explanation:
2(3x - 5) + 4 = -18
Distribute the 2
6x - 10 + 4 = -18
6x - 6 = -18
Add 6 to both sides
6x = -12
Divide both sides by 6
x = -2
Check:
2(3x - 5) + 4 = -18
substitute x = -2 into the original equation
2(3(-2) - 5) + 4 = -18
2(-6 - 5) + 4 = -18
2(-11) + 4 = -18
-22 + 4 = -18
-18 = -18
So x = -2 is true.
Answer:
x=-2
Step-by-step explanation:
2(3x-5)+4=-18
We move all terms to the left:
2(3x-5)+4-(-18)=0
We add all the numbers together, and all the variables
2(3x-5)+22=0
We multiply parentheses
6x-10+22=0
We add all the numbers together, and all the variables
6x+12=0
We move all terms containing x to the left, all other terms to the right
6x=-12
x=-12/6
x=-2

A cube with a volume of 64 cubic meters is scaled by a factor of 5. What is the volume of the
modified cube in cubic meters? (Note: do not include the units in your answer.)
Clear
X Incorrect. When the sides of the cube are scaled by a factor of k = 5) the volume increases
by a factor of k = 52 = 125. Here, the new volume is 64 cubic meters 125 = 8,000 cubic

She got a potato I'm peelin it
Answer:
1. Vertical angles. X = 128º
2. The two angles labeled make up a linear pair & are supplementary, meaning they add up to 180º.
So:
7x + (x+20) = 180
Solve for x:
7x + (x + [20-20]) = 180 - 20
7x + (1)x = 160
8x = 160
X = 20
3. The two angles are complementary, meaning they add up to 90º.
So:
X + 35 = 90
Solve for x:
X + (35-35) = 90 - 35
X = 55
4. the two angles are complementary, and add up to 90º.
So:
4x + 2x = 90
Solve for x:
6x = 90
6x/6 = 90/6
X = 15.
5. Vertical angles, so they are equal in measure.
So:
75 = 4x - 25
Solve for x:
75 + 25 = 4x (-25 + 25)
100 = 4x
100/4 = 4x/4
X = 25.
6. The 3 angles all add up to 180º. they are supplementary.
So:
75 + x + (3x + 5) = 180
Solve for x:
(75 - 75) + x + (3x + 5) = 180 - 75
X + (3x + 5) = 105
X + 3x + (5-5) = 105 - 5
(1) x + 3x = 100
4x = 100
4x/4 = 100
X = 25
7. The 2 angles shown in the picture add up to 180º & are supplementary.
So:
x + (2x - 21) = 180
Solve for x:
X + (2x [-21 + 21]) = 180 - 21
(1)x + 2x = 159
3x = 159
3x/3 = 159/3
X = 53.

What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
There are two children in the Patel family.
They are twins of the same age.
Let x be the age of two children.
As they are twins so the age of children's is same.
The formula of range is highest minus lowest.
range = highest - lowest
Range=x - x
Range =0

Sally would like to have an average of 92 in her math class. She has completed four assignments with the following grades: 88, 97, 91, 86. What is the lowest grade Sally will need to make on the last assignment to meet her goal?
Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5
This would get of / 5 so you don't need to divide by 5
362 + x = 460
Subtract 362 from each side
x = 98

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place
Step-by-step explanation:
I think you have forgotten to attach the question.
Anyways....
In order to find the area of a circle use the formula:
π[tex]r^{2}[/tex] Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × [tex]3^{2}[/tex]
Since you have taken pi as 3.142...
3.142 × [tex]3^{2}[/tex]
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.
= 28.3 [tex]cm^{2}[/tex]

Two brothers went shopping at a back-to-school sale where all shirts were the same price, and all the shorts too. The younger brother spent $230 on 8 new shirts and 10 pairs of shorts. The older brother purchased 8 new shirts and 4 pairs of shorts and paid a total of $116. How much did each item cost?
Answer:
Younger: 12.78 per item
Older: 9.67 per item
Step-by-step explanation:
Well, if all the shirts and shorts were the same price divide the total price and total amount of items they bought.
Younger Brother:
8 shirts + 10 shorts = 18 items for $230
$230 ÷ 18 items = about 12.78 per item (it comes out to a lot of number so I estimated it the nearest hundredth)
Older Brother:
8 shirts + 4 shorts = 12 items
$116 ÷ 12 items = about 9.67 per item (estimated again)

An area cannot be in feet. It must be in a square unit such as square feet.
A = r²
A = ()(3 ft)²
A = 9 ft²
A = 9(3.14159) ft^2 = 28.3 ft²

Harry spends
of his salary and saves the rest of his salary

the amount of salary Isabel saves: the amount of salary she spends = 3:-
Work out who saves the most of their salary each month.
You must show how you get your answer.
Answer:
isabel saves the most of their salary each month
Step-by-step explanation:
Let us assume the Salary of Gavin, Harry & Isabel be $100
Since
Gavin saves 28%
So his saving amount is Gavin
= 28% of $100
= $28
As harry spends 3 ÷ 4 of his salary
So Harry Spenings is
= (3 ÷ 4) of $100
= $75
Now
Harry Saving is
= $100 - $75
= $25
Also the ratio between isabel saves, and spend is 3:7
3k + 7k = 10k = 100S
k = $10
Now
the amount of salary isabel saves
= 3k
= 3 × $10
= $30
Now
$30 > $28 > $25
i.e.
isabel Saving > Gavin Savings > Harry Savings
Hence, isabel saves the most of their salary each month
