don't get mad if im wrong lol I tried
How to Solve:
So first start with the parentheses, which just rewrites the problem too -4+3n-5-7n. Next, you want to add like terms, so it becomes -9-4n! If you don't know like terms are anything variable that matches, for example, 7n & 3n! Along with -4 & -5!

Answer:
8(x+3)
Step-by-step explanation:
When you distribute the 8 to the x, it will become 8x.
when you distribute the 3 to the 8 (multiplying them) you will get 24.
Then that will make the original equation.

Answer:
The answer is $19.44
Step-by-step explanation:
First, set up a proportion for tax and tip.
Your proportion should be x (the variable) over 28.80, equal to 25 over 100.
Then, cross multiply to set up an equation.
Your equation should be 100x is equal to 720.
Solve the equation by dividing both sides by 100, getting the amount for your variable, x, which should be $7.20.
Next, subtract $7.20 from the original price of 28.80, getting $21.60.
Next, set up the same proportion, except make it so that x is over $21.60 and 10 is over 100.
Cross multiply and set up your equation which is 100x is equal to 216.
Solve the equation by dividing both sides by 100, getting the value if x as $2.16.
Finally, subtract $2.16 from the sale price of $21.60, giving you your answer of $19.44.

Marta is solving the equation S = 2πrh + 2πr2 for h. Which should be the result?
StartFraction S Over 2 pi r EndFraction equals h. – r = h
StartFraction S minus r Over 2 pi r EndFraction equals h. = h
S – S minus StartFraction r Over 2 pi EndFraction equals h. = h
S – S minus StartFraction 2 pi Over r EndFraction equals h. = h
Answer:
Step-by-step explanation:
Only the term 2πrh contains h. Isolate this term on the right by subtracting 2πr^2 from both sides:
S - 2πr^2 = 2πrh
Now divide the left side by 2πr, obtaining:
s - 2πr^2
h = ------------------
The equation S = 2πrh + 2πr² to solve for h is as follows:
h = S - 2πr² / 2πr
How to find the subject of formula in an equation
S = 2πrh + 2πr²
We want to make h the subject of the formula,
Therefore,
S = 2πrh + 2πr²
subtract 2πr² from both sides
S - 2πr² = 2πrh
divide both sides by 2πr
Therefore,
S - 2πr² / 2πr = 2πrh / 2πr
Hence,
h = S - 2πr² / 2πr

Simplifying by combining like terms. 2 3/4c + 3 1/8c + 7
Please help!:)
Answer:
5 7/8 c + 7
Step-by-step explanation:
2 6/8 c + 3 1/8 c + 7
5 7/8 c + 7
Answer:
5 7/8c + 7
Step-by-step explanation:
2 3/4 c and 3 1/8c can be combined because they both have the same variable.
7 cannot be combined because it does not have a variable.
2 3/4c + 3 1/8c = 5 7/8c
therefore leaving the equation to be simplified from 2 3/4c + 3 1/8c +7 to

Barbara plotted an elevation below sea level on a number line and labeled it A. She plotted Point B above 0, a distance that is exactly as far from 0 as Point A is. Explain what you know about Point B.
According to Barbara's plot, the number line A, is above sea level, therefore, it's a positive line, in positive range.
On the other hand, the number line B has the same distance but in the opposite direction, is downwards the zero point. So, this means the B line is below sea level, because is in positive range. That's what we can deduct from this, because the characterization Barbara is doing is related to sea level.

At a deli counter, someone buys: 1 3/4 pounds of ham for $14.50, 2 1/2 pounds of turkey for $26.25, and 3/8 of a pound of roast beef for $5.50. Which deli meat is the least expensive per pound?
Ham
Change each mixed numeral or fraction into a decimal number, and divide each price by its weight.
Ham: ($14.50)/(1 3/4 lb) = $14.50/(1.75 lb) = $8.29/lb
Turkey: ($26.25)/(2 1/2 lb) = $26.25/(2.5 lb) = $10.50/lb
Roast beef: ($5.50)/(3/8 lb) = $5.50/(0.375 lb) = $14.67/lb
The least expensive per pound is ham.
The deli meat is the least expensive per pound is ham meat costing $8.29 per pound
Cost per poundGiven:
Cost of 1 3/4 pounds of ham = $14.50
Cost per pound = 14.50 ÷ 1 3/4
= 14.50 ÷ 7/4
= 14.50 × 4/7
= 58/7
= $8.29 per pound
Cost of 2 1/2 pounds of turkey = $26.25
Cost per pound = 26.25 ÷ 2 1/2
= 26.25 ÷ 5/2
= 26.25 × 2/5
= 52.5/5
= $10.5 per pound
cost of 3/8 of a pound of roast beef = $5.50
Cost per pound = 5.50 ÷ 3/8
= 5.50 × 8/3
= 44/3
= $14.67 per pound

In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40-degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y. (5 points)
60° + 70° + y° = 180°
130° + y° = 180° ~Subtract 130° from both sides
y° =50°
y=x because they are both vertical angles
x° = 50°
Answer:
40 + 50 + y = 180
90 + y = 180
90 - 90 = 0
180 - 90 = 90
y = 90
Help me please i don’t understand
Answer:
90
Step-by-step explanation:
There are 10 red candies, 18 green candies, 9 yellow candies, and 13 brown candies.
10 + 18 + 9 + 13 = 50.
There is a total of 50 candies. Out of the 50 candies, 18 are green.
[tex]\frac{18}{50} \\[/tex]
You have to get to 250 .That means you do [tex]\frac{18}{50} = \frac{x}{250}[/tex]
250 divided by 50 = 5.
18 x 5 = 90.
Therefore, she can expect 90 green candies
