Answer:

n=-6

Step-by-step explanation:

8n-7=-5(-3n-7)

Multiply -5 to -3n and -7

8n-7= 15n+35

Bring 8n to the other side by subracting it from 15n

-7=7n+35

Subtract 35 from both sides

-42=7n

Divide both sides by 7

n=-6

Answer:

t =30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles.

t + (2t-28) = t+32

Combine like terms

3t -28 = t+32

Subtract t from each side

3t -28-t = t+32-t

2t -28 = 32

Add 28 to each side

2t-28+28 = 32+28

2t = 60

Divide by 2

2t/2 = 60/2

t =30

Answer:

30$

Step-by-step explanation:

lets assume you didn't have a coupon then the total bill would have been 120$

so for 4 friends including u the bill would have been 120$

: 4 friends = 120 $

for : 1 friend = x$

cross multiply

4x = 120 × 1

4x =120

divide both sides by the coefficient of x

x =120 \ 4

x = 30$

therefore: 1 friend = 30$

Answers: The page numbers are 11 and 12

==========================================================

Explanation:

Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.

Let,

Adding those two said pages will lead to 23

first + second = 23

(x) + (x+1) = 23

2x+1 = 23

2x = 23-1

2x = 22

x = 22/2

x = 11 is the first page

x+1 = 11+1 = 12 is the second page

Check: 11+12 = 23 which confirms the answers.

Answer:

x=5

Step-by-step explanation:

Since the two angle are corresponding, they have equal measure

therefore, 22x=110

now that we have produced an equation, solve for the value of x

22x/22 = 110/22

x=5

hope this helps :)

Answer:

22x=110° (corr angles)

x=110÷22

Answer:

x=25, y=19

Step-by-step explanation:

130+2x=180

x=25

54+2x+4y=180

y=19

Answer:

x = 25 , y = 19

Step-by-step explanation:

130° and 2x° are adjacent angles on a straight line and sum to 180° , so

130 + 2x = 180 ( subtract 130 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

--------------------------------------------------------------

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle , then

54 + 4y = 130 ( subtract 54 from both sides )

4y = 76 ( divide both sides by 4 )

y = 19

Answer:

I do not understand she question do you mean the sum of their income is 2640

if so, then the answer is 440 to be x income

Step-by-step explanation:

x income = 20% or 1/5 of y income

y income = 5 of x income

we know that the sum of their income = 2640

which means that

x + y = 2640 =

1/5y + y = 2640

6y/5 = 2640

cross multiply to give us

6y = 5(2640)

6y = 13200

divide through by 6 to give us,

6y/6 = 13200/6

y = 2200

since we know that x income is 20% y income,

therefore, x income =

20/100 * 2200

= 440

therefore,

x income = 440

y income = 2200

Find x:

Answer:

130%

Step-by-step explanation:

Use the formula for percent change: difference = % * original price

To find the difference, you have to do 299 - 130, which is 169.

The original price is $130 because this is the price before it rose to $299.

Now, you have the equation 169 = % * 130.

We don’t know the percentage right? No, so we have to find the percentage by dividing 169 by 130, which gives you 1.3. Lastly turn 1.3 into a percentage by multiplying 1.3 by 100, and 1.3 as a percentage is 130%. So therefore, the percent increase is 130%.

130%

Step-by-step explanation:

Yesterday = $130.

Today = $299 .

((final price - initial price)/(initial price)) × 100%

= (($299 - $130)/$130) × 100%

= ($169/$130) × 100%

= $1,3 × 100%

= 1,3 × 100%

= 130%

Answer:

obtained number divided by total number multiply by 100%.

· Definition of Percentages

Mathematically, percentages are either numbers or ratios that are expressed as fractions of 100. They are usually denoted as "%" or simply "percent." They may be further represented as simple fractions or as decimal fractions. An example of a percentage is 65% or 65 percent.  The term percentage was formed from two words, “per” and “cent.” Cent is a word with Latin and French origin that means "hundred," and "percent" means "per hundred." For example, 90 percent (or 90%) means 90 out of 100 while 50 percent (or 50%) means 50 out of 100 or half of a whole.

1. Determine the initial format of the number to be converted to a percentage

The number to be converted to a percentage can either be in the decimal or fraction format. A good example of a decimal number is 0.57, which may be the calculated ratio of the values you are comparing, while an example of a fraction is 3/20. The initial format will determine the next mathematical process to be carried out on the number.

2. Carry out a mathematical process on the number to be converted to a percentage

If the number to be converted to a percentage is a decimal number like 0.57, you may not need to do anything to it before you go to the next step. However, if it is a fraction like 3/20, you should first divide the numerator (3 in this case) by the denominator (20 in this case) to get a decimal number.

3. Multiply the result of the mathematical process by 100

If you are required to convert a decimal number like 0.57 to a percentage, you are to simply multiply it by 100. That is, 0.57 x 100 = 57. Therefore, 0.57 as a percentage = 57% or 57 percent. Another example of converting a decimal to a percentage is 0.03 x 100 = 3% or 3 percent.

However, if you are required to convert 3/20 to a percentage, you should divide 3 by 20 = 0.15. Then multiply 0.15 by 100 = 15% or 15 percent.

Another example is if you are to convert 5/10 to a percentage, you should divide 5 by 10 = 0.5. Then, multiply 0.5 by 100. Therefore, 0.5 x 100 = 50% or 50 percent.

Answer:

30

Step-by-step explanation:

16/54 as a percentage is 29.6296%. round up to get the nearest whole number.

29.6296 rounded up is 30

Answer:

16 = 30% of 54

Step-by-step explanation:

16/54 =x/100

(16/54)(100%) = x

(0.296)(100%) = x

29.6% = x

30% = x

So for the coorfinates of F, you have to see how far it is from y=1. The F is 2  points under the 1 so you have to count 2 above the 1. So the point would be (7,3). Same for the other ones. For example like D. It's 2 above 1 so its going to be 2 under which would result in (1, -1)

Answer:

Chelsea can make 3 [tex]\frac{1}{2}[/tex] batches of icing with 7/8 pounds of butter.

Step-by-step explanation:

7/8 ÷ 1/4  (reciprocate 1/4 to replace division sign with multiplication sign)

= 7/8 x 4/1

= 28/8

= 7/2

= 3 [tex]\frac{1}{2}[/tex]

This means that Chelsea can make 3 [tex]\frac{1}{2}[/tex] batches of icing with 7/8 pounds of butter.
