-3x =21
1/3x =6
-1/2x =-7

Answers

Answer 1
-3x = 21
Divide -3 from both sides and you get x = -7

1/3x = 6
Divide 1/3 from both sides and you get x = 18

-1/2x = -7
Divide -1/2 from both sides and you get x = 14 (you get a positive answer from 2 negatives)

Dividing 1/3 is just multiplying by 3, and dividing -1/2 is just multiplying by -2

invests $8,000 in a savings plan that pays 5% per year. What will the account balance be at the end of the first year?

Answers

The equation is I = PRT where I is the interest to, P is the principal, or money deposited, R is the rate in decimal form, and T is time in years.

I = (8,000)(0.05)(1)
I = $400

Add that to the original deposit and you have $8,400 as the account balance at the end of the first year

Answer:

3

Step-by-step explanation:

Instead of dividing, Kaitlyn multiplied both sides by 5. Divide both sides by 5 to get the y by itself and you get 3

Answer:

y=3

Step-by-step explanation:

She assumed y=75, but if y=75 then you would multiply 75×5 and that doesn't equal 15. To find y you would need to divide 5 from both sides. Therefore 15÷5 would be equal to y=3. Hope this helps!

Step-by-step explanation:

Leon constructed a point P that divides the directed segment from A to B in the ratio 2 to 1. Chelsea constructed a point Q that divides the directed segment from B to A in the ratio 1 to 2. How are points P and Q related? Explain.

Points P and Q are...

A.) two units apart. B.) the same point. C.) one unit apart.

Point P is ___ of the distance from A to B. [ A.) 2/3 B.) 1/2. C.) 1/3. ]

Point Q is of the distance from B to A. [ A.)1/3 B.). 1/2 C.)2/3. ]

The means the points lielocation along the line segment.

[ A.) At the same B.)At a different

Solution:

Since point P is divides the segment from A to B in the ratio 2 to 1 therefore:

P = 2/3 of the distance from A to B.

Since point Q is divides the segment from B to A in the ratio 1 to 2, therefore:

Q = 1/3 of the distance from B to A

2/3 of the distance from A to B = 1/3 of the distance from B to A

Therefore point P and point Q lie along the same line segment from A to B (or B to A) and the points P and Q are at the same point,

will received a 2% increase in pay, He was making $1,190/biweekly.
a. How much was his raise?
b. How much is he making now?

Answers

Answer:

A: His raise was $23.8

B: He is making $1213.8

Step-by-step explanation:

Do 1190 divided by 100 and your answer will be

11.9 which is 1%, then do (11.9 + 11.9) + 1190 which will equal 1213.8

a. Will's raise was the amount of $23.80. b. Will is now making $1,213.80 biweekly.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

Will receive a 2% increase in pay, He was making $1,190/biweekly.

a. Will's raise was $23.80. This can be calculated by multiplying his original biweekly payments of $1,190 by 2% (0.02).

b. Will is now making $1,213.80 biweekly. This can be calculated by adding his raise of $23.80 to his original biweekly payments of $1,190.

Which of the following functions has a factor of x−7?
f(x)=x3−16x2+53x+63
f(x)=x3−2x2−73x−70
f(x)=x3−16x2+53x+70
f(x)=x3−2x2−73x−77

Answers

According to the question, the function that has a factor of x - 7 is f(x) = x³ - 16x² + 53x+ 70

If x - a is a factor of a function f(x), then f(a) = 0

For x - 7 to be a factor of f(x), f(7) must be equal to zero.

For f(x) = x³ - 16x² + 53x+ 70

f(7) = 7³ - 16(7²) + 53(7) + 70

f(7) = 343 - 16(49) + 53(7) + 70

f(7) = 343 - 784 + 371 + 70

f(7) = 0

Since f(7) = 0 for f(x) = x³ - 16x² + 53x+ 70, x - 7 is a factor of f(x) = x³ - 16x² + 53x+ 70

A company claims that their new bottle holds 25% more laundry soap. If their original container held 42 fluid ounces of soap, how much does the new container hold?
The new container holds ___ fluid ounces.
HELP PLEASE. <3.

Answers

Answer:

52,5

It holds 10.5 more laundry soap

Two ways to look at this. Either way, we convert 25% to a decimal by dividing by 100, = 0.25

One way is to multiply 42 x 0.25 = 10.5. That tells us how many ounces are added. Then add 42 + 10.5 = 52.5 ounces

The other way is to multiply 42 x 1.25 = 52.5
In this equation, the 1 represents the original 42 oz, and the .25 represents the extra ounces.

6. What is the measure of ∠3? Explain.


Write your answer in the space below.

Answers

For question 1 and 2, you should keep in mind that the sum of all angles in a triangle is 180°. 1. If the measure of one angle of a triangle is 90 degrees, you can assume that the sum of the other two triangles should be 90 degrees. Because

180 - 90 = 90

The sum of the three angles of any triangle is equal to 180 degrees.

Angle 2=127 because 180-53=127.

Angle 3=23 because 180-30-127=53

Angle 1=37 because 90-53=37

Angle 4=90

Angle 1+4=127

The measure of ∠1 is 125° .

Next x+64=110. The reason why you can do this is because ∠R is going to be an opposite interior angle. Subtract 64 from the left and right sides. x=46
