Step-by-step explanation:

Find the values of x and y

Answers

Answer:

x = 8

y = 21

Step-by-step explanation:

The angle (7x + 12)° and the angle (12x-28)° are alternate interior angles and so has got the same measurement

7x + 12 = 12x - 28

12 + 28 = 12x - 7x

40 = 5x divide both sides by 5

8 = x

The sum of angle (12x - 28)° and (9y - 77)° must be equal because they make a straight line with the measure of 180°

12x - 28 + 9y - 77 = 180 we already found the value of x as 8 so let's rewrite the equation

12 × 8 - 28 + 9y - 77 = 180

96 - 28 - 77 = 180 add like terms

9y - 9 = 180

9y = 189 divide both sides by 9

y = 21

The school bought a new computer for me for $960. If that is 120% of what
the store paid for it, how much did the store pay for it?

Answers

Answer:

The store paid $800 for it

Step-by-step explanation:

let x be the value the store paid for it

120/100 * x = 960

120x = 96000

x = 96000/120

x = $800

d) n = -3.2

Thank you..

Answers

Answer:

(A) and c

(B) and a

(D) and b

Step-by-step explanation:

these are from the calculations i got, what you do is minus the two answers you have to find n

For equations,

A) -1.4 n + 2.1 = 6.58 then n = 3.2

B) 4 n - 2 3/4 = -22 3/4 then n=24

C) 5.7 n + 4.1 = 2.96 then n=-0.2

D) n/8 + 1/2 = -3 1/2 then n=24

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

A) -1.4 n + 2.1 = 6.58

Subtract 2.1 on both sides

1.4n=6.58-2.1

1.4n=4.48

Divide both sides by 1.4

n=3.2

B) 4 n - 2 3/4 = -22 3/4

4n-11/4=-85/4

4n=85/4+11/4

4n=96

Divide both sides by 4

n=24

C) 5.7 n + 4.1 = 2.96

5.7 n = 2.96- 4.1

5.7n=-1.14

n=-0.2

D) n/8 + 1/2 = -3 1/2

n/8 = -3 1/2-1/2

n/8 = -5/2-1/2

n/8 = -3

n=-24

Hence, equations A) -1.4 n + 2.1 = 6.58 then n = 3.2

B) 4 n - 2 3/4 = -22 3/4 then n=24

C) 5.7 n + 4.1 = 2.96 then n=-0.2

D) n/8 + 1/2 = -3 1/2 then n=24

What is the mean?

Answers

15.25, you add them all together which would equal 61 and then divide by 4 since there’s 4 numbers

Answer:

The mean is 15.25.

Step-by-step explanation:

First, we need to be sure we know that the mean is the average number in the group of numbers. That doesn't mean the most repeated or the number in the middle. Simply, the average.

To find the mean of a group of numbers you simply add them all together and divide by the number of numbers. So, let's solve.

12 + 14 + 17 + 18

= 61 ÷ 4

= 15.25

So the mean of 12, 14, 17, and 18 is 15.25.

15/ 25

Step by step explanation

With exponents you don’t multiply them by the number you multiply them the amount of times the number says so if a is one you multiply 1×1×1 which is one then you move on to B both times has it exponent of 2 so 3×3 is nine and 9×1 is 10. And since there is no exponent Over C, you can just add 10+5 which is 15

Now on the bottom half you see that C doesn’t have an exponent so we can figure out a is 1 then, do you see that b has the same exponent of two we are just going to bring that nine down to the lower half now as you can see, C has an exponent 5×5×5 is 15 and 15+10 = 25
