Answer:

m=-5

Step-by-step explanation:

Simplifying

5m + -6 = 8m + 9

Reorder the terms:

-6 + 5m = 8m + 9

Reorder the terms:

-6 + 5m = 9 + 8m

Solving

-6 + 5m = 9 + 8m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-8m' to each side of the equation.

-6 + 5m + -8m = 9 + 8m + -8m

Combine like terms: 5m + -8m = -3m

-6 + -3m = 9 + 8m + -8m

Combine like terms: 8m + -8m = 0

-6 + -3m = 9 + 0

-6 + -3m = 9

Add '6' to each side of the equation.

-6 + 6 + -3m = 9 + 6

Combine like terms: -6 + 6 = 0

0 + -3m = 9 + 6

-3m = 9 + 6

Combine like terms: 9 + 6 = 15

-3m = 15

Divide each side by '-3'.

m = -5

Simplifying

m = -5

Answer:

A. The rectangular prism will have a perimeter of 32 centimeters along the base.

Step-by-step explanation:

When your looking for perimeter, you don't use the height, however, you have to take into account the half sized cubes, in order to get an accurate perimeter, you have to multiply everything by it's multiplicative inverse in order to fill everything with the cubes. Thus, the first option makes the most since you have to double the height and length, when you do so, you get 10 10 6 and 6. You then add them together to get 32.

I really hope this makes since and that I didn't get it wrong. Have a good day and Good luck!

Answer:

Perimeter of a square=circumference of circle

4×22=2πr

44=πr

r=14

Area of circle=πr2

22/7×14×14

28×22

616

Answer:

176cm²

Step-by-step explanation:

Side of square = 22cm

Perimeter of square = 88cm

Circumference of circle = perimeter of square

2π r = 88cm

2 x 22/7 x r = 88cm

44/7 x r = 88cm

r = 88 x 7/44

r = 14cm

Area of circle = π x r x r

= 22/7 x 14 x 14

= 44 x 4

= 176 cm²

Answer: i will give you the first couple answers and how i got it you do the rest yourself. You need to combine like terms so add or subtract only the same numbers with the same sign. if the sign has no number imagine an invisible 1 before it. so for example the first one would be (4A) all i did was add the A together to get that i will also give you the last answer for another example. the problem is  20-9z+4y+7-x. all you gotta do is add 7 to  the 20  add -9+-x and leave the 4y alone since there is no other y the answer would be 27-10z+4y+

The perimeter of a rectangle with x cm width and (x = 2) cm length is

(4x + 4) cm.

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

We know the perimeter of a rectangle is 2(length + width).

Given, The width of a rectangle is x centimeters and its length is (x+ 2) cm.

So, the expression for the perimeter of the given rectangle is

2(x + (x + 2)) cm.

= 2(2x + 2) cm.

= (4x + 4) cm.

At this hourly rate, the employee earns a 40-hour workweek is D.$320.00

In the above case, an employee earns $72.00 for working 9 hours a day or 9 hours, now to know about hourly earing we should divide $72.00 by 9 hours so that we can get the earnings of the employee on an hourly basis.

Therefore, earnings an hour = 72.00/9 = 8, which means the employee is earning 8 dollars for every hour he works at the gift shop, now to know how much money he/ she will generate in 40 hours we will multiply 8 dollars with 40 working hours.

Therefore total earnings of the week =  earning per hour * total working hours = 8*40 = $320.00 for every 40-hour week. hence, the total earnings for the week will be $320,

Calculations

earning per hour =72.00/ 9 = 8

total earning = 40*8 = 320

correct option will be D. $320

Answer:

450

Step-by-step explanation:

Formula = Number x 100

Percent = 81 x 100

18 = 450

Following shows the steps on how to derive this formula

Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.

81

18% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

18Y = 81 x 100

18Y = 8100

Y = 8100

100 = 450

Answer:
