I don’t quite understand what it means im stuck between multiplication and Like Terms. Can someone please help me?

Answers

Multiplication is when you times two different numbers together where its negative or postive(you can multiple pretty much anything together)but combining like terms are number or letters thats the same. For instance, say if i have 4x+7-2x+3, i would combine each term that has something in common with it,like, 4x and 2x because both has X and i will combine 7 and 3 because those two are regular numbers and does not have an X like the others. I Hope That helps!

Is (6/5, 2) a solution to y = x + 4/5​

Answers

Answer:

Yes, it is.

Step-by-step explanation:

y = x + 4/5

2 = 6/5 + 4/5

2 = 10/5

2 = 2

Two equals two.

No, it is not. We know ordered pairs go like this: (x, y). If x is equal to 6.5, then we can do 6.5 + 4.5, which equals 11. If x is 6.5, then y should be 11, not 2.

Question is given in picture below. Help will be greatly appreciated!

Answers

Answer:

C

Step-by-step explanation:

Th explicit formula of a geometric sequence has the following format:

[tex]x_n=a(r)^{n-1}[/tex]

Where a is the initial term and r is the common ratio.

From the recursive formula, we can see that each subsequent term is multiplied by 13. Thus, the common ratio is 13.

Also, we are given that the first term is 7.

So, substituting these in, we have:

[tex]x_n=7(13)^{n-1}[/tex]

Our answer is C

And we're done!

A new Youth Activity Center is being built in Hadleyville. The perimeter of the rectangular playing field is 430 yards. The length of the field is 5 yards less than quadruple the width. What are the dimensions of the

playing field?

The width is yards.

The length is yards.

Answers

Answer:

Width = 44 yards

Length = 171 yards

Step-by-step explanation:

Given:

Perimeter of the rectangular field = 430 yards.

Let:

The length of the field be L

The width of the field be W.

From the question:

The length of the field is 5yards less than quadruple the width. This implies that;

L = 4W - 5

But.

Perimeter (P) of a rectangle is given by:

P = 2(L + W)       ---------------(i)

Substitute the values of P = 430, L = 4W - 5 and W into equation (i) as follows;

430 = 2(4W - 5 + W)

430 = 2(5W - 5)

430 = 10W - 10

10W = 430 + 10

10W = 440

Divide both sides by 10

W = 44

Therefore, the width of the field is 44 yards.

Remember that,

L = 4W - 5          

[Now substitute W = 44]

L = 4(44) - 5

L = 176 - 5

L = 171

Therefore, the length of the field is 171 yards

Answers

Answer:

x = 3

Step-by-step explanation:

Step 1: Write out equation

x + 9 = 18 - 2x

Step 2: Add 2x on both sides

x + 2x + 9 = 18 - 2x + 2x

3x + 9 = 18

Step 3: Subtract 9 on both sides

3x + 9 - 9 = 18 - 9

3x = 9

Step 4: Divide both sides by 3

3x/3 = 9/3

x = 3

PLEASE HELP ASAP!! Ben worked 6 hours at x dollars per hour. Julie worked 9 hours and earned twice as much as Ben per hour. Phil worked 16 hours and earned 3 dollars an hour less than Julie. Choose the expression that is correctly simplified and best represents their total wages. A. 56x – 48 B. 40x – 48 C. 31x – 3 D. 40x – 3

Answers

Answer:

A

Step-by-step explanation:

Given that Ben worked 6 hours at x dollars per hour. That is,

Ben earns = 6x

Julie worked 9 hours and earned twice as much as Ben per hour. That is,

Julie earns = 9 × 2x = 18x

Phil worked 16 hours and earned 3 dollars an hour less than Julie

That is,

Phil earns = 16 × ( 2x - 3 )

= 32x - 48

Total wages = 6x + 18x + 32x - 48

Total wages = 56x - 48

The bells are adding a new room to their house. The room will be a cube with volume of 4,913 feet cubed. They are going to put in hardwood floors, and the contractor charged $5 per square foot. How much will the j hardwood floors cost?

Answers

Answer:

  $1445

Step-by-step explanation:

The side length of the room is the cube root of the volume of the cube:

  s = ∛4913 = 17 . . . . feet

The area of the floor is the square of this side length:

  A = (17 ft)² = 289 ft²

The cost of the floor is $5 for each square foot:

  cost = ($5/ft²)(289 ft²) = $1445

The hardwood floor will cost $1445.

Min-jun has a swimming pool that needs to be drained. His pool holds
10,874.5 gallons of water and will need to drain completely in 10.7
hours. What is the change in the water level per hour for Min-jun's
swimming pool? Round your answer to the nearest hundredth.

Answers

You will need to drain 1016.308 gallons an hour

Answer:

The change in the water level per hour for Min-Jun's swimming pool is 1016.31 Gallons per hour.

Step-by-step explanation:

Since we have a total amount of 10,874.5 gallons and 10.7 hours total to drain the full pool we divide the total amount by the total time, assuming that the pool drains at a constant rate. When we divide 10,874.5 by 10.7 we get 10.16.3084... and rounding it to the nearest hundreth or the second decimal place we get 1,016.31 gallons per hour.

An adult usually has 32 teeth. People sometimes lose some of their teeth. Pat has only 5/8 of her teeth left. How many teeth has she lost?

Answers

Answer:

twenty teeth

Step-by-step explanation:

4•5=20

Answer:

Pat has lost 12 teeth.

I got a calculator and divided 32 by 8, then timed that answer (4) by 3.

32 ÷ 8 = 4

4 x 3 = 12

If the question had asked how many teeth Pat has, the answer would be 20, but that isn't correct for this question. It asks how many teeth she has lost, and that would be 12.
