7x+9=2x+39 i need all the steps

Answers

Answer:

Step-by-step explanation:

7x+9=2x+39

7x+9-9=2x+39-9

7x=2x+30

7x-2x=2x+30-2x

5x=30

5x/5=x

30/5=6

x=6

Answer:

X=6

Step-by-step explanation:

7x+9=2x+39

First, subtract 9 from both sides like this

7x+9 -9 =2x+39-9

equaling 7x=2x+30

Then, subtract 2 from both sides like this

7x - 2=2x -2+30

equaling 5x=30

Lastly you divide 5 from both sides like this

5x / 5 = 30 / 5

equaling x=6

A coefficient must have a multiplication sign after it. A True B False

Answers

Answer:

False

Step-by-step explanation:

Examples

The coefficient of 6x is 6. The coefficient of 19x is 19.

A coefficient is the number that is paired with a variable, but it does not need to have a multiplication sign after it in a equation.

The statement that a coefficient must have a multiplication sign after it is false

A coefficient is a number or expression that appears before a variable.

Take for instance:

The coefficient of x in 3x is 3The coefficient of y in 20y is 20The coefficient of z in 3xz is 3x

In the above samples, there is no multiplication sign after the coefficients.

Hence, the statement is false.

Cole has a rectangular garden with an area of 16.02 square meters. What is the width, in meters, of the garden?

Answers

Answer:

3.56m

Step-by-step explanation:Parameters given:

Area of the rectangular garden = 16.02m^2

Length of the rectangular garden = 4.5m

The Area of a rectangle can be calculated for using the formula below

Area (square meters) = length (meters) × width (meters)

Therefore, 16.02m^2 = 4.5m × width

Width = 16.02m^2 / 4.5m

Width = 3.56m

Therefore the width in meters of the garden is 3.56m

See the attachment below for an illustrative diagram

A = area

l = length

w = width

16.02 divided by 2 = 8.01

Ellen bought new fish for her home aquarium. She bought 4 Turquoise Guppies and 3 Sunburst Tetra GLO Fish and spent a total of $41.73. Danielle bought 3 Turquoise Guppies and 5 Sunburst Tetra GLO Fish for a total of $56.02. How much was one Turquoise Guppy.

Answers

Answer: Ellen: 4t + 3s = 41.73

Danielle: 3t + 5s = 56.02

t = $3.69 each

Step-by-step explanation:

with 4t + 3s = 41.73 and 3t + 5s = 56.02

you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get

-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get

11/5t = 8.118 then divide 8.118 by 11/5 to get

t = 3.69

Rose has $426.00 in her checking account. 1⁄3 of her money will go toward bills. How
much of her money does she have left in her checking account? DO NOT PUT UNITS!!! Only put
numbers for your final answer.

Answers

Answer:

$284

Step-by-step explanation:

First, find 1/3 of 426 by multiplying 1/3*426

With your answer (142), subtract that from the total in your checking account.

426-142=284

This means, After withdrawing the amount she will use to pay bills, Her left over total will be 284 dollars.

(1/3) * 426 = 142 < What goes towards bills.

426 - 142 = 284
What is left in her checking account is $284.

Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.

Complete the following table:

Number of friends (f) 5 10 15 20
Cost of party (c) 100 200 300 400

Plots the points from the table onto the graph.

Answers

Answer: Answer with Step-by-step explanation:

Since we have given that

Cost of party per person = $20.

Let the number of friends be 'f'.

Let the cost of party be 'p'.

According to question, our equation becomes

p= 2f

So, if p = 100, then f = p/2 = 100/2 = 50 if f = 10, then, p = 2f = 2 • 10 = 20 If p = 300 then, f = 300/2 = 150, If f = 20, then, p = 2f = 2 • 20 = 40 So, Table as follows:

Number of friends cost of party

50 100

10 20

150 300

20 40
