solve 4x-3 = 2x+7.​

Answers

Answer:

x=5

Step-by-step explanation:

4x-3 = 2x+7.​

Subtract 2x from each side

4x-2x-3 = 2x-2x+7.​

2x-3 = 7

Add 3 to each side

2x-3+3 = 7+3

2x= 10

Divide by 2

2x/2 = 10/2

x = 5

Answer:

x=5

Step-by-step explanation:

4x -3 = 2x +7

Let's start by getting the 2x away from the seven. Subtract the 2x from itself and from 4x. We will subtract 2 because a negative will cancel out the positive.

2x -3 = +7

Now let's get the -3 away from 2x. Add 3 to the -3 and the +7. We will add because a positive will cancel out the negative.

2x = +10

Then divide +10 by 2 to get the final answer.

What is HCF of 5a and 15a
Please help me I don’t understand

Answers

Answer:

5a.

Step-by-step explanation:

The HCF is short for Highest Common Factor.

Write the 2 expressions in factor form:

5a = 5 * a

15a = 5 * 3 + a

Note that 5 and a are common to both sets of factors, so the HCF = 5a.

The pizza shop is running a special: 2 medium pizzas
for $6.99 each. How much would it cost to by 12
pizzas?​

Answers

Answer:

41.94

Step-by-step explanation:

12 divided by 2 is 6 and six times 6.99 gets you your answer of 41.94

Answer:

$72.00

Step-by-step explanation:

Lets round $6.99 to $7.00. Now we have an easier number to work with.

To find the total price of 12 , we need to multiply $7.00 by 12.

⇒ $7.00 x 12 = $84.00

Since we added 1 cent to $6.99 and multiplied by 12, we need to sutract 1 times 12.

1 x 12 = 12

$84 - $12 = $72.00

Answers

Answer:

A. x=35

B. C= 59 degrees

Step-by-step explanation:

Since both angles have the same measurement you set them equal to each other as so & solve for x

3x+16=5x-54

16=2x-54

70=2x

x=35

Now we plug 35 into one of the equations

3(35) + 16

105+ 16 = 121 degrees

Since angle C is a supplementary angles you do 180-121= 59 degrees

llene is making bows for gift wrapping. She uses 1 feet of ribbon for each 3 bow. How much ribbon will she need to make 12 bows?​

Answers

Answer:

4 feet

Step-by-step explanation:

Because if she used 1 feet of ribbon for 3 bows you need to multiply by 4 to 1 foot and you will get 12 bows

Answer:

4 feet of ribbon

Step-by-step explanation:

Because she uses 1 feet of ribbon for each 3 bows, we can create a fraction.

1 ft / 3 bows = x ft / 12 bows

Cross multiplying, we get: 3x = 12

Divide by 3 and we get x = 4 (x in this case is in feet)

Diana is comparing the membership costs at two fitness centers. The community fitness center costs $60 per month. The fitness center located where she works has a $100 registration fee and costs $40 per month. After how many months of membership will the costs be the same?

2
3
4
5

Answers

Answer:

5 months

Step-by-step explanation:

Make the question into an equation where the cost of one gym equal to the cost for the other.

60x = 100 + 40x

x represents how many months

20x = 100

x = 5

It would take 5 months of membership for the costs to be the same.

The answer is 5 months.

How to make a linear equation?

The linear equation is made using the constraints given in the question, examining whether the data is added, subtracted, divided, or multiplied.

How to solve a linear equation?

To solve the linear equation we group the variable on the LHS and then equate it with the constant and this is done by transposing, or using an arithmetic operator on both sides.

The solution to the given problem

Let the number of months taken be 'x'

SO the community fitness takes 60x money for x months

The fitness center where she works takes an amount of 100+40x for x months as registration fees are only charged once.

so equating the equation to find the value of x.

100+40x = 60x

Transposing 40x from LHS to RHS

100=60x-40x

20x = 100

Dividing the equation by 20 on both sides

x = 5

The membership costs will equal in 5 months.

Christa has a rectangular rug in her living room that is 6 feet wide and 8 feet long. She decides that the rug is too small for the room, so she orders a new one that covers twice as much area. If the new rug is 1.5 times as wide as the original rug, how long, in feet, is the new rug?

Answers

Given:

A rectangular rug in her living room that is 6 feet wide and 8 feet long.

She orders a new one that covers twice as much area.

New rug is 1.5 times as wide as the original rug.

To find:

The length of new rug.

Solution:

We have,

Length of rug = 8 feet

Width of rug = 6 feet

Area of rug is

[tex]Area=length \times width[/tex]

[tex]A_1=8 \times 6[/tex]

[tex]A_1=48\text{ sq. feet}[/tex]

Area of new rug is twice of area of original rug.

[tex]A_2=2\times A_1[/tex]

[tex]A_2=2\times 48[/tex]

[tex]A_2=96\text{ sq. feet}[/tex]

New rug is 1.5 times as wide as the original rug.

Width of new rug = 1.5 × 6 = 9 feet

Let the length of new rug be x feets. So, area of new rug is

[tex]A_2=x\times 9[/tex]

[tex]96=x\times 9[/tex]

Divide both sides by 9.

[tex]\dfrac{96}{9}=x[/tex]

[tex]\dfrac{32}{3}=x[/tex]

[tex]x=\approx 10.67\text{ feet}[/tex]

Therefore, the length of new rug is about 10.67 feet.

Alina is 6 years older than Greg. Amy’s age is 2.5 times Alina's age. Amy is 40. How old is Greg?

A. 16
B.10
C. 15
D.10

Answers

Answer:

Hi friend! The answer is D. 10

I hope this helps!

Answer:

B) 10

Step-by-step explanation:

Assign variables to each person:

A=Alina's Age

M=Amy's Age

G=Greg's Age

Set up a system of equations given the information:

A=6+G

M=2.5A

M=40

Notice that M is already given, so we can plug that into the second equation:

40=2.5A

16=A

So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:

16=6+G

10=G

So Greg is 10 years old, therefore B is the correct answer.
