solve 5x + 20=75
What is x

Answer:

332

Step-by-step explanation:

Since there is a ratio of 9:8 (women to men), the total should be 17. So even if there were 81 women and 72 men, the total ratio should still be 17. (In simplifiest form.)

So, 5,644 divided by 17=332

Since 9 is 1 more than 8, there are 332 more women than men.

Hope this made sense! I wasn't sure how to explain this.

Step-by-step explanation:

Just by looking at this question, I say there is no solution because these two equations do not touch or meet on the xy-plane.

- х= -у.........A

6x - бу = 12.........B

Solve A for x.

-x = - y

Divide both sides by negative 1.

Doing so, we get x = y. Plug this into B.

6x - 6y = 12

6(y) - 6y = 12

The left side becomes zero.

0 = 12 is a false statement.

Answer: There is no solution to this system of

equations in two variables.

Answer:

She will run 202 miles in 12 wks.

Step-by-step explanation:

y = 17x + 15

15 represents the # of miles she ran in the first week.

17 represents the amount of miles she will run each week

x represents the # of weeks

y = the total # of miles in 12 weeks.

To solve plug in 11 for x since she ran 15 miles the first week she has 11 more to go.

y = 17(11) + 15

y = 187 + 15

y = 202

Hope this helps!

202 miles Abby will run during her twelfth week of training.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the number of weeks she walk x.

As she ran15 miles in the first week.

and, she run 17 miles in each week.

let y be the total of miles in 12 weeks.

Then, the equation can be

y = 17x + 15

y = 17(11) + 15

y = 187 + 15

y = 202

Hence, 202 miles Abby will run during her twelfth week of training.

a. RG=36 since RG=2(RT)

b.

4x+12=10x-15 Since RG and HI are equivalent

12=6x-15 Subtract 4x from both sides

27=6x Add 15 to both sides

4.5=x Divide by 6 on both sides

to double check:

4(4.5)+12=30

10(4.5)-15= 30

Answer:

72

Step-by-step explanation:

i just know it

If the selling price of an item is ​$480. It is marked down by 10​%, but this sale price is still marked up from the cost of ​$360.Then 72 is the markup from cost to sale price

percentage, a relative value indicating hundredth parts of any quantity.

Given,

The selling price of an item is ​$480

It is marked down by 10​%, but this sale price is still marked up from the cost of ​$360

We need to find 10% of 480

10/100=0.1

0.1×480=48

48 is the 10% of 480

Now subtract 48 from 480

480-48

432

Now subtract 360 from 432

432-360

72

Hence 72 is markup from cost to sale price

Explanation:

Variables can be negative.

Answer:

The percentage for both the cases would be 100% and 35% respectively

Step-by-step explanation:

The computation of the percentage of down payment to the purchase price would be:

In the first case, the percentage would be

= Down payment ÷ Total amount

= $12,000 ÷ $120,000

= 100%

For the second case, the percentage would be

=  Down payment ÷ Total amount

= $42,000 ÷ $120,000

= 35%

The percentage for both the cases would be 100% and 35% respectively

Answer:

m∠R = 69

Step-by-step explanation:

m∠R + m∠S + m∠T = 180       {Angle sum property of triangle}

5x - 11 + 3x - 3 +  3x + 18 = 180

5x + 3x + 3x - 11 - 3 + 18 = 180     {Combine like terms}

                     11x  +4      = 180

                                 11x = 180 - 4

                                 11x = 176

                                    x = 176/11

x = 16

m∠R = 5x - 11

        = 5*16 - 11

        = 80 - 11

m∠R = 69

Answer:

65

Step-by-step explanation:

So let's first set up our equation here:

35 + 42 = 12 + x

Now, let's add like terms

77 = 12 + x

Now, let's subtract both sides by 12

65 = x

Answer:

x=63

Step-by-step explanation:

35+42= 75

75-12= 63

Step-by-step explanation:

Given that,

DE = 8x - 13

EF = 5x + 17

DF = x + 21

Also,

DE = EF

which means that,

8x - 13 = 5x + 17

8x - 5x = 17 + 13

3x = 30

x = 30/3

x = 10

Now,

DE = 8x - 13 = 8×10 - 13 = 80 - 13 = 67cm

EF = 5x + 17 = 5×10 + 17 = 50 + 17 = 67cm

DF = x + 21 = 10 + 21 = 31cm

Answer:

4). y= 2x - 6

5). y= -1x + 3

6). y= -1/3x - 1

Answer:

y=2/3x-16/3    

Step-by-step explanation:

ok ill show you how to do one question since the rest will take too long so what you do is

equation is y=mx+b right

so you have slope and these points (2,-4) and m=2/3

y=2/3x +b right

now all you do is sub in x and y which are ur given points

-4=2/3 (2) +b

now you solve for b

-4 = 4/3 + b

-4-4/3 = b

-12/3 - 4/3 = b

-16/3=b so therefore

y=2/3x-16/3
