thec correct equation of the line is : y = 3 + 1.5x

tep-by-step explanation:

Answer:

3/4 25% 2.8x10

Step-by-step explanation:

Answer:

Step-by-step explanation:

3x - 4 = x + 4

2x - 4 = 4

2x = 8

x = 4

BC = 4 + 4 = 8

Answer:

20cm squared

Step-by-step explanation:

so the scale factor is 1:2 so you just double the area so,

10cm squared x 2 = 20cm squared

Answer:

D: 40

Step-by-step explanation:

If the scale factor is 1:2 it means that each side is twice as big after being scaled. However, because the area is width * height that means that the area of the scaled one gets doubled two times, so is actually 4x bigger. This means the answer is 4 * 10 = 40 square cm

Hey there!

For equations like this I usually find the GCF or Factors of the given numbers for both of numbers and factor/solve it from there!

So, I’ll do the same thing for you.

[tex]\bf{4x: 1,2,4,\& \ x}\\ \bf{16: 1,2,4,8}}[/tex]

GCF: [tex]\bf{4}[/tex]

[tex]\boxed{\bf{Answer: 4(x - 4)}}\checkmark[/tex] (Just distribute and it’ll convert back to the equation in your question

Good luck on your assignment and enjoy your da!

Answer: 11,600

you multiply 58,000 by 0.8 and you’d get 46,400. then you would subtract that number by 58,000 to get the answer of 11,600.

Answer:

length=48cm

Step-by-step explanation:

a²+14²=50²

a²+196=2500

a²=2304

a=48

Answer:

Step-by-step explanation:

it means the ABC And DEF have side lengths of 15,19, 25

so 3x-3 = 15

x = 6

5-y = 19

so y = -14

Answer: both services will cost the same if it is for 3 hours service.

Step-by-step explanation: Hope this helps.

Define x: Let x be the number of hours

Derrick Dogs sitting:

Fixed charged=$12

Hourly change=$5

Total charge=12+5x

Darlene dog sitting:

Fixed charged=$18

Hourly change=$3

Total charge= 18+3x

Find the total number of hours so that both cost are the same:

12 + 5x = 18 + 3x

5x - 3x = 18 - 12

2x = 6

x = 3

ANSWER: both services will cost the same if it is for 3 hours service

Answer:

3 hours hon

ITS B I GOT IT RIGHT ON THE EXAM

Answer:

b Yes, because the number of wheels is specific to the number of cars in the parking lot

Step-by-step explanation:

because i did this quiz and got it right

Answer:

this is not originally by me

Step-by-step explanation:

10t = b - 4

12b+8t = $348

This is a system of equations. I’ll be solving through substitution.

In the first equation. solving for b (the easier variable to isolate) gives you:

b = 10t + 4

Substitute this into the second equation:

12(10t+4) +8t = 348

120t+48+8t = 348

128t = 300

t = 2.34375 —> round it to the nearest cent to get 2.34 dollars

b = 10t+4

b = 10(2.34)+4

b = 27.4 dollars

Answer:

[tex]Total = 20v + 40x + 80y[/tex]

[tex]Total = 20(v + 2x + 4y)[/tex]

Step-by-step explanation:

The options were not given,en but the question can still be solved.

Given

[tex]Daises = \$ x[/tex]

[tex]Magnolias = \$ y[/tex]

[tex]Vase = \$ v[/tex]

Required

Determine the cost of 20 vases, 40 daises and 80 magnolias

If 1 vase costs $v, then

[tex]20\ vases = 20 * v[/tex]

[tex]20\ vases = 20v[/tex]

If 1 daises costs $x, then

[tex]40\ daises = 40 * x[/tex]

[tex]40\ daises = 40x[/tex]

If 1 magnolias costs $y, then

[tex]80\ magnolias = 80 * y[/tex]

[tex]80\ magnolias = 80y[/tex]

[tex]Total = 20v + 40x + 80y[/tex]

Another expression that represents the total is to factorize the expression.

[tex]Total = 20(v + 2x + 4y)[/tex]

Step-by-step explanation:

Answer:

Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.

Width = A

Length = B

Diagonal = C

so: a2+b2=c

2502+1002=c2

2500+10000=c2

12500=c2

c=√12500

c=111.80 yards

Step-by-step explanation:

Answer:

more than 20%

Step-by-step explanation:

3.00/12.50 = .24

Meaning the tip was 24% ( more than 20% )

Answer: 9/8

Step-by-step explanation:

The square root of this is 9/8 because when you square 9/8, you get 81/64, and when you square root it, you get 9/8.

The easiest way tho is knowing that when you square a number and square root the square, you get the same number, cuz the square root cancels the square. Does that make sense?

Anyways hope this helped!

Answer:

6/42 = 1/7

Step-by-step explanation:

1/6 x 42/1

1 x 42 = 42

6 x 1 = 6

simplify to 1/7 (6 divided by 6 = 1, 42 divided by 6= 7)

hope this helps :)
