Answer:

-3x-3y=-24

divide the equation by 3

-x-y=-8

multiply -1

x+y=8

second equation

x+y=8

same equation

so answer is

x+y=8

Answer:

The scale factor of the dilation is 3 ⇒ A

Step-by-step explanation:

In the given figure

∵ EFGH is a polygon

∵ E = (-2, 1), H = (-2, -1)

∵ EH is a vertical side

→ By using the 2nd rule above

∴ The length of EH = 1 - (-1) = 1 + 1

∴ The length of EH = 2

∵ E'F'G'H' is its image after dilation by scale factor k

∵ E' = (-2, 5), and H' = (-2, -1)

∵ E'H' is a vertical side

∴ The length of E'H' = 5 - (-1) = 5 + 1

∴ The length of E'H' = 6

→ By using the 1st rule above

∴  [tex]\frac{E'H'}{EH}[/tex] =  [tex]\frac{E'F'}{EF}[/tex] =  [tex]\frac{H'G'}{HG}[/tex] =  [tex]\frac{F'G'}{FG}[/tex] = k

∵  [tex]\frac{E'H'}{EH}[/tex] = k

∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]

∴  [tex]\frac{E'H'}{EH}[/tex] = 3

∴ k = 3

∴ The scale factor of the dilation is 3

Answer:

m<HJF = [tex]56^{o}[/tex]

Step-by-step explanation:

From the given diagram, ΔFHJ is similar to ΔFEG. So that;

m<HJF = m<EGJ

⇒ 10x + 36 = 6x + 44

10x - 6x = -36 + 44

4x = 8

x = [tex]\frac{8}{4}[/tex]

x = 2

Substitute the value of x in the expression for m<HJF to have,

m<HJF = 10x + 36

           = 10(2) + 36

           = 20 + 36

m<HJF = [tex]56^{o}[/tex]

The measure of angle HJF is [tex]56^{o}[/tex].

Step-by-step explanation:

Answer:

18 gallons

Step-by-step explanation:

Step one:

given data

The gas in Dad's car holds 12 gallons

the gas tank in Moms truck holds 50% more than that in Dad's car

Hence 50% of 12 is

=50/100*12

=0.5*12

= 6 gallons

We are told that the gas tank in Moms truck holds 50% more than that in Dad's car

Therefore Mum's car will hold

=12+6

=18 gallons

Answer:

3

Step-by-step explanation:

y-3 = 3x+12

y = 3x +15

so slope = 3 ( number next to the x)

Step-by-step explanation:

Answer:

312°

Step-by-step explanation:

PSQ = 360°- mPAQ

at mPAQ=mSAR

so PSQ =360°-48°=312°

Answer:

Answer:

312°

Step-by-step explanation:

In this it says to find the measure of PSQ

That means the arc starts at P goes through S and ends at Q.

In this case the only section of the circle that is not included is ∠PAQ

∠PAQ is 48° due to reflexive property

Now subtract 48 out of 360

360 - 48 = 312

312° is you answer

Answer:

[tex]b+1\\b+2\\b+(b+1)+(b+2)=24[/tex]

Step-by-step explanation:

If [tex]b[/tex] represents the youngest brother's age, the second oldest brother's age can be written as [tex]b+1[/tex] and the third can be written as [tex]b+2[/tex], since they're all consecutive.

The sum of all their ages is then [tex]b+(b+1)+(b+2)[/tex] which is equal to [tex]24[/tex], as given.

Answer:

x=5

Step-by-step explanation:

So first we want to find x by itself, so we can subtract 4 from both sides:

x=5

That is your simple answer!

Answer:

270 degrees

Step-by-step explanation:

Take note that to convert Pi to Radians you need to use the formula of

180 degrees = Pi radians

Therefore if you have 180 degrees multiplied by 9 Pi over 6 you get the degree measurement of 270

I believe, The answer to your question is:

B. 270°

Hope I helped! Have a fantastic day! Bye, you got this! :)

Answer:

58°

Step-by-step explanation:

A + B + C = 180 °

The smallest value of C is 91.

A + B = 89

A = 2B - 4

2B - 4 + B = 89

3B - 4 = 89

3B = 93

B = 31

A + 31 = 89

A = 58

Answer: 121 2/3 days

Step-by-step explanation:

Number of days in a year = 365 days

Number of friends = 3 friends

The number of days each year that Alisa need to walk the dog will be:

= Number of days in a year / Number of friends.

= 365 / 3

= 121 2/3 days

= 121 days + (2/3 × 24hours)

= 121 days 16 hours

Note that 24 hours = 1 day

Answer:

54

Step-by-step explanation:

x+2x+2x=5x

90/5=18

18*3=54

Answer:

The answer is 54.

Step-by-step explanation:

Ok buddy

‣Remember that a right angle equals 90 degrees.

‣The numbers lie on a right angle.

‣So watchya gonna do is combine the like terms.

[tex]x + 2x + 2x = 5x[/tex]

‣In an equation, that finna look like:

[tex]5x = 90[/tex]

‣Solve that equation

[tex] \frac{5x}{5} = \frac{90}{5} \\ \\ x = 18[/tex]

‣Therefore, the value of x is 18.

‣We trynna find 3x so plug it.

[tex]3x \\ 3(18) \\ 54[/tex]

‣That fr is the answer, 54.
