Answer:

x = 3.75 or [tex]3\frac{3}{4}[/tex]

Step-by-step explanation:

17 = -13 - 8x

add 13 to both sides

17 + 13 = -13 + 13 + 8x

30 = 8x

divide both sides by 8

30/8 = 8x /8

3.75 = x

Step-by-step explanation:

angles FGH and FHG

Step-by-step explanation:

Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is  angles FGH and FHG

Answer:

x=9

Step-by-step explanation:

First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.

You then come up with 13.5=1.5x

Divide both of them by 1.5 and then you get x=9

Answer:

X=9

Step-by-step explanation:

Okay first Hello! :)

so, B is the mid point of the segment midpoint means the half way

so, if AB= 5x+18 is the half to get the whole you would need to times it by 2

you get 10x+36

so now you equal them together

10x+36= 13x +9

Always move your smaller x, and now you got

3x+9=36

move your 9 over and switch the sign you get

3x=27

divide by three and you get

X=9

Answer:

  -2 ≤ x < 12

Step-by-step explanation:

-15x +4 ≤ 34

Add 15x-34 to both sides

  -30 ≤ 15x

Divide by 15

  -2 ≤ x

__

-6x +70 > -2

Add 6x +2 to both sides

  72 > 6x

Divide by 6

  12 > x

The two solution spaces overlap. Since the AND of the two inequalities is involved, the solution of both is just that part of the number line where there is overlap.

The solution is ...

Answer: 1/2 of 12 = 1/4 of 24 and 1/3 of 90 = 2/3 of 45

Step-by-step explanation:

Answer:

1. 1/4 of 24

half of 12 is 6.

6+6+6+6 = 24

1/4 of 24 is 6

1/2 of 12 is 6

2. 2/3 of 45

1/3 of 90 is 30

15+15+15 = 45

so 2/3 would be 30

Answer:

11

Step-by-step explanation:

the square root of 129-8 will equal to 11

Answer:

y = 11

Step-by-step explanation:

You first have to insert the x value.

y equals the square root of 129 minus 8

Which would leave it to be the square root of 121 which is 11.

Answer:

h = 59 hours

Step-by-step explanation:

Total earnings = fixed charge + variable charge

Fixed charge = $65

Variable charge = $15h

Where, h = number of hours

Total earnings = $950

Total earnings = fixed charge + variable charge

950 = 65 + 15h

Subtract 65 from both sides

950 - 65 = 65 + 15h - 65

885 = 15h

Divide both sides by 15

h = 885 / 15

= 59

h = 59 hours

Part (i)

Answer:  m/n

--------------------

Explanation:

You divide the total bill over the number of people at the dinner. This leads to the quotient and the amount each person pays (each person pays the same amount).

====================================================

Part (ii)

Answer:  80 dollars

--------------------

Explanation:

Plug in m = 400 and n = 5 to get

m/n = 400/5 = 80

====================================================

Part (iii)

Answer:  m = 7x

--------------------

Explanation:

x = m/n

x = m/7

7x = m ... multiply both sides by 7

m = 7x

The total bill is 7 times of what each person paid.

====================================================

Part (iv)

Answer:  7 people

--------------------

Explanation:

x = 20 is the amount each person paid

m = 140 is the total bill

n = number of people who went to dinner

x = m/n

20 = 140/n

20n = 140 ..... multiply both sides by n

n = 140/20 ..... divide both sides by 20

n = 7

Seven friends went to do dinner, splitting a $140 bill, paying $20 each

Answer:

m/n; $80; 7*x; 7 friends

Step-by-step explanation:

(I) $x=$m/n

(II) $x=400/5=$80

(III) $m=7*x

(IV) n=140/20=7
