Answer:

5

Step-by-step explanation:

It's a right triangle so 7x + 11x = 90

Solve for x

7x + 11x = 90

18x = 90

  x = 5

11x+7x+90=180
Minus 90 on both sides

18x=90
Divided 18 on both sides
X=5

Kelly has 4 times as many songs on her music player as Lou. Tiffany has 6 times as many songs on her
Novosadov [1.4K]

Answer:

113

Step-by-step explanation:

we need to know how much Lou has first !

so we have to do 682 / 6 which = 113

then 113 / 4 = 28.2

28.2 is how much Lou has

so we will go back and multiply the 4

28.2 x 4 =113

1/4x+3/4y=1 please solve (linear equation)
stealth61 [152]
Convert this to slope-intercept form

subtract 1/4x, 

3/4y=1-1/4x

then multiply my 4/3

y=4/3-1/3x

y=-1/3x+4/3

4/3 is the y-intercept, so when you're graphing begin with it. Then find another point on the graph according to the slope. Plot point (0,4/3) then plot a point with a y-value 1 less and an x-value 3 more. (slope is sometimes called rise over run because it is a ratio of the change in the y-value divided by the change in the x-value) Plot point (3,1/3). Connect the dots with a ruler and draw a line.

How do you solve this
blsea [12.9K]

Answer:

x = 8

Step-by-step explanation:

The angles shown are vertical angles

Vertical angles are congruent hence 8x + 36 = 5x + 60

( Notice that we just created an equation that we can use to solve for x )

We now solve for x algebraically

8x + 36 = 5x + 60

Step 1: Subtract 5x from both sides

8x - 5x + 36 = 5x - 5x + 60

Outcome: 3x + 36 = 60

Step 2: Subtract 36 from both sides

3x + 36 - 36 = 60 - 36

Outcome: 3x = 24

Step 3: Divide both sides by 3

3x/3 = 24/3

Outcome: x = 8
