Answer:x+42+3x = 90
Combine like terms:
3x+x = 4x
42+4x = 90
Subtract 42 to both sides
90-42 = 48
Divide 4 by 48
48/4 = 12
X = 12
100% right
Step-by-step explanation:
Answer:
x = <u>20</u> units
Step-by-step explanation:
∆KJL is a 30° - 60° - 90° triangle which means that side opposite of 30° is x, side opposite of 60° is x√3, and side opposite of 90° is 2x.
Since side opposite of 90° is 40√2 which is 2x and x is the side opposite of 30° (JL).
2x = 40√2 → 2x ÷ 2 = 40√2 ÷ 2 → x = 20√2.
∆JML is a 45° - 45° - 90° triangle which means that sides opposite of 45° are x and 90° is x√2.
Since side JL is also the side opposite of 90° and the sides opposite of 45° are the value x,
20√2 = x√2 → 20√2 ÷ √2 = x√2 ÷ √2 → 20 = x →
x = 20.
Answer:
$80 dollars.
Step-by-step explanation:
So you get charged $40 to get in and $20 extra for any treatment.
You get 2 treatments so that is $40.
$40+$40=$80 is your answer.
Answer:
y = 7x - 33
Step-by-step explanation:
Using a given point and slope, we need to use point-slope form.
m= 7 (slope)
= 3 (x value from given point)
= -12 (y value from given point)
Now we Substitute values in
Double negative with - (-12) makes 12 positive
Use distributive property for 7(x -3)
Subtract 12 from both sides
Hey there! :)
Answer:
(-1, -3)
Step-by-step explanation:
Use the midpoint formula to derive the coordinates of the midpoint:
Plug in the coordinates given:
Simplify:
(-1, -3) are the coordinates of the midpoint.
