Find the value of each variable. Write an equation then solve showing ALL the work A2x+10°

Answer:

x = 25

Step-by-step explanation:

The three straight lines in the sides of the triangle means that ALL 3 SIDES ARE EQUAL.

This is an equilateral triangle. So all 3 angles are equal.

We know sum of 3 angles in a triangle is 180. Since 3 of the angles are equal, each angle is:

180/3 = 60

The top angle is given as "2x + 10", thus we can say "2x + 10" is equal to 60 degrees. Now we equate and solve for x:

2x+10=60\\2x=60-10\\2x=50\\x=\frac{50}{2}\\x=25

The value of x is 25

What is the inverse of the function f(x) = 3x – 2?<br> f-1(x) =
Eddi Din [679]

Answer:

\frac{x + 2}{3}

Step-by-step explanation:

Replace y with f(x).

y = 3x - 2

Swap x and y and solve for y

x = 3y - 2

x + 2 = 3y

\frac{x + 2}{3}  = y

A washer and dryer cost $869 combined. The washer cost $81 less than the dryer. What is the cost of the dryer?
marysya [2.9K]
W+d=869
w=d-81
plug in
(d-81)+d=869
2d-81=869
+81 both sides
2d=950
÷2 both sides
d=475
dryer cost $475

let's check w=475-81
w=394
475+394=869
869=869
the solution is true :)

SOLVE FOR M. please :)
STatiana [176]

Answer:

m =  - 28

Step-by-step explanation:

\frac{ - 3}{7} m = 12

\frac{ - 7}{3} ( \frac{ - 3}{7})m =  \frac{ - 7}{3}  \times 12

\frac{ - 1}{3} ( - 3)m =  \frac{ - 7}{3}  \times 12

- 1( - 1)m =  \frac{ - 7}{3}  \times 12

1 \times m =  \frac{ - 7}{3}  \times 12

m =  \frac{ - 7}{3}  \times 12

m =  \frac{ - 7}{3}  \times 12

m =  \frac{ - 7}{3} (3 \times 4)

m =  - 28
