Answer:

x=15 degrees

Step-by-step explanation:

The given triangle is isosceles, so both base angles are both (3x+18).

We also know that angles on a line add up to 180 degrees, so

(3x+18) + (8x-3) = 180 degrees

Simplify

11x + 15 = 180 degrees

11x = 180-15 = 165

Divide by coefficient on left-hand side

x = 165/11 = 15 degrees.

Julio ​says, "If you subtract 13 from my number and multiply the difference by -3​, the result is -54 ​." What is Julios​'s ​num
Alchen [17]

Answer:Julios​'s ​number is 31

suppose: Julios​'s ​number is x

because Julio ​says, "If you subtract 13 from my number and multiply the difference by -3​, the result is -54 ​"

=> we have: (x - 13).(-3) = -54

                 <=>  x  - 13 = (-54):(-3) = 18

                   <=> x = 18 + 13 = 31

                   <=> x = 31
