Answer:
-25
Step-by-step explanation:
if you are multiplying x by -2/5 you have to divide each side by it to get
x = 10 ÷ -2/5
and if you change it to (10/1)/(-2/5)
=(10/1) • -5/2
and whene you multiply them you get -50/2
which is -25/1 or -25

Answer:
The answer of your question is: x = 5
Step-by-step explanation:
It's and isosceles triangle then ∠ A = ∠C
73 = 8y - 7
8y = 73 + 7
8y = 80
y = 80 / 8
y = 10
∠ C = 8(10) -7
∠ C = 73°
The sum of the internal angles in a triangle equals 180°
∠A + ∠B + ∠C = 180°
73° + (6x + 4) + 73° = 180° Substitution
6x + 4 = 180 - 73 - 73
6x =34 - 4
6x = 30
x = 30 / 6
x = 5
Answer:
C
Step-by-step explanation:
i dont really know anything about angles but it looks like the 3x is the exact same angle as 30 degrees on the other side of it
3x=30
x=10
