Answer:
There is no equal sign.
Step-by-step explanation:
There is no equal sign to make it an algebraic equation.
Answer:
Step-by-step explanation:
-5y = -x + 15
5y = x - 15
y = 1/5x - 3
perp. -5
y - 5 = -5(x + 2)
y - 5 = -5x - 10
y = -5x - 5
Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.
Answer:
x=3
Step-by-step explanation:
We are taking 2 times the sum ( addition) of 18 and x
2 ( 18+x) = 42
Divide each side by 2
2 /2 ( 18+x) = 42/2
18+x = 21
Subtract 18 from each side
18+x-18 = 21-18
x = 3
