51:75
This is the same as 51/75.
Simplify by dividing 3 to the numerator and denominator:
17/25
Divide this to get a decimal:
17 / 25 = 0.68
Now multiply by 100 to get a percent:
0.68 * 100 = 68%
Answer: A
Y-3 = 2(2-3) y=1
y−3=2(2−3)
Step 1: Simplify both sides of the equation.
y−3=2(2−3)
y+−3=−2
y−3=−2
Step 2: Add 3 to both sides.
y−3+3=−2+3
y=1
Step-by-step explanation: y + 5 = 2(2 + 1) y+5=2(2+1)
y=1

Answer:
x = ± 2
Step-by-step explanation:
Given
f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5
Equating the two gives
x² + 1 = 5 ( subtract 1 from both sides )
x² = 4 ( take the square root of both sides )
x = ± 
= ± 2
Thus (- 2, 5) and (2, 5) are solutions
