Answer:
83%
Step-by-step explanation:
65/78=.83333333333333
0.833333333 turnes into 83% once rounded and multipyled by 100
Answer:
13
Step-by-step explanation:
3b + 8b + 37° = 180° (angle sum property of a triangle)
11b + 37° = 180°
11b = 180° - 37°
11b = 143
b = 143/11
b = 13
hope u understood:))
Answer: A. 8.75
Step-by-step explanation: y=12.5x
Step 1: Flip the equation.
12.5x=y
Step 2: Divide both sides by 12.5.
12.5x/12.5=y/12.5 x=8
The answer was 0.8, but I moved the decimal over and it was 80% I simplified it to 8.75
Answer:
x = -2 ±sqrt(7)
Step-by-step explanation:
3x^2 +12 x = 9
Divide each side by 3
3x^2 /3 +12x/3 = 9/3
x^2 +4x = 3
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add it to each side
x^2 +4x+4 = 3+4
x^2 +4x+4 = 7
(x+2)^2 = 7
Take the square root of each side
x+2 = ±sqrt(7)
Subtract 2 from each side
x+2-2 = -2 ±sqrt(7)
x = -2 ±sqrt(7)
