Answer:
1
Step-by-step explanation:
5(0)+1=1 because 5x0=0 then add the 1
First, convert the percentage into a decimal by removing the % sign and dividing by 100.
40% => 0.4
The word 'of' in mathematics can mean multiplication.
0.4 * 126 = 50.4
However much the barber charges.
His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
Answer:
Clockwise
Step-by-step explanation:
The angle is measured from the initial side to the terminal side by the amount of rotation. The measurement is positive if measured in a counterclockwise direction. The measurement is negative if measured in a clockwise direction.
