Solve for r by simplifying both sides of the equation, then isolating the variable.
r = 26/3
<span>So we want to know why is it necessary to rename 4 1/4 if we subtract 3/4 from it. First, lets turn 4 1/4 into a fraction: 4 1/4 = 17/4. Now lets subtract 3/4 from it: 17/4 - 3/4 = 14/4. So 14/4 becomes 3 2/4. And now we see why is it necessary to rename 4 1/4. </span>
Answer:
<u>The quotient is four tenths.</u>
Step-by-step explanation:
Let's divide 36 hundredths into 9 tenths:
0.36/0.9 = 0.4
<u>The quotient is four tenths.</u>
Answer:
a). x + y + 90° = 180°
b). x = 67°
y = 23°
Step-by-step explanation:
The sum of all angles in a triangle is 180°.
One of the angles in the figure is a right angle, or 90°. Therefore the sum of the three angles in the figure is:
x + y + 90 = 180
We are also told that x + 2 = 3y.
Rearranging that to isolate x gives us:
x = 3y - 2
Thake the first equation and substitute the above expression of in place of x:
x + y + 90° = 180°
(3y-2) + y + 90° = 180°
4y + 88° = 180°
4 y = 92°
y = 23°
To find angle x, use y = 23°
x = 3y - 2
x = 3*(23°) - 2
x = 67°
The sum 90° + 67° + 23° = 180°

since he works 40 hours per week and gets $16 an hour, that would be 16 * 40 which is 640, so that means he needs a commission rate of 10% as 10% of 6400 is 640.
hope this is helpful!
