Answer:
Roger works 30 hours and his brother works 50 hours
Step-by-step explanation:
Let
x ---->the number of hours Roger works in a month
y ---->the number of hours his brother works in a month
step 1
Find out how much they earn per hour
5,400-3,240=$2,160 -----> amount earned by 20 hours of work
$2,160/20=$108 per hour
step 2
Find out how many hours each brother works in a month
Roger
108*x=3,240
x=3,240/108=30 hours
His brother
y=x+20
y=30+20=50 hours

Answer:
It would have $560 after ten years.
Step-by-step explanation:
1) find 6% or .06 of 350
350 x .06 = 21
2) multiply that by the ten years to get how much it will be after that time
21 x 10 = 210
3) add your interest over the 10 years to your original amount
210 + 350 = 560
X: 1, 2, 3, 4, 5
y: 0, 1, 0, 2, 0
function: (1,0) (2,1) (3,0) (4,2) (5,0)
function is identified as a special kind of relation wherein the x-coordinate will only have one corresponding y-coordinate.
inverse of the relation is the interchange of the x and y coordinates.
inverse: (0,1) (1,2) (0,3) (2,4) (0,5)
The inverse is not a function. There are more than one x-coordinate that results to different y-coordinates. This is made evident when x = 0 ; y = 1,3, and 5.
Well, alternate exterior angles are congruent. They will have the same measure. They are equal to each other.
6x+5= 7x-4
Add 4 to both sides.
6x+9= 7x
Subtract 6x on both sides.
9=x
Now, plug in 9 for the measures of the angles.
6(9)+5
54+5= 59
7(9)-4
63-4= 59
The angles equal 59 degrees.
I hope this helps!
