Let, the numbers = x,y
Now, x + y = 38
x - y = 50, x = 50 + y
Substitute it into first equation,
50 + y + y = 38
2y = 38 - 50
y = -12 / 2
y = -6
Substitute it into first equation,
x - 6 = 38
x = 38 + 6 = 44
So, your final answer is x = 44 & y = -6
Hope this helps!
Answer:
8
Step-by-step explanation:
The new value would be $134.40; 1.12 times 120
Answer: 4150
Step-by-step explanation:
You take the 50, becuse the amount earned increases once you surpass 40 you do 40 x 10 and that = 4000 then you take the remaining 10 and times that by 15 (becuse after 40 it is 1.5 of what you where earning before you hit 40 hours and half of ten is 5 so you do 10 plus 5 and times that by 10) then add both numbers together and you have 4150! Hope that helped!
Step-by-step explanation:
- a . write the formula for finding area that is area= L by W so to get w will area over length so 4731/83= 57
- perimeter=2( L+ W ) so substitute so that it looks like this 318= 2(L + 72 ) then open the bracket 318= (2L + 144) then move 144 to the other side so 318 - 144 = 2L then you get 174= 2L divide both sides by 2 and your length is 87
