Alright here's the breakdown
take ($8) and (40hr.) and multiply them (8 x 40)
which should equal
$320
but that's not enough
so
we need to add some hours
so
take the numbers like this ($380-$320)
which should equal
$60
now
take ($60) and divide it by the overtime pay ($12 per hr.)
which equals
the number of overtime hours needed to achieve her goal
which is
(5 hr.)
which is your answer
hope this helps!
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
Answer:
I have solved them but I don't know what to o next
Step-by-step explanation:
1) lx- 11+ 1< 15
+11 on both sides
lx+ 1< 26
-1 on both sides
lx< 25
2) lx-11+1>15
+11 on both sides
lx+1>26
-1 on both sides
lx> 25
Step-by-step explanation:
You know that all the degrees in a hexagon is 720.
84+87+128+150+103=552
Subtract 552 from 720.
You don't want x so just do 720-552=x
Answer:
4000
Step-by-step explanation:
1 ton = 2000 pounds
2 tons = ? pounds
Multiply:
2000 × 2 = 4000
There will be 4000 pounds of crushed stone.
Hope this helped.
