1/8 is rational because irrational numbers can be written as decimals but not fractions
Answer:
27 hours
Step-by-step explanation:
The regular hours are paid normally, 21/hr hence working for 40 hours, Michael earns 40*21=$840
To work x hours paid overtime as 1.5 of the normal rate, the rate would be $21*1.5=$31.5/hr
X hours multiplied by rate of $31.5/hr should be at least equal to $840
31.5x>=840
X>=840/31.5>=26.6667 hours and when rounded off
X is 27 hours
Answer:
-8(-7r-7)+8=-272
We move all terms to the left:
-8(-7r-7)+8-(-272)=0
We add all the numbers together, and all the variables
-8(-7r-7)+280=0
We multiply parentheses
56r+56+280=0
We add all the numbers together, and all the variables
56r+336=0
We move all terms containing r to the left, all other terms to the right
56r=-336
r=-336/56
r=-6
X+10 = # of marbles bob has
x = # of marbles larry has
Set up an equation:
2x+10=29
2x=19
x=9.5
Larry has 9.5 marbles
