it means to do the problem in the parenthesis first
Answer:
x = -5
Step-by-step explanation:
If g(x)= 3x - 12, and g(x)= -27 then -27 = 3x -12
Solve for x
-27 = 3x -12, add 12 to both sides
-27+12 = 3x, add -27+12
-15 = 3x, divide both sides by 3
-5 = x
Answer:
Standard Form
Step-by-step explanation:
When m is 0, the other 2 variables is 0 as well.
when m is 1, the other 2 variable is 20.
when m is 2, the other 2 variable is 40.
when m is 3, the other 2 variable is 60
when m is 4, the other 2 variable is 80.
Im not too sure what you write for the second column in the table, but I think you can just write 20 times the number, whatever m is.
2250= plastic beads
6750= metal beads
STEP 1:
Find total number of beads on clearance
= 2250 + 6750
= 9000 total beads on clearance
STEP 2:
set a ratio; number of plastic beads on clearance to the total number of beads on clearance is what number out of 100
x= percent out of 100
2250/9000= x/100
cross multiply
(9000*x)= (2250*100)
9000x= 225,000
divide both sides by 9000
x= 25%
CHECK:
multiply total number of beads by 25%
= 9000 * 25%
= 9000 * 0.25
= 2250 number of plastic beads
ANSWER: 2250 beads is 25% out of the total number of beads on clearance.
Hope this helps! :)
