Answer:
34.1
Step-by-step explanation:
8 4/5 is not needed. The other two will given you the answer.
Area = 1/2 * b * h
b = 12 2/5 = 12.4
h = 5 1/2 = 5.5
Area = 1/2 * 12.4 * 5.5
Area = 34.1 square feet.
This can be factored into (2t - 9)(t + 7)
Answer:
5700000
Step-by-step explanation:
Answer:
25
Step-by-step explanation:
We need to set up a system of equations, then solve for the number of board markers.
Let r represent red pens, let b represent board markers.
She has 41 items, so our first equation is r+b=41.
The total cost is $46.30, so our second equation is .55r+1.5b=46.3.
r+b=41
.55r+1.5b=46.3
Let's use substitution.
r+b=41
r=41-b
.55r+1.5b=46.3
.55(41-b)+1.5b=46.3
22.55-.55b+1.5b=46.3
22.55+.95b=46.3
.95b=23.75
b=25
He bought 25 board markers.
