Rememer that the perimiter is the distance around
it is
P=L+L+W+W or
P=2L+2W or
P=2(L+W)

so

a.
tenis
L=2x+6
W=x
P=2(2x+6+x)=2(3x+6)=6x+12

basketball
L=3x-14
W=1/2x+32
P=2(3x-14+1/2x+32)=2(3.5x+18)=7x+36



b.
how much bigger is basketball than tennis
7x+36=bigger+6x+12
minus 6x+12 both sides
x+24=bigger
it is x+24 bigger


c.
x=36
Ptenis=6x+12=6(36)+12=216+12=228ft
Pbasketball=7x+36=7(36)+36=252+36=288ft

2x + 7 ≤ 3x - 5

Start by keeping the variable x on the left side of the inequality, and move everything else to the right side.

We can do this by subtracting 3x from both sides and subtracting 7 from both sides.

-x ≤ -12

Divide both sides by -1 to make x a positive; when dividing by a negative number you will flip the inequality sign, so ≤ becomes ≥.

x ≥ 12

Possible solutions for x are any number equal to or greater than 12.

Michael makes 60% of his free-throw attempts. If Michael attempts two free-throws,
nikklg [1K]
<h3>Answer:  12/25</h3>

====================================================

Reason:

60% = 60/100 = 0.6 is the probability of making any given free-throw.

1 - 0.6 = 0.4 is the probability of missing any given free-throw.

We have these probabilities

  • A = P(making 1st, missing 2nd) = 0.6*0.4 = 0.24
  • B = P(missing 1st, making 2nd) = 0.4*0.6 = 0.24

The probability of making exactly one free throw is A+B = 0.24+0.24 = 0.48

Convert this to a fraction:

0.48 = 48/100 = (4*12)/(4*25) = 12/25
