Answer:
1: -3
2: She gives him $3 per week
3: 18
4: How much money she initially borrowed
5: y = -3x + 18
A = L * H
A = 65
L = 2H - 3
65 = H(2H - 3)
65 = 2H^2 - 3H
-2H^2 + 3H + 65 = 0
(-Hh + 13)(H + 5) = 0
-2H + 13 = 0
-2H = -13
H = -13/-2
H = 6.5 <== height is 6.5 inches
H + 5 = 0
H = -5....this wont work because it is negative
L = 2H - 3
L = 2(6.5) - 3
L = 13 - 3
L = 10 <== length is 10 inches
Step-by-step explanation:
0.00047. = 47÷10 000
=4.7×10/10^-5
= 4.7×10^-4
Step-by-step explanation:
1/3x=1/6
x/3=1/6
cross multiply
6x=3
divide both sides by 6
x=3/6
x=1/2
