Answer:
E
Step-by-step explanation:
11x-4<15
11x<11
x<1
12x-7>-25
12x>-18
x>-3/2
x<1 or x>-3/2, that covers the whole x-axis domain
Forty four divided by three is 14 1/3

Answer: <u> </u><u> </u><u>d</u><u> </u><u>is</u><u> </u><u>2</u><u>0</u><u> </u>
Step-by-step explanation:

k is a constant of proportionality
• When p = 3, d = 5.

• Therefore, equation becomes;

• Let's find d when p is 12;

Answer:
6.1 gallons of 100% antifreeze and 48.9 gallons of 10% antifreeze
Step-by-step explanation:
Let the amount of 100% antifreeze be x gallon
let the amount of 10% antifreeze be y gallon
total amount to drum = 55 gallons
therefore x + y = 55 -------------------------------Eqn 1
100%(x) + 10(y) = 20%(55)
x + 0.1y = 11--------------------------------------Eqn 2
Both equations are solved simultaneously
From eqn 1 x = 55-y
Substitute x = 55-y into eqn 2
55-y+0.1y = 11
collecting like terms
44 = 0.9y
y = 48.88889
x = 55- 48.88889 = 6.11111 gallons
Therefore 6.1 gallons of 100% antifreeze and 48.9 gallons of 10% antifreeze
The halfway point is 24
• First, add the two numbers: 32 + 16 = 48
• Second, divide the total by 2: 48/2 = 24
