Answer:
C
Step-by-step explanation:
97.62+22.95+14.78=135.35
135.35*.07
9.4745
Rounded to 9.47
So 8.34=3/4 of preset
find 4/4 of present
divide 8.34 by 3
8.34/3=2.78=1/4 of present
1/4 times 4=4/4
2.78 times 4=4/4 present=11.12
answe ris present cost $11.12
To solve this problem you must apply the proccedure shown below:
1. You have that :
-The <span>estimate from the moving is $675 for 6 hours of packing and 5 hours of moving.
- </span>The cost will decrease to $425 for 4 hours of packing and 3 hours of moving.<span>
x: rate for packing.
y: rate for moving.
6x+5y=675
4x+3y=425
2. When you solve the system of equations shown above, you obtain:
x=50
y=75
Therefore, the answer is: $50 (Rate for packing) and $75 (Rate for moving).

Answer:
A.(-2, 0)
C. (-1.4)
Step-by-step explanation:
we know that
If a point lie on the line, then the point must satisfy the equation of the line (makes the equation true)
we have
subtract 7 both sides
divide by 2 both sides
Substitute the value of x and the value of y of each point in the linear equation and analyze the result
<u><em>Verify each point</em></u>
case A) we have
(-2, 0)
For x=-2, y=0
substitute
---> is true
so
the point lie on the line
case B) we have
(1, 3)
For x=1, y=3
substitute
---> is not true
so
the point not lie on the line
case C) we have
(-1, 4)
For x=-1, y=4
substitute
---> is true
so
the point lie on the line
case D) we have
(1, -4)
For x=1, y=-4
substitute
---> is not true
so
the point not lie on the line
case E) we have
(0, -1)
For x=0, y=-1
substitute
---> is not true
so
the point not lie on the line
The dash on each side of the triangle show that those three sides have the same measurement. Therefore, divide 24 by 3 to get 8, which is the measurement for each side of the triangle.
Meaning your answer is:
a. 8cm, 8cm, 8cm
