The path of the car and the limo are straight lines.
To determine the equation of the lines of the paths, the slopes must be determined.
Let m1 = slope of car
m2 = slope of limo
so,
m1 = (7 + 7)/(5 + 2) = 2
m2 = (-5 -9)/(3+4) = -2
therefore the equations are
car:
2x – y = 2(5) –(7)
2x – y = 3
Limo:
2x + y = 2(3) – 5
2x + y = 1
Solving the intersection of the equations (using a calculator)
x = 1
y = -1
(820*7)-(480*7)=? This is how to solve the equation
Answer:
28pounds
Step-by-step explanation:
0.45=1pound
12.6
12.6/0.45=28pounds
1 gallon = 16 cups
1 quart = 4 cups
1 pint = 2 cups
Therefore...
Multiply
5 gallons × 16 cups = 80 cups
12 quarts × 4 cups = 48 cups
7 pints × 2 cups = 14 cups
Then...
Addition
80 cups + 48 cups + 14 cups = 142 cups
Answer
Myong has 142 cups of rainwater after 3 weeks of collecting rainwater.
Answer:
Perimeter of the smaller square = 9 ft
Perimeter of the larger square = 18 ft
Step-by-step explanation:
Let
Perimeter of the smaller square = x
The perimeter of the larger square is twice the perimeter of the smaller square.
Perimeter of the larger square = 2x
Total Length of the piece of wire = 27 ft
Total = smaller + larger
27 = x + 2x
27 = 3x
x = 27/3
x = 9 ft
Perimeter of the smaller square = x
= 9 ft
Perimeter of the larger square = 2x
= 2(9)
= 18 ft
