63/3= 21
So 21 miles per gallon of gas
To find 7, you multiply it by 7
21*7= 147
147 miles on 7 gallons of gas
Answer:
54.2
Step-by-step explanation:
add them all up then divide by the total amount of number there are
A) The variable on the horizontal axis of the graph (the independent variable) is "pounds of rice". That is what the first number in the ordered pair (6, 18) represents.
The variable on the vertical axis of the graph (the dependent variable) is "total cost in dollars". That is what the second number in the ordered pair represents.
(6, 18) represents that the total cost of purchasing 6 lbs of rice is $18.
B) The unit price is found at the point where the independent variable has the value 1. That would be at the point (1, 3), which indicates the unit price is $3 per pound.
C) You would have to buy 4 lbs of rice for the total cost to be $12. There are at least two ways to find the answer.
- Draw a horizontal line on the graph at cost = $12. It intersects the graph at lbs = 4.
- Divide the total cost by the unit price. $12/($3/lb) = 4 lb.
Answer:
Step-by-step explanation:
Youre given the adjacent and hypotenuse, so you can use cosine. SOHCAHTOA
cos(37) = 48/x
x = 60.1
((x+2)(x+2))-((x-5)(1))=A
x^2+4x+4-x+5=A
x^2+3x+9=A
