The route will take four hours and fifteen minutes. If you start at 9:50 and count four hours, you'll get to 1:50, add ten to get to 2:00, then add 5 minutes to get to 2:05. Four hours plus ten minutes plus five minutes, 4:15.
Answer:
The cost of 1 ruler and 1 pencil are $0.35 and $0.25 respectively,
Step-by-step explanation:
Let the cost of 1 ruler be x
Let the cost of 1 pencil be y
Cost of 4 rulers = 4x
Cost of 3 rulers = 3x
Cost of 3 pencils = 3y
Cost of 4 pencils = 4y
We are given that Four rulers and three pencils cost £2.15
4x+3y=2.15 ---- Black line
We are also given that Three rulers and four pencils cost £2.05
3x+4y=2.05 --- Red line
Plot the lines on the graph
Point of Intersection of lines is (0.35,0.25)
Cost of a ruler = $0.35
Cost of a pencil = $0.25
Hence The cost of 1 ruler and 1 pencil are $0.35 and $0.25 respectively,
1.19 dollars/quart x 1 quart/ 32 ounces = .037 = 3.7 cents per ounce
when you set up the multiplication, since quarts are in the denominator initially and you want to get rid of them, set the quarts in the numerator of the unit rate (1 quart/ 32 ounces) so that the units cancel and you are left with the units that you wanted ($/ounce).
Clear as mud?! :)
The slope for the line would be a triangle
