Cross mutiply. 42*10= 420. 14*g= 14g
14g= 420
divide by 14 for both sides
14g/14= 420/14
g= 30
Check answer by using substitution method
42/30. Divide by 3 . 42/3= 14 , 30/3= 10
14/10 and 14/10 equal to each other by dividing 2.
14/2= 7 , 10/2= 5
7/5= 7/5
Answer: g= 30
Answer:
i think 2
Step-by-step explanation:
65km ÷ x = 6 1/2km×5
65÷x = 6 1/2×5
65÷x = 13/2 ×5
65÷x = 65÷2
x = 2
so 2 is answer
Answer:
a. y(cost) = 4.95g + 5.45c
b. $91.12
Step-by-step explanation:
a. Joe bought g gallons of gasoline for 4.95, this can be represented as 4.95g. He bought c cans of oil for 5.45, this can be represented as 5.45c. Add them together to find the total cost, and it will look like this: y(cost) = 4.95g + 5.45c.
b. g = 9.6 gallons
c = 8 cans of oil
Plug these into the equation we did in part A
y(cost) = 4.95(9.6) + 5.45(8)
Solve
y(cost) = 47.52 + 43.6
y(cost) = 91.12
Therefore, if Joe bought 9.6 gallons of gasoline and 8 cans of oil, all in all he spent $91.12.
