Answer:
Car 1 : 40 miles per gallon
Car 2: 25 miles per gallon
Step-by-step explanation:
family has two cars. During one particular week, the first car consumed 15 gallons of gas. The second car consumed 25 gallons of gas. The two cars Drove a combined total of 1475 miles and the sum of their fuel efficiency was 65 miles per gallon. What were the fuel efficiency of each of the cars that week
Given that :
Fuel efficiency , car 1 = x
Fuel efficiency , car 2 = y
x + y = 65 - - (1)
15x + 35y = 1475 - - - (2)
x = 65 - y
15(65-y) + 35y
975 - 15y + 35y = 1475
20y = 14875 - 975
20y = 500
y = 25
Put y = 25 in (1)
x + y = 65
x + 25 = 65
x = 65 - 25
x = 40
Answer:
Combine the ones to make 8 ones
Step-by-step explanation:
It seems the most reasonable. (Also, all the other options are wrong-) I just don't see why it's making you go through this process when you can just add 12 + 6 in your head lol.
Around 81 whole apples
34 divided by 41.5 = 0.81927711
0.81927711 x 100 = 81.9.....
So that rounded 81 whole apples and 0.9.... of an apple
It’s 81 apples
It’s D , -16.2
you replace X with -142 and get -0.2 (142 + 223)
