34,000
Step-by-step explanation:
100,000-2% equals 2000 that’s the growth Population times that by 17 Years gives you total population growth
Answer:
A car is more fuel efficient and it goes 30 miles per gallon (5/12 gallon to travel 12 1/2 miles)
Step-by-step explanation:
A car : 5/12 gallon to travel 12 1/2 miles
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
B car : 5/7 gallon to travel 20 5/7 miles
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is A car....it gets 30 miles per gallon
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
Answer:
C
Step-by-step explanation: Since x is by itself in the first equation, we can substitute 12x + y = 5 into 12(6-y) + y = 5.
