Answer:
Julia has enough gas to mow the two yards.
Step-by-step explanation:
Given:
Julia needs gallon of gas to mow first yard.
Julia needs gallon of gas to mow second yard.
Julia has a total of gallon of gas in in her can.
To find whether she has enough to mow both yards.
Solution:
Total gallons of gas needed to mow two yards can be found out by :
⇒
Taking LCD =80.
⇒
⇒
Adding the numerators.
⇒
⇒ 1.2125 gallons
Julia has gallon = 1.5 gallons of gas in in her can.
Since , thus we can say that Julia has enough gas to mow the two yards.
The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.
2/5 = 18/45
4/9 = 20/45
Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
Answer:
,
Step-by-step explanation:
<h3>
I will use the elimination method.</h3>
We want to make the X's the same:
Because the signs of the X's are the same we subtract the 2 equations to make:
(I put the second one on top of the 1st)
So:
Substitute y into either equation 1 or 2:
(I chose equation 1)
So:
1 + 54 = 55
2 + 53 = 55
3 + 52 = 55
4 + 51 = 55
5 + 50 = 55
6 + 49 = 55
7 + 48 = 55
8 + 47 = 55
9 + 46 = 55
10 + 45 = 55
and so on...
I hope that helps. :)
The finance Charge would be $140. you would multiply 18 by 80 and then add the 130 and take that number and subtract the 1,430
