Answer:
c
Step-by-step explanation:
Let 1/x = a &
1/y = b
So, now the equation:
2a +3b = 13 --------------------(i)
5a - 4b = -2 --------------------(ii)
To eliminate a, Multiply equation (i) by 5 and multiply (ii) by (-2)
(i)*5 10a + 15b = 65
(ii)*(-2) <u> - 10a + 8b = 4</u> ( Now add, a will be eliminated}
23b = 69
b= 69/23
b = 3
Plug in the value of b in equation (i)
2a + 3*3 = 13
2a + 9 = 13
2a = 13 - 9
2a = 4
a= 4/2
a = 2
Now a = 1/x ------>x = 1/a = 1/2
b = 1/y ----------->y = 1/b = 1/3
Answer:
The queen palm tree
Step-by-step explanation:
I think you were saying years not inches but pretty much if you divide 85 divided by 5 you get 17 but if you divided 86 divided by 8 you get 12 so 12 is less than 17.
Answer:
9 gallon of gas
Step-by-step explanation:
When distance covered is 378 miles, they have used 14 gallons of gas
We need to find how much gas will they need to finish the trip if 243 miles left to drive on the trip.
378 miles = 14 gallons of gas
For 1 mile,
1 gallon of gas is used for 
For 243 miles,
Hence, for 243 miles 9 gallon of gas is used.
