For the first one his car used 8/340 or 2/85 gallons for one mile.
After the fix, his car 7/350 or 1/50 gallons for one mile.
Then you subtract 1/50-2/85 to get (17-10)/850 or 7/850.
You multiply this by 4 to get 28/850 which is $0.0329411
Since it is asking for cents you multiply by 100 to get approximately 3 cents.

Step-by-step explanation:
3 pieces such that each piece is 2 cm longer then the next...
x , x + 2, x + 4
x + x + 2 + x + 4 = 30
3x + 6 = 30
3x = 30 - 6
3x = 24
x = 24/3
x = 8
x + 2 = 8 + 2 = 10
x + 4 = 8 + 4 = 12
check...
8 + 10 + 12 = 30
18 + 12 = 30
30 = 30 (correct)...it checks out
the ribbon lengths are : 8 cm, 10 cm, and 12 cm

Step-by-step explanation:
This is a four side figure which is most likely to be a trapezium.So AD is the hypotenuse,AB is side (a),BC is the height and CD is side (b).
Answer:
x = ±2
Step-by-step explanation:
A equation is given to us , which is ,
![\longrightarrow 2log_5(x) = log_5 4](https://tex.z-dn.net/?f=%5Clongrightarrow%202log_5%28x%29%20%3D%20log_5%204%20)
From <u>properties </u><u>of </u><u>logarithm </u>we know that ,
![\longrightarrow alog\ m = log \ m^a](https://tex.z-dn.net/?f=%5Clongrightarrow%20alog%5C%20m%20%3D%20log%20%5C%20m%5Ea%20)
Applying this to LHS , we have ;
![\longrightarrow log_5 x^2 = log_5 4](https://tex.z-dn.net/?f=%5Clongrightarrow%20log_5%20x%5E2%20%3D%20log_5%204%20)
Now the bases of logarithm on LHS and RHS is same . On comparing , we have ;
![\longrightarrow x^2 = 4](https://tex.z-dn.net/?f=%5Clongrightarrow%20x%5E2%20%3D%204%20)
Put square root on both sides,
![\longrightarrow x =\sqrt{4}](https://tex.z-dn.net/?f=%5Clongrightarrow%20x%20%3D%5Csqrt%7B4%7D)
Simplify ,
![\longrightarrow \underline{\underline{ x =\pm 2 }}](https://tex.z-dn.net/?f=%5Clongrightarrow%20%5Cunderline%7B%5Cunderline%7B%20x%20%3D%5Cpm%202%20%7D%7D)
This is the required answer.
