Pls help meee brainliest

Step-by-step explanation:

6  + 11            First add the whole numbers together

6 + 11 = 17          Now add the fractions

+      Find a common denominator

Since 2 gos into 4, multiply by

x =

+ =

17 + = 17

You can also convert to a decimal, then add.

6  = 6.25

11 = 11.5

6.25 + 11.5 = 17.75

.75 as a fraction is

so 17 ft

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

you never say the total so we cant find the percentage used for petrol
