a=9.4 b=12.0

Step-by-step explanation:

You need to use Pythagorus

So for a:

8²+5²=89    a=√89=9.4

And b:

17²-12²=145 b=√145=12.0

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

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
