Answer:
He spend on bus fares £7.50
Answer:
C. x=3
Step-by-step explanation:
Because the sides are proportionate to each other
Side 3 is 3x the length of Side 1
Therefore,
Side 9 is also 3x the length of side X
3x=9
Divide both by 3
and X will be 3.
X-y=7
so you have to rewrite the equation in the form of mx+b=y
so ... x-y=7
-x -x
-y=7-x then simplify
-y(-y)=-(7-x) multiply both sides by -1
y=-7+x
which is the same y= x-7
y=x+-7
It would be:
5n - 2
