5A) Lines x and y are parallel. Write an equation that represents the relationship between band e.

b + e = 180°

Step-by-step explanation:

lines x and y are parallel. Therefor angles b and c are allied angles. That means;

b + c = 180°

Furthermore, angle c = angle e. (they're vertically opposite angles)  

b + c = 180° (Proved above)

c = e (Proved above)

∴ b + e = 180°

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
