Lincoln is saving $360 to buy a new bike. he already has $85 and can earn $12 per hour at work. which of the following equation describes the number of hours, h, for which lincoln must work to earn enough money to buy the new bike?

Lincoln needs to work for 23hrs to have enough money to buy a new bike

Step-by-step expression

Lincoln is saving $360

He has $85

He can earn $12hr

12h + 85 = 360

12h + 85 = 360

-subtract 85 on both sides

12h = 275

-divide 12 on both sides

h = 22.91

h ≈ 23

12h + 85 = 360

12(23) + 85 = 360

276 + 85 = 360

361 ≈ 360

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
