Answer 1

Answer:

140, 60

Step-by-step explanation:

15x+5 + < CDB =180 line form an 180 angle

180-80-6x-6 = < CDB sum of angles in a triangle is 180

substitute < CDB from second to first

15x+5+180 -80-6x-6 =180

combine like terms

9x -81 =0

x=81/9=9

so angle YDC = 15*9+5 = 140 degrees

and angle DBC = 6*9+6= 60 degrees

Katie wants to buy a motor scooter that costs $518. She has already
saved $188 and will earn $22 each week from babysitting jobs. Write and
solve an equation to see how many weeks it will take Katie to save
enough money to buy the motor scooter.

Answers

Answer:

$518-$188 = $330

$330 ÷ $22= 15

It will take Katie 15 weeks to save enough money.

Answer:

It will take Katie 15 weeks to save up for her motor scooter.

Step-by-step explanation:

Step 1: Analyze Data

First, you can recognize that Katie is going to make $22 each week, making that our slope. She has already saved $188, so that is our y-intercept since it is our 'start amount.' And then we are given one more number, $518, which is our y value since it is our 'goal.'

Step 2: Create an equation

[tex]518=188+22x[/tex]

Step 3: Solve for x

[tex]518=188+22x\\330=22x\\x=15[/tex]
