C is your answer. 5x + 2 = 17
First let’s get them all in terms of x:
Box kites = 3x
Dragon kites = x + 2
Butterfly kites = x
Adding all those up:
x + 3x + x + 2 = 17
Combine like terms:
5x + 2 = 17

She can give 7.29 ft or 7.3 ft of yarn to her 17 students given that the total measurement of the yarn is 124 ft.
solution:
124ft/17students - the operation used is division, dived 124ft w/c is the measurement of the yarn by 17 students.
7.294117647058824 - simplify the answer by rounding it off, at least one or two decimal points; making it 7.29 ft or 7.3ft
FOIL is an 'acronym'. It helps you remember how to multiply
two binomials ... like (2x-7) and (5x+5) .
FOIL stands for "First, Outside, Inside, Last". Here's how it's used
to multiply these particular two binomials:
(2x - 7) (5x + 5)
First: (2x) (5x) = 10x²
Outside: (2x) (5) = 10x
Inside: (-7) (5x) = -35x
Last: (-7) (5) = -35
Add them all together, and you have the product:
10x² + 10x -35x -35
Simplify the sum: 10x² - 25x -35
or 5(x² - 5x - 7) .
x=#of hours worked
33 per hour or 33x (since 33 times every hour)
initial fee is independed of hours so
fee=33x+16
if fee=197 then solve for hours or x
197=33x+16
subtract 16 from both sides
181=33x
divide both sides by 33
5.4848484848=x
he worked 5.48 hours
