<u>Step 1: Solve for x</u>

x + 3x + 2x = 180

6x / 6 = 180 / 6

x = 30

<u>Step 2: Find the measure of angle C</u>

Angle C = 2x

Angle C = 2(30)

Angle C = 60 degrees

A student has $1 bills and $5 bills in his wallet. He had a total of 15 bills that are worth $47. How many of each type does he

Mrrafil [7]

Total number of $1 bills=7

Total number of $5 bills=8

Further explanation:

Given

Let x be the number of $1 bills

and

y be the number of $5 bills

Then according to the given statements

x+y=15

x+5y=47

From first equation:

$x+y=15\\x=15-y$

Putting x=15-y in second equation

$x+5y=47\\15-y+5y=47\\4y=47-15\\4y=32\\\frac{4y}{4}=\frac{32}{4}\\y=8$

Putting y=8 in first equation

$x+8=15\\x=15-8\\x=7$

Hence,

Total number of $1 bills=7

Total number of $5 bills=8
