A television with a price of
$300\$300
$300
dollar sign, 300
is to be purchased with an initial payment of
$60\$60
$60
dollar sign, 60
and weekly payments of
$30\$30
$30
dollar sign, 30
. Which of the following equations can be used to find the number of weekly payments,
ww
w
w
, required to complete the purchase, assuming there are no taxes or fees?
Choose 1

(Choice A)
A

300=30w−60300 = 30w - 60
300=30w−60
300, equals, 30, w, minus, 60

(Choice B)
B

300=30w300 = 30w
300=30w
300, equals, 30, w

(Choice C)
C

300=30w+60300 = 30w + 60
300=30w+60
300, equals, 30, w, plus, 60

(Choice D)
D

300=60w−30300 = 60w - 30
300=60w−30

C. 300=60+30w

Step-by-step explanation:

Given:

Price of television-$300

Initial Payment-$60

Weekly payments-$30

Let weekly payments be w:

The initial payment plus the weekly installments should be equivalent to the television price:

The number of weekly payments is 8 weeks and the equation to solve for w is

300=60+30w

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
