Find the value of y.

Alexandra [31]

Answer. First option: -1

Solution:

We have a triangle, and we know two angles of 60° each one. We can find the third angle A, using:

A+B+C=180°, with B=60° and C=60°:

A+60°+60°=180°

Solving for A: Adding similar terms:

A+120°=180°

Subtracting 120° both sides of the equation:

A+120°-120°=180°-120°

A=60°

The third angle A is 60° too, then the triangle has three equal angles of 60° each one, and it is an equillateral triangle, thus its three sides must be congruents:

2y+6=4=2x-3

We need to find the value of y, then using the first equality:

2y+6=4

Solving for y: Subtracting 6 both sides of the equation:

2y+6-6=4-6

2y=-2

Diniding both sides of the equation by 2:

2y/2=-2/2

y=-1

You have a coupon for $15 off a video game. You can use it on 2 separate days.

iogann1982 [59]

a) Original price of the game is $ 37.99

b) Percent of discount is 39 %

c) Original price is $ 27.99

d) Percent of discount is 54 %

Solution:

You have a coupon for $15 off a video game

a) On Monday, the discounted price of your video game is $22.99

Therefore,

Discount price = $ 22.99

From given,

Discount rate = $ 15

Therefore,

Original price = Discount price + Discount rate

Original price = 22.99 + 15 = 37.99

Thus original price of the game is $ 37.99

b. What is the percent of discount to the nearest percent?

Let "x" be the percent of discount

Then, we can say,

x % of original price = discount rate

x % of 37.99 = 15

$\frac{x}{100} \times 37.99 = 15\\\\x \times 37.99 = 1500\\\\x = \frac{1500}{37.99}\\\\x = 39.48 \approx 39$

Thus percent of discount is 39 %

c. On Thursday, the discounted price of your video game is $12.99

Original price = 12.99 + 15 = 27.99

Thus original price is $ 27.99

d. What is the percent of discount to the nearest percent?

Let "x" be the percent of discount

Then, we can say,

x % of original price = discount rate

x % of 27.99 = 15

$\frac{x}{100} \times 27.99 = 15\\\\x \times 27.99 = 1500\\\\x = \frac{1500}{27.99}\\\\x = 53.5 \approx 54$

Thus percent of discount is 54 %
