Answer:

The correct answer is A which is sine.

Step-by-step explanation:

The variable x is opposite to the known angle and the known side length which is the hypotenuse.

Recall the mnemonics SOH, which means that,
the sine ratio involves the length of the opposite side and the hypotenuse.

That is,

\sin50\degree=\frac{opposite}{hypotenuse}

\sin50\degree=\frac{x}{2}

We can use this to solve for x.

Find the solution set of the inequality:<br> -3x + 8 &lt; 15
telo118 [61]

Hello from MrBillDoesMath!

Answer:

x > -7/3

Discussion:

-3x + 8 < 15                             => add 3x to both sides

(-3x + 3x) + 8 < 15 + 3x          => (-3x + 3x) = 0

8 < 15 + 3x                              => subtract 15 from both sides

8-15 < 3x                                 => 8 - 15 = -7

-7 < 3x                                     => divide both sides by 3

-7/3 < x

Thank You,

MrB

Today, everything at a store is on sale. The store offers a 20% discount.
kotykmax [81]

Answer:

a) $19.2

b) 0.8x

c) $17.5

Step-by-step explanation:

1. We want to find the discount price given the regular price

The discount is 20%

so the discount price will be;

24 - 20% of 24

24 - 4.8 = $19.2

b) We have this as;

x - (20% of x)

x - 0.2x = 0.8x

c) let the original price be x

x - 20% of x = 14

x - 0.2x = 14

0.8x = 14

x = 14/0.8

x = $17.5
