Answer:

x = 28.8

Step-by-step explanation:

Using the Sine rule in the triangle then

$\frac{43}{sin87}$ = $\frac{x}{sin42}$ ( cross- multiply )

x × sin87° = 43 × sin42° ( divide both sides by sin87° )

x = $\frac{43sin42}{sin87}$ = 28.8

I want to earn $42,000 for a new car, I have 12,678, How much more money do I need to buy the car?

So, you have $12,678. However, you want to earn $42,000 for a new car. If you want to figure out how much money you need, you need to subtract the number of money you want to earn by the number of money that you already have:

$42,000 - 12, 678 = 29,322$

You would need $29,322 more in order to buy the car.

1.1 Pull out like factors :

-8x - 2 = -2 • (4x + 1)

2.1 Divide both sides by -2

Remember to flip the inequality sign:

2.2 Divide both sides by 4

x+(1/4) ≥ 0

Solve Basic Inequality :

2.3 Subtract 1/4 from both sides
