Answer:

The length of AB is 7.45 units.

Step-by-step explanation:

You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :

θ = 20°

adj. = 7 units

hypo. = AB

cos 20° = 7/AB

AB = 7/cos 20°

= 7.45 units (3s.f)

Gavin thought he was making a good investment when he heard about an online grocery company. So he bought 500 shares in the comp

kirill [66]

The answer would be D) 98.8% because if the initial price is $25 per share, then Gavin would have spent $12,500. None of the other answers make sense since if it was just 3% or 82.3%, then it would be too much to equal $150 in return. If you were to put C, then the shares would equal $4.43 each, and If you bought 500 shares, then it would equal $2,212.5 which would be way more than $150. In the other hand, D is correct because then only 1 share would equal $0.3 and that multiplied by 500 equals precisely $150.

Hope this helps!

Yo! Solving linear equations with integers! These are just some practice exercises I need help with! So they should probably be

drek231 [11]

Answer:

Step-by-step explanation:

<h3>Solving linear equation with one variable:</h3>

1) -4 + 3x = 4x - 8

Add 4 to both sides

-4 + 3x + 4 = 4x - 8 + 4

3x = 4x - 4

Subtract 4x from both sides,

3x - 4x = -4x + 4x - 4

-x = -4

$\sf \boxed{\bf x = 4}$

2) -5x - 8 = 2

Add 8 to both sides

-5x - 8 + 8 = 2 + 8

-5x = 10

Divide both sides by (-5)

$\sf \dfrac{-5}{-5}x =\dfrac{10}{-5}$

$\sf \boxed{\bf x = -2}$

3) 12r - 14 = 5(2-r)

12r - 14 = 5*2 - 5*r

12r - 14 = 10 - 5r

Add 14 to both sides

12r - 14 + 14 = 10 - 5r + 14

12r = 24 - 5r

Add 5r to both sides

12r + 5r = 24

17r = 24

Divide both sides by 17

r = 24/17

4) 3x - 8 = -(17 + 2x)

3x - 8 = -17 - 2x

Add 8 to both sides

3x - 8 + 8 = -17 - 2x + 8

3x = -9 - 2x

Add 2x to both sides

3x + 2x = -9

5x = -9

Divide both sides by 5

$\sf \dfrac{5}{5}x=\dfrac{-9}{5}\\\\\boxed{x = \dfrac{-9}{5}}$
