1. 39= 1 3/10b
⇒ 39= 13/10b
⇒ 39/ (13/10)= b
⇒ 30= b

2. 2/5g= 3/5
⇒ g= 3/5 / (2/5)
⇒ g= 3/2
⇒ g= 1 1/2

Final answer:
1. b= 30
2. g= 1 1/2

1. the answer is b = 30 .... you first simply both sides of the equation then flip it then multiply both sides by 10/13

2. the answer is g = 3/2 ...... multiply both sides by 5/2

Find x, y, and z. Multiple choice answers are below!

labwork [276]

Answer:

The correct answer is B. x ≈ 4.5, y = 5, z = 9

Step-by-step explanation:

1. We will use the Pythagorean theorem for solving for x, this way:

x² = 6² - 4²

x² = 36 - 16

x² = 20

x = √20

x = 2 √5 = 4.47 ≈ 4.5

2. For solving for y, we will do it this way:

There are only two possible options: y = 5, included in answer B or y = 9 as it is defined on answer C.

If we review it carefully, we will realize that y = 9 is not accurate because as we can see in the graph y + 4 = z and in this specific case, 9 + 4 ≠ 5 but it's true that 5 + 4 = 9.

Because of this reason, the correct answer is B. x ≈ 4.5, y = 5, z = 9
