Answer:

52°

Step-by-step explanation:

6x - 8= 4x + 12 \\ (exterior \: alternate \:  \angle s) \\  \\ 6x - 4x = 12 + 8 \\  \\ 2x = 20 \\  \\ x =  \frac{20}{2}  \\  \\ x = 10 \\  \\ 4x + 12 = 4 \times 10 + 12 \\  \\4x + 12  = 40 + 12 \\  \\ 4x + 12 = 52 \degree

Kenzie finds purple, blue, and silver space rocks while exploring, 2/3 of the rocks are purple and 3/4 of the remainder are blue
Nadya [2.5K]

Answer:

There were 36 space rocks in total.

Step-by-step explanation:

First, you need to find what fraction of the original rocks are silver.

If 2/3 are purple, then 1/3 of them are not.

If 3/4 of the remaining 1/3 are blue, then 3/4 x 1/3 = 3/12 rocks are blue.

2/3 of the rock are purple, 3/12 of them are blue, and the remaining is silver.

So, you need to do 2/3 - 3/12, then find common denominators so, 8/12 - 3/12 which = 1/12.

This means 1/12 of the rocks are silver. If there are silver rocks, you need to find a suitable equation that needs to be solved.

So:

1/12r = 3

r = 36 silver rocks

There were 36 space rocks in total.

hope this helps :)

M = 1/2 (0, -3)<br> Write the equation of a line using slope intercept form
marshall27 [118]

Answer:

y=\frac{1}{2}x-3

Step-by-step explanation:

slope intercept form is y=mx+b

b is y intercept

so we plug the coordinate into the equation

-3=\frac{1}{2}(0)+b

-3=b

so y intercept is -3

so we then write our equation which is,

y=\frac{1}{2}x-3
