Answer:

x = -3

Step-by-step explanation:

3x + 4= -5

Subtract 4 from both sides.

3x = -9

Divide both sides by 3.

x = -3

First subtract 4 from both sides to isolate the 3x.

That leaves us with 3x = -9.

Since x is being multiplied by 3, to get x by itself,

we need to divide both sides of the equation by 3.

So our final answer is x = -3.

40 - 3k + 10k = -10 - 8k - 10

40 + 7k = -10 - 8k - 10

40 + 7k = -8k - 20

40 + 7k - 40 = -8k - 20 - 40

7k = -8k - 60

7k + 8k = -8k - 60 + 8k

15k = -60

15k/15 = -60/15

k = -4

Mary and Julie both have a goal of raising $1000 for charity. Mary raises $12 every 4 days. Julie raises $19 every 6 days.
baherus [9]
Julie would reach her goal first. Julie would reach her goal in approximately 316 days while it would take Mary approximately 333 days to reach it.

I know this because the steps to solve the problem are:

1.) 1,000/12 = 83.333 (to find how many days it would take her everyday)

2.) 83.333x4 = 333 (multiplying the answer by four makes it every four days)

3.) determine that it takes Mary 333 days

4.) 1,000/19 = 52.631 (just like step 1 but with different numbers)

5.) 52.631x6 = 316 (just like in step 2 but different numbers)

6.) determine it takes Julie 316 days

7.) 316 < 333 (takes Julie less time)

Answer: C

Step-by-step explanation:

I’m pretty sure it’s c because x isn’t less than -2. It goes forever in the directions of positive and negative infinity

The diagram below shows several parking spots near the grocery store, formed with three parallel line segments and a transversal
Marina CMI [18]
Something I noticed about angle 4, is that it shares a straight line with angle 3. (above it is a straight line)

A straight line equals 180 degrees.

So, angle 4 + angle 3= 180 degrees.

Angle 3 is congruent to angle 7.

180-132= Angle 7

180-132= 48

48 degrees is your answer.

I hope this helps!
