Answer:
All terms of the equation were divided by 4.
Step-by-step explanation:
When we are given a equation, it is possible to multiply or divided all of the terms of the equation by a factor.
In this question:
We are given:
[tex]x + 4 = -12[/tex]
And end up with:
[tex]\frac{x}{4} + 1 = -3[/tex]
Which means that all terms of the equation were divided by 4.
- Kirk is reading a book and found that after 5 days he had read 180 pages.
rate is Kirk reading the book in (b) If the book is 765 pages long, how many
days will it take him to read the book at
the rate you found in (a)?
Answer:
21.25 days
Step-by-step explanation:
We first need to find the rate that he read the book for the first 5 days:
180 (pages)/5 (days)= 36
So he reads 36 pages a day. Now we need to find how many days it will take him to read the whole book, while reading 36 pages a day.
765 (total pages)/36 (pages he reads in a day) = 21.25

You are facing South. You make an about face, then turn 90 degrees right. What direction are you facing?
If you face South, perform an about face (180-degree turn), and then turn 90 degrees to the right, you will be facing West.
If you are facing South and make an about-face, then turn 90 degrees right, you will be facing West. This is because an about-face means to turn around 180 degrees, so you would now be facing North.
Then, turning 90 degrees to the right from the North would put you in the direction of the West. To summarize, if you start off facing South, making an about-face means turning around 180 degrees to face North.
From there, turning 90 degrees to the right puts you in the direction of the West. Therefore, you would be facing West after making an about-face and turning 90 degrees to the right.

Answer:
x = -4.
n = -2.
v = -5.
Step-by-step explanation:
18 = -4x + 2
18 - 2 = -4x
x = 16/-4
x = -4.
6 + 2n = 2
2n = 2 - 6 = -4
n = -2.
5v + 8 = -17
5v = -17 - 8
5v = -25

Answer:
x = 4 and y = 1
Step-by-step explanation:
The given equations are :
2x+5y = 13 ...(1)
3x-2y = 10 ...(2)
We can use elimination method to solve the given equations.
Multiply equation (1) by 3 and equation (2) by 2.
6x+15y=39 ...(3)
6x-4y=20 ...(4)
Subtract equation (3) from (4).
6x-4y-(6x+15y) = 20-39
6x-4y-6x-15y = -19
-19y=-19
y = 1
Put the value of y in equation (1).
2x+5y = 13
2x+5=13
2x=8
x = 4
So, the solution of the given equations are x = 4 and y = 1.
