Ok so in order to do this, you have to set up an equation. Let's make a=the score of the first test and b=the score of the second test. (You can choose different variables, it doesn't matter.) It says the sum of the two equals 170. So, a+b=170. It also says that the score of the first was 6 less than the second. This can be shown as a=b-6. Now you can plug this in for a in your original equation. It will look like:
(b-6)+b=170
You can solve for b.
2b-6=170
2b=176
b=88
Since you want a, plug into either equation for b. I'll use the second one.
a=88-6
So, a=82
Answer:
A) Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A solid blue point is placed on the 3rd tick mark to the left of 0. A solid, blue point is on the 3rd tick mark to the right of 0.
Step-by-step explanation:
Consider the provided number -3.
We need to determine the number line which shows the opposite of -3.
The Opposite numbers are numbers that are precisely the same length from 0, but on opposite sides, when put on a number line.
The opposite numbers are the same number except their sign.
The opposite number of -3 is 3.
The required number line is shown below:
Hence, the correct option is A) Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A solid blue point is placed on the 3rd tick mark to the left of 0. A solid, blue point is on the 3rd tick mark to the right of 0.
Answer:
-1/2
Step-by-step explanation:
You would do m which represents slope. So m = y2 - y1/x2-x1. I then plugged the points in and got -1/2. Did this help???
