Answer:
Step-by-step explanation:
Solve for 'x'.
To solve for 'x', isolate 'x'.
2.8a + 3.2x + 1 = 16.6
Subtract 1 from both sides. {Subtraction property of equality}
2.8a + 3.2x = 16.6 - 1
2.8a + 3.2x = 15.6
Subtract 2.8 a from both sides.
3.2x = 15.6 - 2.8a
Now, divide both sides by 3.2. {Division property of equality}
The slope of the line is 1.
Find the slope intercept form equation by using the point slope formula which is y=x+1;)
The tens digit of 31 is 3. There are 3 tens in this number and that is equal to 30. Also, the ones digit of this number is equal to 1. The answer to this item are therefore 30 and 1. Hope This Helps! :)

In calculating this, you would have to find the unit price first.
$13 per 3 1/4 yards is also equal to $4 per yard.
Then you would have to find out the other ones' unit prices.
a) $16 per 4 2/3 yards is equal to around $2.82 per yard, so <u>No</u>
b) $11 per 2 3/4 yards is equal to $4 per yard, so <u>Yes</u>
c) $26 per 6 1/2 yards is equal to $4 per yard, so <u>Yes</u>
I solved these by dividing the amount of money by the amount of string.
