Cara's bill was $30.51 this week.
Cara's bill was $7.60 more than two-thirds of her grocery bill last week.
First thing we need to do therefore, is to find out what 2/3 of her bill was last week:
= 2/3 x 34.37
= $22.91
Her bill was $7.60 more than this amount so it was:
= 7.60 + 22.91
= $30.51
Cara's bill was therefore $30.51 this week.

15b+18=30+3b
15b=30+3b-18
15b=3b+12

12b=12
B=1
Answer: Quadrant I
Step-by-step explanation:
Since the x-axis contains the temperature in C degrees, then the temperature above 0 (meaning positive) would have to be on the right side of the x-axis. And the increase in Y is going upwards. Therefore, positive values for both X and Y are in the first Quadrant
I will try to make this as simple as possible.
First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:
1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)
With that being said, let's begin.
First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing
we have the equivalent of -0.3, so now we know it's a rational number.
As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:
-0.3 is a rational number, but 3.14144144414444 is not.
Hope this helped! c:
