If you would like to know what is true about the solution of the set of equations, you can calculate this using the following steps:
2x + 2y = 18
x + y = 9 /*2
______________
<span>2x + 2y = 18
</span>2x + 2y = 18
______________
2x + 2y = <span>2x + 2y
</span>18 = 18
0 = 0
The correct result
would be infinitely many solutions.
Answer:
The unit rate at HEB is $0.23 per ounce. The unit rate at Fiesta is $0.25 per ounce. So HEB has the better buy for dish soap.
Step-by-step explanation:
To calculate unit rate, you divide the price by the oz.
So for HEB, you should do $2.80/12 oz. This will equal to $0.23 per ounce. For Fiesta, you should do $2.00/8 oz. This will equal to $0.25 per ounce.
To determine which one is the better buy, the lower priced one is better, meaning HEB is the better buy.
Point L because it is not in the same pattern as the others. It is on its own.
Same side, interior angles of parallel lines cut by a transversal are supplementary.
The sum of the measures of supplementary angles is 180.
Angles 4 and 6 are same side, interior angles, so their measures add to 180.
m<4 + m<6 = 180
109 + m<6 = 180
m<6 = 180 - 109
m<6 = 71
Answer: m<6 = 71 deg.
Presuming that I am reading the question correctly, the answer is D. A trigonometric table would provide all of the ratios of the sides in relationship to the angles. Sin, cos, and tan are just one example of the ratio.
