Table for 1)
Beats 65 325 910
Minutes 1 5 14
2) $8.80 for 4 bags of chips
Explanation for 2)
8.8 divided by 4 equals 2.2
4.5 divided by 2 equals 2.25
Answer:
Number of Chicken Burritos purchased=7
Number of Cheesy Gordita Crunch purchased=6
Step-by-step explanation:
Let x be the number of Chicken Burritos and y be the number of Cheesy Gordita Crunch.
Total number items purchased=13
Total cost of 13 items=$28.17
Cost of each Chicken Burritos=$1.89
Cost of each Cheesy Gordita Crunch=$2.49
We have to find number of each items purchased.
According to question
.....(1)
...(2)
Equation (1) multiply by 2.49 and then subtract equation (2) from (1)


x=7
Substitute x=7 in equation (1)


Number of Chicken Burritos purchased=7
Number of Cheesy Gordita Crunch purchased=6
The measures of two complementary angles are 64 degrees and 26 degrees
<h3><u>Solution:</u></h3>
Let the larger angle be "a" and smaller angle be "b"
<em>Two angles are Complementary when they add up to 90 degrees</em>
so we get,
a + b = 90 ------ eqn 1
Given that measure of the larger angle is 12 more than twice the measure of the smaller angle
larger angle = 12 + 2(smaller angle)
a = 12 + 2b --- eqn 2
<em><u>Let us solve eqn 1 and eqn 2 to get values of "a" and "b"</u></em>
Substitute eqn 2 in eqn 1
12 + 2b + b = 90
12 + 3b = 90
3b = 90 - 12
3b = 78
<h3>b = 26</h3>
Therefore from eqn 2,
a = 12 + 2b
a = 12 + 2(26)
a = 12 + 52
<h3>a = 64</h3>
Thus the measures of two complementary angles are 64 degrees and 26 degrees
