Answer: a burger is $5.25, fries are $1.50
b = burger, f = fries
3b + 3f = 20.25
5b + 8f = 38.25
First, solve for b in terms of f
3b = 20.25 - 3f
b = 6.75 -f
Then substitute that for b in the other equation to solve and get a numerical value for f.
5(6.75 -f) + 8f = 38.25
33.75 -5f +8f = 38.25
33.75 + 3f = 38.25
3f = 4.5
f = 1.5
Now substitute that in to get a numerical value for b
b = 6.75 - 1.5
b = 5.25
Checking the math:
3b + 3f = 20.25
3(5.25) + 3(1.5) = 15.75 + 4.5 = 20.25
Answer:
6 x 4 = 24, 24 divided by 2 = 12(area of 1 triangle)
12 x 2(two triangles) = 24
5 x 6 = 30(area of 1 slanted rectangle)
30 x 2(two rectangles) = 60
6 x 6 = 36(area of bottom square)
Add all given AREAS:
24 + 60 + 60 = 144 mm2 is your answer.
If there is an odd number of data values then the median will be the value in the middle. If there is an even number of data values the median is the mean of the two data values in the middle. For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5. For the data set 1, 1, 2, 6, 6, 9 the median<span> is 4.
</span>The mean<span> is the average of the numbers: a calculated "central" value of a set of numbers. To calculate: Just add up all the numbers, then divide by how many numbers there are.</span><span>

Answer:
61°
Step-by-step explanation:
Since the angles make up a full circle which is 360°, deduct all the degrees with numbers from 360°
360 - 65 - 50 - 62 = 183
x + 2x = 3 x
3x = 183
x = 183 ÷ 3 = 61
