Answer:
35 hotdogs
Step-by-step explanation:
You are running a concession stand at a basketball game. You are selling hotdogs and sodas.
Let the number of hot dogs be represented by x
The number of soda be represented by y
You sold a total of 87 hotdogs and sodas combined
x + y = 87
x = 87 - y
Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.
Hence we have the equation:
$1.50 × x + $0.50 × y = $78.50
1.50x + 0.50y = 78.50
Substitute 87 - y for x
1.50(87 - y) + 0.50y = 78.50
130.5 - 1.50y + 0.50y = 78.50
Collect like terms
- 1.50y + 0.50y = 78.50 - 130.50
-1.00y = -52
y = -52/-1
y = 52 sodas
How many hotdogs did you sell?
Using the equation:
x = 87 - y
x = 87 - 52
x = 35 hotdogs
Hence, you sold 35 hotdogs
You have to find a common denominator for the fractions. 5 and 7 both go into 35 which is the lowest common multiple of 5 and 7. 2/5 is multiplied by 7/7 and 3/7 is multiplied by 5/5. Then add the two fractions. So 29/35 parts are finished of the total number of bracelets.
1st
90+55+x=180 (Angles inside a triangle equal 180 degrees) Solve for x
x = 35 degrees
2nd
2 non-adjacent angle in a triangle is equal to the exterior angles, therefore
25 + x + 15 = 3x + 10 Solve for x
40 + x = 3x + 10
-10 -1x -1x -10
<u>30 = 2x</u>
2
x = 15 degrees
Therefore angle ABC is x + 15 where x + 15
Therefore angle ABC = 30 degrees
Who ever hand wrote in those degrees/equations didn't really think it out because < A + <B should be greater than 90 not less than 90
