Answer:
S = 6
R = 10
Step-by-step explanation:
Givens
Let the Regular Tickets be R
Let the Senior Citizen tickets be S
Equations
85r + 24s = 994 (1)
45r + 12s = 522 (2)
Solution
Multiply equation 2 by 2
- 2(45r + 12s = 522)
- 90r + 24s = 1044 Subtract (1)
- <u>85r + 24s = 994</u>
- 5r = 50 Divide by 5
- 5r/5 = 50/5 Do the division
- r = 10
======================
Solve for s
- 45r + 12s = 522 Substitute r = 10
- 45*10 + 12s= 522 Simplify the left
- 450 + 12s = 522 Subtract 450 from both sides
- 450-450 + 12s = 522-450 Simplify
- 12S= 72 Divide by 12
- 12S/12 = 72 Do the division
- S = 6
something is wrong on your question
ie 6x^ is there a missing number
Answer:
Step-by-step explanation:
first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm
a = 48
b= 30
Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]
= 1/2*30√( 48² - 1/4×30²)
=1/2*30√ (2304 -225)
=684sq cm
cost required to make umbrella= 10*684*5
= 3<em>4200</em>
