Answer:
A =80.5 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
The base is 14 ft and the height is 11.5 ft
A = 1/2 * 14 * 11.5
A =80.5 ft^2
The discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.
Answer:
x=24/7
Step-by-step explanation:
3(x+2)+4(x-5)=10
3x+6+4(x-5)=10
3x+6+4x-20=10
7x+6-20=10
7x-14=20
7x=24
x=24/7
