Answer:
10. First you multiply both sides by 3, making it 2x + 5 = 24
Then you subtract 5 from both sides making it 2x = 19
You dive both sides by 2 making x = 9.5
The answer is x = 9.5
11. First you need to find how much you need to pay each year. 12,000 x 0.05
you can make it easier by changing it to 120 x 5 = 600
You need to pay that for three years so 600 x 3 = 1800
Plus you need to pay the original money. 12,000 + 1,800 = 13,800
The answer is $13,800
12. First you change kilometers into centimeters. 172 km is 172,000 meters. 172,000 meters is 17,200,000
Then, you need to do 17,200,000 ÷ 500,000 but you can make it simple and do 172 ÷ 5 = 34.4
The answer is 34.4 cm
Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.
let's suppose x is the shortest leg of the triangle
The perimeter of the flower bed is 3x+8 ft
the surface to be coverd by sod would be x×(x+7)/2 sqft
(x+8)(x+8)=(x+7)^2+x^2
x'2+16x+64=x'2+14x+49+x^2
x^2-2x=15
x×(x-2)=15
x=5
(15+8)×$4.23=$97.29 for fencing
32.5sqft×$12.72=$413.4 for the sod
Answer:
every other one
Step-by-step explanation:
to put it specifically rings, 2, 4 and 6
