Answer:
3000
Step-by-step explanation:
it is very simple as the number's hundredth place is more than 5 , hence , it will be rounded up to nearest greater number.
in our case, it is 3000
Answer:
Step-by-step explanation:
y = kx
400 = kr . . . . . . (1)
also, r = 4k . . . .(2)
400 = k(4k) = 4k^2
k^2 = 400/4 = 100
k = sqrt(100) = 10
Answer:
x = 16
Step-by-step explanation:
10x = 105 - (12x - 247) //Distribute - sign
10x = 105 - 12x + 247 // Add 12x & combine like terms
10x + 12x = 352
22x = 352 //Divide 22
x = 352/22
x = 16
let L = length and let W = width.
Use the equations 2L + 2W = 2750
and L = 5W + 15
Then do the steps as follows -
1. Plug the equation for what L equals into the first equation
2(5W+15) + 2W = 2750
2. Then distribute the 2
10W + 30 + 2W = 2750
3. Then add like terms
12W + 30 = 2750
4. Then subtract 30 from both sides
12W = 2720
5. Divide by 12 on both sides
W = 226.67
6. Then plug that into the second equation
L = 5(226.67) + 15
L = 1148.35 should be the answer
