Answer:
x=3
Step-by-step explanation:
Well if 4x>10, then x needs to be more than 2.5, (because 2.5*4=10) So the only answer left is x=3
2X^2+4X-8-X^2+6X-4
X^2+4X-8+6X-4
X^2+10X-12
I believe 22. Because 11+3=14, but without that, you would add 11 to 11, which gives you 22
Answer:
2,070,281
Step-by-step explanation:
let x = number of years
let y = population
Given:
- initial population = 500000
- rate of increase = 7%
y = 500000 × 1.07^x
when x = 21:
y = 500000 × 1.07^(21) = 2070281.187... = 2,070,281
Answer:
x is equal to 15.
Step-by-step explanation:
In order to solve this, we need to set it up as a proportion.
6/8 = x/20
Now that we have the proportion, we need to cross multiply to solve.
6*20 = 8*x
120 = 8x
15 = x
