It would be .75x=25-13
So .75x=12
x=16 because .75×16=12
When written in scientific notation, 3,900 = 3.9 x 10^3
6x + 4 - x = 2(x+1)
First combine like terms on the left side:
6x-x - 5x
So you have 5x+4 on the left side.
Then use the distributive property on the right side:
2(x+1) becomes 2x +2
Now you have 5x +4 = 2x +2
Subtract 4 from each side:
5x = 2x -2
Subtract 2x from each side:
3x = -2
Divide both sides by 3:
x = -2/3
Answer: <u>£21007.22</u>
Step-by-step explanation:
First, find the interest amount using the formula SI = (P × R × T) / 100.
- SI = interest amount
- P = principle amount = £18790
- R = interest rate(in percentage) = 5.9
- T = time(in years) = 2
SI = (P × R × T) / 100 = (18790 × 5.9 × 2)/100 = 221722/100 = £2217.22
The total amount = principle amount + interest amount
= £18790 + £2217.22 = <u>£21007.22</u>
17, because you divide 22 in half and add 6 because there are half as many mollies and there are 6 more guppies then goldfish.
