Answer:
6. Multiply 2 by 6
7. 71 + 9(8) = 71 + 72 = 143
8. 52 + 3(4) = 12 + 52 = 64
9. 19.25 + 2.75(7) = 19.25 + 19.25 = 38.50
10. 2(0.6)^2 + 4(0.6)(5) = 0.72 + 12 = 12.72
Srry if they r wrong
Answer:
8+6n
Step-by-step explanation:
First, distribute the 2 into the parenthesis.
2(6)+2(3n)-4
Then, multiply the numbers.
12+6n-4
Now add(subtract in this case) the common multiples.
12-4= 8
8+6n
Since you can no longer simplify the equation, this is the answer..
8+6n
Exponential growth is
F=P(1+r)^t
F=future amount
P=present amount
r=rate
t=time in years
rate=2%=0.02
therefor the equation is
f(x)=23,000(1+0.02)^x
f(x)=23,000(1.02)^x
where x=time in years from 2012
To convert mixed number fractions you can:
→ Convert them into improper fractions
→ Give the fractions common denominators
→ Subtract the two numerators, keeping the denominator
→ If necessary, simplify and convert your fraction back to a mixed number fraction
Example: 3 5/6 - 1 2/3
→ 23/6 - 5/3
→ 23/6 - 10/6
→ 13/6 = 2 1/6
∴ 3 5/6 - 1 2/3 = 13/6 OR 2 1/6
