Answer:
n = -4
Step-by-step explanation:
−5(n+3)=6(n+4)+5
Step 1: Simplify both sides of the equation.
−5(n+3)=6(n+4)+5
(−5)(n)+(−5)(3)=(6)(n)+(6)(4)+5(Distribute)
−5n+−15=6n+24+5
−5n−15=(6n)+(24+5)(Combine Like Terms)
−5n−15=6n+29
−5n−15=6n+29
Step 2: Subtract 6n from both sides.
−5n−15−6n=6n+29−6n
−11n−15=29
Step 3: Add 15 to both sides.
−11n−15+15=29+15
−11n=44
Step 4: Divide both sides by -11.
−11n
−11
=
44
−11
n=−4
Answer:
20
Step-by-step explanation: -13 to 7 think about that. We have to add 13 to make it 0. Then we add 7. So 13 plus 7 is 20. Enjoy :)

Answer:
It will take 4 years
Step-by-step explanation:
The formula of the simple interest is <em>I = Prt</em>, where
- <em>P</em> is the investment
- <em>r</em> is the annual rate in decimal
∵ The investment is $40000
∴ <em>P</em> = 40000
∵ The simple interest is $8000
∴ <em>I </em>= 8000
∵ The rate of interest is 5%
∴ r = 5%
→ Change it to decimal by divide it by 100
∴ <em>r</em> = 5 ÷ 100 = 0.05
→ Substitute them in the formula above
∵ 8000 = 40000 × 0.05 × t
∴ 8000 = 2000t
→ Divide both sides by 2000
∴ 4 = t
∵ t is the time of investment
∴ It will take 4 years
