Lol is it hard I don’t get it are you okay 2+2=4 -1=3 quick maths
1. 2-1+5x4x11
5x4=20
2-1+20x11
20x11=220
2-1+220
2-1=1
1+220=221
2. 14/2-1+3
14/2=7
7-1+3
7-1=6
6+3=9
3. 3x8x2-42+5
3x8=24
24x2-42+5
24x2=48
48-42+5
48-42=6
6+5=11
Answer:
The equivalent to one over five m − 20 is one over five (m − 100) ⇒ B
Step-by-step explanation:
Let us solve the question
∵ One over five means 
∴ One over five m - 20 =
m - 20
→ By using the distributive property, take one over five as a common factor
from both terms
∴
m - 20 =
- 
→ Simplify the bracket
∵
m ÷
=
m × 5 = m
∵ 20 ÷
= 20 × 5 = 100
∴
-
=
(m - 100)
∴
m - 20 =
(m - 100)
The equivalent to one over five m − 20 is one over five (m − 100)
We have that every quarter, he will get an 0.8% interest rate. We also have that there will be 14*4=56 periods of repayment. We have that by the formula, if there are n periods and x% is the interest rate, the capital is multiplied by (100+x%)^n.
Suppose Micah invests x money. Then, we have that after 14 years, the capital available will be C=

. We have that C=18500$ and hence that 18500=x*1.562. Thus, solving for x we have that x=11841$.
Micah will need to invest only 11841$ in order to pay for his boat; this shows the importance of saving since he earns a lot of money, around 7k $.
