Answer:
$72.80
Step-by-step explanation:
You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.
(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)
1/4 = 0.25
5/8 = 0.625
20% = 0.20
So now we have: 0.20 < 0.25 < 0.3 < 0.625 < 0.85
So the solution is 20%, 1/4, 0.3, 5/8, 0.85
Answer:
- Martin is 40 and Ada is 14
Step-by-step explanation:
- Martin's age = m
- Ada's age = a
<u>Martin is two years younger than three times his daughter Ada’s age:</u>
<u>The sum of their ages is 54:</u>
<u>Solving this equation for m:</u>
<u>Eliminate m:</u>
<u>Solve for a:</u>
- 3a + a = 54 + 2
- 4a = 56
- a = 56/4
- a = 14
<u>Find m:</u>
Martin is 40 and Ada is 14
Answer:
if f(x) = ax + b then f-1(x) = (x - b)/a
Step-by-step explanation:
Now
f(x)=ax + b
then y = ax + b
interchanging x and y , we get
or, x = ay + b
or, x - b = ay
or, (x - b)/a = y
therefore,f-1(x) = (x - b)/a
