Answer:
11
/20
Step-by-step explanation:
Step 1- We can't subtract two fractions with different denominators. So you need to get a common denominator.
So we multiply 3 by 10, and get 30.
Then we multiply 2 by 4, and get 8.
Next we give both terms new denominators -- 4 × 10 = 40.
So now our fractions look like this:
30
/40
−8/40
Step 2- Since our denominators match, we can subtract the numerators.
30 − 8 = 22
So the answer is:
22
/40
Step 3-
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? Yes we can!

/20 is the answer
Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.
he usually plans to stop and rest for about 5 minutes.
m represents the total minutes.
12 calories per minute.
for m minutes the calories burn is 12m
He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes
So expression becomes 12(m-5)
He wants to burn 540 calories. So we set the calories = 540
The equation becomes ,
12(m-5) = 540
Now we solve for m , total number of minutes
12(m-5) = 540(divide by 12 on both sides)
m - 5 = 45
m = 50 ( add 5 on both sides)
Anzelm should plan to be out jogging for 50 minutes

Answer:
option (B) 20
Step-by-step explanation:
Data provided in the question:
Number of photographs initially sold = 20
selling price of first 20 photographs = $10 each
Therefore,
Revenue from 20 photographs = 20 × $10 = $200
Selling price of further photographs = $15
Let the number of additional photographs sold be 'x'
thus,
total revenue = $200 + $15x
now,
according to the question
80% of ($200 + $15x) = $400
or
0.80 × ($200 + $15x) = $400
or
($200 + $15x) = $500
or
$15x = $300
or
x = 20
Hence,
the answer is option (B) 20
Answer:
The measure of the missing side length = 45
Step-by-step explanation:
Pythagorean Theorem states: A² + B² = C²
28² + B² = 53²
784 + B² = 2809
B² = 2809 - 784
B² = 2025
B = 
B = 45
Therefore the measure of the missing side length = 45
Hope this helps!
