Answer:
4
Step-by-step explanation:
The absolute value is just the positive version of a number so if you have like -28 the absolute value is just 28
9h + 3f = 24.75....multiply by 4
6h + 4f = 19.50 ...multiply by -3
----------------------
36h + 12f = 99 (result of multiplying by 4)
-18h - 12f = - 58.50 (result of multiplying by -3)
--------------------add
18h = 40.50
h = 40.50/18
h = 2.25 <== hamburgers cost 2.25 each
6h + 4f = 19.50
6(2.25) + 4f = 19.50
13.50 + 4f = 19.50
4f = 19.50 - 13.50
4f = 6
f = 6/4
f = 1.50 <== fries cost 1.50 per order
Answer:
30/81
Step-by-step explanation:
Multiplication should be used here. 30 tens means number ten should be added 30 times. 10+10+...+10 thirty times, which can be written as 10 x 30 which gives us the number 300. We get the same answer if the value of 10 thirties is required. We can use the same way to get the answer like the question given in the begging.
30/100
81/100
If you get 5L in 1 min, you will get 300 L in an hour
