Equation identically true
Answer:
78
Step-by-step explanation:
Average income from Sunday to Thursday = Rs 75.
There are 5 days .
So average = sum / 5
= sum = 5 average
= sum = 5 × 75
= sum = 375
He earns Rs 93 on Friday .
So adding this sum = Rs 375 + 93
= Rs 468
Average = sum / number of terms
= Average = 468/6
= Average = 78
Hence the average is 78 .
Answer:
x+12
Step-by-step explanation:
Answer:
x <= 8 ... you can buy a max of 8 fishes
6 books or more per month.
Step-by-step explanation:
Given the information provided, we can create the following inequality which multiplies the cost per fish ($7) by the number of fish we can buy (x) and it has to be less than or equal to $56
7x <= 56
We can now solve this inequality by isolating x
7x <= 56 ... divide 7 on both sides
x <= 8 ... you can buy a max of 8 fishes
-----------------------------------------------------------------------------------------------------------------
13x > 68 ... divide both sides by 13
x > 5.23
Since the number of books needs to be a whole number then we round this decimal up to 6. Meaning that you must read 6 books or more per month.
