Answer:
The consultant sold 15 circular stones and 22 rectangular ones
Step-by-step explanation:
let quantity of circular stones be X , rectangular ones be Y
thus:,We can deduce that,
26x+34y=1138...... equation 1
He sold total of 37 ,both stones
x+y=37... equation 2
Solving simultaneously
make Y subject of the formula in equation 1
34y=1138-26x
Answer:
8 family members. Average of 2.6 fish per person.
Step-by-step explanation:
How many family members caught fish? Count only those members who caught at least 1 fish (that's all of them, because nobody caught 0 fish!).
3 + 1 + 0 + 4 = 8 family members.
Average number of fish caught <u>per person</u>. This is the total number of fish caught divided by the total number of people.
This is a little bit tricky because, for example, 4 people caught 4 fish, making 4 x 4 = 16 fish caught.
Multiply number of fish (column 1) by the number of people (column 2):
1 x 3 + 2 x 1 + 3 x 0 + 4 x 4 = 3 + 2 + 0 + 16 = 21 fish caught.
21 fish. 8 people. On average, that is 21 / 8 = 2.625 which rounds to 2.6 fish per person.
Hint: the word "per" means <u>divide</u>, so "fish per person" tells you to divide the total number of fish by the total number of people.
Good Luck!
The class needs to sell at least 20 tickets
Let x be the number of tickets that need to be sold in order to add up to $1000
Using the equation $700+$15x>=$1000
Subtract 700 from both sides and then divide each side by 15 to get 20.
