Answer:
A. 7 burritos for $51.50
Step-by-step explanation:
22.50/3=7.50
1 burrito cost $7.50
2 burritos will cost $15.00
2×7.50=15
5 burritos will cost $37.50
5×7.50=37.50
4 burritos will cost $30.00
4×7.50=30.00
However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50
Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54
To calculate the mean weights of the potatoes, the weights are all added and divided by the number of potatoes.
The sum of all the potatoes - <span>5 + 8 + 9 + 11 + 7 + 7 + 8 + 9 + 12 + 7 = 83
the number of potatoes - 10
we have to divide the sum of weights by 10
Mean weight = 83/10 = 8.3
Rounded off to the nearest ounce - 8 </span>ounces
