Answer:
Costco
Step-by-step explanation:
2 bottles at Costco give you 24 oz of shampoo for the price of $2.08, which is less than Wal-Mart's price of $2.20 for fewer ounces.
Costco has the better buy.
It’s D that is the answer
Answer:
Step-by-step explanation:
It appears to be the last step there that has evaded you. In the second line of work, you can see that what's in each set of parenthesis is exactly the same. Because of this, it is common and can be factored out. What's left is the 4x and the +5:
(5x - 3)(4x + 5)
That's factoring by grouping. It only works with polynomials that have an even number of terms so you can group them together in 2's.
Answer:
h = 3v/b
Step-by-step explanation:
Here, we want to select the equation that solves for h
What this simply means is that we should make h the subject of the formula
Thus, we have 3 * v = bh
3v = bh
h = 3v/b
Let x be the number of children and t, the number of adults.
x + y =153
5.2x + 8.4y = 1013.2
Solving those equation will give:
x = 85 tickets sold to the kids ( and 68 tickets for adults)
