To add fractions, find the LCD and then combine.
Exact Form:1/2
Decimal Form: 0.5
So they can complete 1/2 of the task in a hour together
I believe the answer is 5t
6s7t-6s2t = 5t
Not knowing what you want, I'll arbitrarily choose to focus on the word problem:
Find the total cost of the blazers and pants, including the tax.
2 blazers @ $49.95 each comes to $99.90.
3 pair pants @ $17.50 each comes to $52.50.
Add these two products together: $99.90 + $52.50 = $152.40
Now mult. this result by 0.055 to find the sales tax: 0.055($152.400) =
$8.38
Finally, add together the purchase cost total and the sales tax:
$152.40 = $8.38 = $160.78 (answer)
You actually posted 3 problems, but not the instructions for the last two of them. That's why I focused on the word problem alone.
Answer:
To find the slope of the proportional relationship, use the slope formula. The slope formula is Y2-Y1/X2-X1. Plug in any two points into the equation and solve. I will use (8,10) and (12,15).
15-10/12-8
5/4
The slope of the proportional relationship is 5/4.
Hope this helps! :)
Answer:
only 2 packages of 1818 cookies
Step-by-step explanation:
If I want to buy only big packages
Then, i can buy exactly 3636 cookies buying 2 packages of 1818 cookies.
If i want to buy only mall packages
Then, there is no way to buy only small packages and get exactly 3636 cookies.
(with 55 packages i get 55x66=3630 and with 56 packages 56x66=3696)
If i want to buy a combination of both packages i can only buy one big package and the rest in small packages.
Then, there is no way to buy one big and the rest small packages and get exactly 3636 cookies.
(with one big package and 27 small packages we get 1818+27x66=3600 and with one big package and 28 small 1818+28x66=3666)
<em>T</em><em>hen</em><em>,</em><em> the only way to get 3636 cookies is with two packages of </em><em>1818</em><em>.</em>
