The Value Of X To The Nearest Tenth Is 2.5
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let's help out by giving some values to the question.
Let's say there are 230 students in a school. This number is 15% more than it was last year. Calculate the number of students last year.
Let the number of students last year be x.
Since there's a 15% increase, this implies that (100% + 15%) = 115% of x equals to 230. This will be:
115% of x = 230
115% × x = 230
115/100 × x = 230
1.15x = 230
x = 230/1.15
x = 200
There were 200 students last year.
Just assign the missing values and use the above method and you'll get your answer.
Your goal of this problem is to find the total amount of cards and stamps and then subtract 35 stamps from that number.
To do this, you first must find your total stamps.
3 binders x 25 stamps = ________ Total Stamps
Now find your total cards.
5 binders x 24 cards = ________ Total Cards
Now take these two totals and add them to find your grand total of items.
______ Total Cards + _______Total Stamps = ________ Grand Total
Now take your grand total and subtract 35 from it to find your answer.
_______ Grand Total - 35 stamps = _______Answer!!! :)

Answer:
6.7 days
Step-by-step explanation:
If t is the time the faster roofer takes, then the slower one takes 3t. Their combined rates in roofs per day are ...
1/t + 1/(3t) = 1/5
4/(3t) = 1/5 . . . . . . combine terms
t = 5(4/3) = 20/3 ≈ 6.7 . . . . multiply by 5t
The faster roofer working alone can roof a house in about 6.7 days.
