One number is 4 more than another, and their sum is 60. What is the smaller number?
ivanzaharov [21]
According to your question, there are 2 unknown numbers mentioned. Let the 2 unknown numbers be represented by the variables x & y, then x is considered to be one of the numbers being more than y by the addition of 4, .ie. x = 4 + y --- (1) The sum of the 2 numbers is 60, i.e. x + y = 60 --- (2) To find the smaller number, we solve eqn (1) & (2) using the concept of substitution, i.e. substitute 4 + y for x in eqn (2), i.e. 4 + y + y = 60 4 + 2y = 60 2y = 60 - 4 2y = 56 y = 28 ...Ans. Recall that x is more than y by 4, then 28 is the smaller number.

Answer: A, 102

Step-by-step explanation:

Okay so just find the big square and subtract the holes

big square is 30x20 which is 600

hole #1 is 20x5 = 100

hole #2 is a triangle so you first find the base and height which are 10 and 5 respectively. Then use the triangle area formula a = 1/2bh to find that the triangle's area is 25.

Subtract the holes now

600-100-25 = 475

1 Gallon = 200 square feet covered so divide 475 by 200 to find how many gallons should be used. It's 3 gallons since you can't just buy a fraction of a gallon (Unless your being weird).

One gallon is 34, so 3 gallons is 3*34 = 102

Or in other words... A

hope you learned and can incorporate these methods for future problems :D!
