Two numbers add to 436 and the front is 134 bigger than the second. What are the two numbers?
2 answers:
Take away 134 from the total, so that both numbers are of equal value:
436 - 134 = 302
Divide by 2 to find the smaller number:
302 ÷ 2 = 151
Add back the 134 to find the bigger number:
151 + 134 = 285
Answer: The two numbers are 151 and 285
Lets say x is the smaller number and y is the bigger number.
x + y = 436
x + 134 = y
We can substitute the second equation into the first (substitute x + 134 in for y)
x + (x+134) = 436
2x + 134 = 436
2x = 302
x = 151
We can now plug this back into either formula (i use the second)
151 + 134 = b
b = 285
The 2 numbers are 151 and 285

We can solve this by understanding that the area is maximized by a square
Therefore L=w.
p=2w+2w=520=4w
w=130

A=wL=130(130)= 16900 square yards</span>
Answer:
5–3 = 2
8–5 = 3
12–8 = 4
17–12 = 5
x-17 should be 6, hence x = 6+17 = 23.
