Answer: 30.5 and 35.5
Step-by-step explanation:
We can use a system of linear equations to find out the answer to this problem. The larger number will be x and the smaller number will be y.
x=y+5
x+y=66
Substitute y+5 in for the bottom equation to get y+5+y=66. Simplify to get 2y+5=66. Subtract 5 from both sides and get 2y=61. Divide by 2 to get y=30.5. This is the smaller number. Add 5 to get the bigger number, which is 35.5
Answer:
A
Step-by-step explanation:
An equation in the form y=kx represents something increasing at a constant <u>rate</u>
(s + 3t) * (2s - 2t) = 2s^2 - 2st + 6ts - 6t^2
