He rounded the percent to 40% and the number to 200.
Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15

Answer: A) The product is rational</h3>
Explanation:
The number 4.56 is rational because any terminating decimal can be written as a fraction of two integers. For example, 4.56 = 456/100
The number is the same as where the '5's go on forever. Repeating decimals like this are rational. It turns out that which you can find through trial and error, or apply a bit of algebra. I'll skip showing those steps unless you need me to go over them.
Because both given numbers are rational, multiplying those two rational numbers will lead to another rational number
rational times rational = rational
I'll skip over the proof of this as well unless you need me to show it.
