Answer:
Some rational numbers are natural numbers
All whole numbers are integers
Some integers are natural numbers.
Step-by-step explanation:
B
Explanation:
A Variable is a symbol for a number we don't know yet. We don’t know the number of colors on the page.
N = number of hours.
$5 per hour, total = 5*n = $5n
Since $35 has been saved.
The amount saved plus the amount got from baby sitting should be greater or equal to the $90 cost.
5n + 35 ≥ 90
5n ≥ 90 -35
5n ≥ 55
n ≥ 55/5
n ≥ 11
So Rodney should baby sit for at least 11 hours, that is 11 and above.
The original price was 725.
Explanation:
"36% less than" means taking 36% away from 100%. 100-36 is 64, so 64% remains when 36% is taken away. So, 64% of the original table's price is 464.
So, if the original price was x, 464=0.64x
Solve this by dividing both sides by 0,64:
725=x
So, the original price was 725.
I'm not quite sure if this is what you need, but I am going to solve these equations by elimination. x= 8/17 and y = 11/17 (8/17, 11/17).
