Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.
natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.
integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.
rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.
irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.
so your answer is integer and rational, hope this helped! :)
Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
Water was pumped out in t-hours.
Time t would be the domain, 0 to t.
First we can add 150 + 50 = 200.
Then we can subtract 75 from that to get 125.
Now our equation is 125 + ? = 0.
What we have to do is add -125 to get zero.
So ? = -125.
Hope this helps!
Answer:
B. Infinitely many
Step-by-step explanation:
5x+48+7x=12(x+4)
multiply 12 to x and multiply 12 to 4
5x+48+7x=12x+48
add 5x to 7x
12x+48=12x+48
the equation of both sides are the same since both equations are the same, the answer is infinitely many.
