The Smith family has three children: Tom, John, and Andy. Tom is younger than Andy. John is not older than Tom. From youngest to oldest, how are the children ordered by age?
Answers
Answer 1
Answer:
age of tom=t
age of john=j
age of andy=a
t<a
if j is not older than t, then he is less than or equal to t so
j ≤ t
but there is an oldest so therefor we assume that j < t
t < a
j < t
subsitute
j<t<a
andy is oldest
tom is second
john is youngest
age of john=j
age of andy=a
t<a
if j is not older than t, then he is less than or equal to t so
j ≤ t
but there is an oldest so therefor we assume that j < t
t < a
j < t
subsitute
j<t<a
andy is oldest
tom is second
john is youngest

w - 9 - (-1) > 3
To solve the inequality, we have to get w by itself on one side of the greater than sign, which will give us the answer. So we start by simplifying the left side of the equation. When you subtract a negative, you simply add, so the inequality becomes...
w - 9 + 1 > 3
Now combine like terms
w - 8 > 3
Now add 8 to each side to get w by itself
w > 11
This means that to keep the inequality true, w can be any number greater than 11.

Increase=New number - Original number
Increase=500-850=-350
%increase=Increase/original number X 100
%increase= -350/850 X 100 = -41.18%
Number is negative because it is a percentage decrease.

The result of the fraction is 3.5
we can calculate this like this:
I think that the question is asking between which two natural numbers the result lies, and the result is 3 and 4: it's bigger than 3 and smaller than 4

Hi! Like you wrote down, a supplementary angle is when the two angles equal 180 degrees when added together. You can inference that angle B will be 142 degrees (A+B=180, 38+B=180, B=142). Therefore, it cannot be anything less or more than 142 if you want it to be a supplementary angle. The answer is D, which shows that the answer is 142 and nothing more or less.
