Answer:
(C) 18
Step-by-step explanation:
We can create a systems of equations. Assuming 
is Michelle's age, 
is Joan's age, and 
is Ryan's age, the equations are:
We can use substitution, since we know the "values" of m and j.
So we know that Joan is 18 years old.
Hope this helped!
Answer:
Step-by-step explanation:
Since, angle 1 is an exterior angle of ΔABE,
m∠1 > m∠3 and m∠4
Since, angle 1 is an exterior angle of ΔABD,
m∠1 > m∠5
Since, angle 1 is an exterior angle of ΔABC,
m∠1 > m∠7 and m∠8
Therefore, ∠1 is greater than ∠3, ∠5, ∠7 and ∠8.
<u>No solution</u>: because the absolute value is positive and can't equal a negative
|x| = -1
<u>One solution: </u>because zero only has one sign
|x| = 0 ⇒ x = 0
<u>Two solutions:</u> absolute value is positive whether x is positive or negative.
|x| = 2 ⇒ x = 2 or x = -2
This is a funny one. teachers do this to try to confuse you with the numbers. first you need to find out what is important in the question.
2 mammoths, 7 hours, 11 kilometers.
&
5 mammoths, ? hours, 22kilometers.
the amount of mammoths do not matter, because each walk the same speed.
so you only need to look at this.
7 hours to go 11 kilometers
&
? hours to go 22 kilometers
fast answer is. it's twice the distance so it will take twice as long. 14 hours.
solve answer.
7×60min = 420min
420min ÷ 11 kilometers = 38.18181818min per 1 kilometer.
38.18181818 • 22 = 839.999999min round up 840.
840min ÷ 60min = 14 hours
Answer:
Mixed number: 
Improper fraction: 
Step-by-step explanation:
A mixed number is a number that contains an integer part and a fraction part.
An improper fraction is a fraction where the numerator is greater than the denominator.
can be written as in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.
The mixed number is since 
goes into 
three full times and the remainder is 
.
∴The mixed number is and the improper fraction is .
