Hi!
(l = Lenny
m = Max)
Lenny is 3 times as old as Max.
3m = l
When you subtract Max's age from Lenny's age, you get 24.
L - m = 24
Put in the value of l.
3m - m = 24
There is our equation.
Now solve
2m = 24
2m/2 = 24/2
m = 12
3 * 12 = l
36 = l
The equation is 3m - m = 24
Max is 12 and Lenny is 36.
Hope this helps! :)

Answer:
Concluding that people should take vitamin supplement each day when they don't help.
Step-by-step explanation:
We are given the following in the question:
Hypothesis:
Taking a vitamin supplement each day has significant health benefits and does not have any harmful side effects.
Null hypothesis:
Taking a vitamin supplement each day does not have have significant health benefits.
Alternate hypothesis:
Taking a vitamin supplement each day have have significant health benefits.
Type I error:
- It the error of rejecting the a true null hypothesis.
So error I for this situation would be concluding that people should take vitamin supplement each day when they don't help.
9/100 is less because if we multiply 7/10 by 10 (to get an equivalent fraction with a denominator the same as the other fraction [100]) we get 70/100, which is way more than 9/100.
So, 7/10 is greater than 9/100
Hope this helps!
Answer:
x = 13
Step-by-step explanation:
<em>sqrt (x-4) + 5 = 2</em>
<em>The equation is √(x+4) + 5 = 2</em>
√(x-4) = 2 - 5
√(x-4) = -3
x-4 = (-3)²
x-4 = 9
x = 9 + 4
x = 13
Therefore, the second option x = 13 is correct.
