The ages are consecutive even numbers.
The youngest child is (x+3) years old.
Every even number is 2 more than the one before it.
So the three ages are
(x + 3), (x + 5), and (x + 7).
Their sum is x+3 + x+5 + x+7 = 3x + 15
But we're told that their sum is 42, so we can write
3x + 15 = 42 <== the equation
Subtract 15 from each side: 3x = 27
Divide each side by 3 : x = 9 <== the solution
So the three ages are 12, 14, and 16.
The oldest child is 16 years old.
Sqrt (y^4 * y)
Sqrt y*4 = y^2
y^2 sqrt y
Answer:
y=-1/4x-6
Step-by-step explanation:
y intercept is -6 and slope is -1/4
point slope is y-y1=m(x-x1)
you can use and point. i am using (0,-6)
y--6=-1/4(x-0)
y+6=-1/4x
-6 -6
y=-1/4x-6
First, convert the kilograms to grams. One kilogram is 1000 grams. So multiply it by 1000. Then subtract 2305 from 4000. 4000-2305=1695. So 1695 grams were taken out.
