Answer:
Total amount of water = 5,200,000
Step-by-step explanation:
Given:
water produced = 50,000 quarts of water per week
Production drop = 5% = 0.05 per year
Number of week in year = 52 week
Find:
Total amount of water
Computation:
Sum = a / r
a = 50,000 x 52
a = 2,600,000
Sum = a / [1-r]
Sum = 2,600,000 / 5%
Sum = 2,600,000 / 0.05
Total amount of water = 5,200,000
$12.79+$3.39=$16.18
$16.18+7.75% tax is $1.253
The first one is x=4.16z
The second one is x=1.16z
The third one is x=6z
Answer:
Ok But What Is The Q:
Step-by-step explanation:
The two equations given are:
3y + 2z = 12
y - z = 9
Now let us take the second equation first and find the value of y in relation to z
y = 9 + z
Now we will put the value of y found from the second equation in the first equation.
3y + 2z = 12
3(9 + z) + 2z = 12
27 + 3z + 2z = 12
5z = 12 - 27
5z = -15
z = -(15/5)
= -3
Now again we will put the value of z in the second equation for finding the value of y
y = 9 + z
= 9 - 3
= 6
So we find the value of "y" is 6 and that of "z" is -3
