Answer:
Uma is 11 years 11 months 4 days older
Step-by-step explanation:
Given
Let
x = Uma's age
y = Her brother's
So:
x = 12years 9months 5days
y = 10 months 1 day
Required
How much older is Uma
To do this, we simply calculate the difference (d) in their ages:
This gives:
d = [12 years 9 months 5 days] - [10 months 1 day]
Collect like terms
d = [12 years 9 months - 10 months] + [5 days - 1 day]
d = [11 years 11 months] + 4 days
d = 11 years 11 months 4 days
Answer:
6.08 kg bag unit price: $1.72
7.48 kg bag unit price: $1.86
6.08 kg bag is the better buy
Step-by-step explanation:
To find unit price, divide the price by the amount. 10.47 divided 6.08 equals 1.7203947. Round it to the nearest cent to get 1.72. So, the unit price for the first bag is $1.72. Next divide 13.88/7.48 to get 1.85561. Round it to the nearest cent to get 1.86. So, the unit price for the second bag is $1.86 per kg. The better buy is the cheaper one, so the 6.08 kg bag is a better deal. Hope this helped!
To solve the set of equations given above, we can use the substitution
method where we substitute one equation to the other and solving for one
variable. We do as follows:
<span>0.4x - 0.1y = 2
x = 5 + 0.25y
0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5
<span>Therefore, the correct answer from the choices is option A, (5,0).</span>
