First, convert 1 kg to g.
1 kg = 1000 g
So 1000 g = 1.28
Set up a proportion:
1000/1.28 = 250/x
Cross multiply:
1000x = 320
Divide 1000 to both sides:
x = 0.32
So 250g costs £0.32
Answer:
With that amount of yougurt she can make 54 smoothies.
Step-by-step explanation:
In order to calculate how many smoothies Nicole can make with the amount of yogurt she has we need to take the total amount of yogurt and divide it by the amount used in each smoothie. So we have:
total yorgut = 81/2 cups
each smoothie = 3/4 cup
number of smoothies = (81/2)/(3/4) = (81/2)*(4/3)
number of smoothies = 27*2 = 54 smoothies
With that amount of yougurt she can make 54 smoothies.
6x+3y=12. so... 6x=12-3y.
6x-5y=60, so... 6x=60+5y
As 6x=6x
12-3y=60+5y
12-60=8y
8y=-48
So y=-48/8=-6
When y=-6,
6x-5(-6)=60
6x+30=60
6x=30
Therefore x=5.
So x=5 and y=-6.
That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.
