Answer:
Step-by-step explanation:
To find the LCM of any integer, we take the product of all the <em>highest powers</em> of the factors that appear in the numbers. Factoring our three given expressions gives us the products
Our LCM will be a product of some powers of , , and . The most each factor occurs in the three expressions is once, so our least common multiple is
which can be simplified to

Answer: 0.6kg of flour will be in each batch of scones.
Step-by-step explanation:
Adam has 16.45 kg of flour, and he used 6.4kg to make hot cross buns. This means that the remaining flour would be the total amount of flour that he had initially minus the the amount that he used to make hot cross buns. This is expressed as
16.5 - 6.4 = 10.05 kg
The remaining flour is exactly enough to make 15 batches of scones. This means that 10.05 kg of flour will be enough to make 15 batches of scones.
We want to determine how much flour, in kg, will be in each batch of scones. Let this amount of flour be xkg
If 10.05 kg of flour will be used to make 15 batches of scones. Then,
xkg of flour will be used to make 1 batch if stones
x = 10.05/15
x = 0.67
When we add two equations, it's important to <em>combine like terms</em>
<u>x's with x's </u>
<u>y's with y's </u>
<u>and constants with constants</u>
2x + 5x = 7x
3y + (-y) = 2y
-5 + -12 = -17
Let's put <em>everything together </em>for a final equation
7x + 2y - 17 = 0
or
7x + 2y = 17
If 3x+2+5x-3 then the answer is 8x-1
if 3x-2+5x-3 then the answer is 8x-5
