Answer:
5. 6 baskets
6. 4 inches
Step-by-step explanation:
Both of these questions are about the Lowest Common Multiple <em>(LCM)</em>.
5. The first thing we need to do is make the numbers so that they are split into only the prime multiples.
So,
and
Now that we've done that, the next step is to see which numbers are common in both of them. This will be the LCM of the two numbers.
so the answer
This will have 5 sandwiches and 7 cookies in each basket.
6. Similarly here, we need to do the same thing and split them.
So,
and
.
The two multiples that are common are , so they will be 4 inches.
Answer:
Form an equation:
let x be the price of a shirt
Then, the price of a sweater would be x - 5
So you would have:
4(x - 5) + 3x = 200
simplify
4x - 20 + 3x = 200
7x - 20 = 200
add 20 to both sides
7x = 220
divide both sides by 7
x = about 31.43
That means the cost of the sweater would be 31.43 - 5 = 26.43
Answer:
4 eggs per hen
Step-by-step explanation:
You would need to divide the total number of eggs by the number of hens to see how many each one would produce:
Thus, 64/16 = 4
That gets you 4 eggs per hen!
Well i think that you will have to sub because its talking about how much money are apart from coles so your answer will be 6,738.
