Answer:
Step-by-step explanation:
Given : The cost of one dozen of eggs = $0.59
The quantity of eggs Mr. Grocer has = 421 dozens
Therefore, to find the total cost of the eggs we need to multiply the cost of 1 dozen of eggs to the quantity of eggs.
Hence, the cost of total eggs Mr. Grocer has =
Thus, the cost of total eggs Mr. Grocer has =
Answer:
x = 2
Step-by-step explanation:
First, let's write out our equation:
I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:
Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:
And then I'll add like terms:
Now, all we have to do is divide both sides by 5:
And there's our answer. Hopefully that's helpful! :)
Since we know that a number is divisible by 3 if the sum of all digits is divisible by 3.
Let us check which digits will make 371? divisible by 3.
11 is not divisible by 3.
Now let us check other digits as well.
12 is divisible by 3.
15 is also divisible by 3.
18 is divisible by 3 as well.
Therefore, 1, 4 and 7 in tenth place will make our number divisible by 3 and our numbers will be 3711, 3714 and 3717.
