Answer:
6
Step-by-step explanation:
3x plus 12= 8x -18
subtract twelve on both sides:
3x= 8x- 30
minus 8x on both sides:
-5= -30
divide:6
Answer:
Point A and point B have 11 units between
Step-by-step explanation:
If the distance between 0 and 10 is 10 also known as the absolute value, you just add one more unit because it starts at -1
So 10 + 1 = 11 and because we are using 10 is greater than 1 its positive so the answer is 11
Hope this helps :)
This is a common factor problem.
Pencils come in a pack of 12
Erasers come in a pack of 10
First, break the number into their prime factors(the idea is that we will break the number down into its smallest multiples, which are prime numbers):
10 = 2 * 5
12 = 2 * 2 *3
So now we take the unique multiples of each number, and when we multiply them together, we will get the smallest number that both 10 and 12 can be divided into(this is what the problem is asking for)
We have (2*2*3) that comes from 12, and the only unique number that comes from the 10 is (5)
So now, we multiply:
2*2*3*5=60
However, this isn't exactly out answer. Now we have to divide our answer by the number of each this in the pack to know how many packs to buy.
60/12=5 packs of pencils
60/10= 6 packs of erasers

Answer:
6
Step-by-step explanation:
No exact amount of cookies so if its a large batch we'll say there is 45 cookies 45 divided by 1/3 is 15
So 15 divided by 2 1/2 = 6
So your answer is 6.
