Answer:
$3.74
Step-by-step explanation:
5 pounds is 9.35 means 1 pound is 1.87 dollars
2 pounds is 3.74 dollars
There are 9,000 markers in total
750 x 12 = 9,000
Answer: 18
Step-by-step explanation:
The least common denominator of
and
is going to be a multiple of 9 and 6. Let us list them out:
9: 9, <u>18</u>, 27, 36, 45, 54, 63, 72, 81, 90
6: 6, 12, <u>18</u>, 24, 30, 36, 42, 28, 54, 60
You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).
This is system of equations and as such there are two methods of solving: elimination and substitution. Luckily Y is already isolated here, so in this case we just have to put in the value of y into 3x + 2y = 6
To do this we simply do:
3x + 2(-3/2+5) = 6
Distribute the 2 into the brackets
3x + -6/2 + 5 = 6
Move the 5 over and simplify the fraction
3x + (-3) = 1
Move the three over.
3x = 4
Isolate x
x=4/3
Answer: 7 of them remain.
Step-by-step explanation: 10, 13, 16, 17, and 20 were the numbers given that are smaller than 22. 11, 12, 14, 15 18, 19, and 21 remain.
