12 customers = 9 mins
1 customer = 9 ÷ 12 = 3/4 min
4 customers = 3/4 x 4 = 3 mins
Answer: 3 mins
Answer:
46
Step-by-step explanation:
Let number is x greater than 21 and x less than 71.
Now, according to question,
21+x=71−x
2x=50
x=25
So, required number is 21+x=21+25=46.
Alternatively,
The required number would be the average or mean of 21 and 71.
So, required number =
2
(21+71)
=46.
Answer:
90 red pens
Step-by-step explanation:
we need to find the least common multiple of the numbers 3 , 5 , 6 , 9
6 = 2 × 3
9 = 3²
then
LCM(3,5,6,9) = 2×5×3² = 2×5×9 = 90
The number 90 can be divided into 3 ,5 ,6 ,9 with no remainder
Therefore the pack must have 90 pens or a multiple of 90
For example 180 , 270 ...
Answer:
C. The slope of the function is -2 and the y-intercept is 4.
Explanation:
The y-intercept is the point when x = 0. On the table when x is 0, y is 4.
The slope of the function is -2 because the y value is going down by 2 for each +1 of x.
x │ y
-2 │ 8
0 │ 4
↓ +1 ↓ -2
1 │ 2
↓ +1 ↓ -2
2 │ 0
