Answer:
The two numbers are 36 and 9
Step-by-step explanation:
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
We know that: n <44, 48
Let's try some values:
45 - 40 = 4
45- 36 = 9
45- 28 = 17
45- 24 = 21
Pattern: The lesser a natural numer's absolute value, the greater [larger number] it produces. (Bold = "larger numbers")
We recognize something: 36 + 9 = 45 and 36 is exactly 4 times greater than 9.
Answer:
15 Rolls.
Step-by-step explanation:
This problem is one that can be solved simply by dividing.
Take 5, and divide that by 1/3.
However, you can't just do this. The way I did it was by turning 5 into 5/1. Then, Multiply by the reciprocal, which would be 5 x 3, which equals 15.
Answer:
25.5
Step-by-step explanation:
first find angle E.
remember, all angles in a triangle always add up to 180 degrees.
E = 180 - 90 - 20 = 70 degrees
now we use the law of sines.
ED/sin(20) = DC/sin(70) = EC/sin(D)
EC = x
sin(D) = sin(90) = 1
24/sin(70) = x/1 = x
x = 25.5
