How many 3-digit numbers with all even digits.

1 answer:

6 0

For the first digit, you have 4 choices (2, 4, 6, 8); for the second and third digits, you have 5 choices (2, 4, 6, 8 and 0). So the total number of positive qualifying numbers is 4*5*5 = 100

Given the system of inequalities:

Margaret [11]

Answer:
First inequality: y > $\frac{4}{5} x - \frac{1}{5}$
Second inequality: y < 3 + x

Explanation:
The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept

This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.

First given inequality:
4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y > $\frac{4}{5} x - \frac{1}{5}$
comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5

Second given inequality:
y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3

Hope this helps :)

2.16= with the repeating decimal being 6

Goshia [24]

Since the .16 is in the hundredths place, the fraction is 2 16/100, or 216/100

But if you need to simplify it it's 2 4/25, or 54/25
