Convert 30 days to weeks and days
Zepler [3.9K]

Answer:

4 weeks and 2 days

Step-by-step explanation:

There are 7 days in one week.

To convert 30 days into weeks and days, divide 30 by 7.

The biggest number you can divide it by is 4 [without going over 30]

7 x 4 = 28.

30 - 28 = 2.

So 30 days = 4 weeks and 2 days.

I hope this helps! :)

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.
SCORPION-xisa [38]

The equation of line is:

y = \frac{-3}{2}x+1

Further explanation:

The standard form of equation in point-slope form is:

y = mx+b

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

y = \frac{-3}{2}x+b

To find the value of b, putting the given point (4,-5) in equation

-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1
