Answer:

4, and -9

Step-by-step explanation:

Well, to solve this problem, lets first list all the factors of -36.

-36 = 1*(-36)

-36 = 2 * (-18)

-36 = 3 * (-12)

-36 = 4 * (-9)

-36 = 6 * (-6)

-36 = 12 * (-3)

-36 = 18 * (-2)

-36 = (-36) * 1.

So, we can see that 4 + (-9) = -5.

Answer:

$\frac{6}{5}$ of an hour = 1 1/5 hour = 72 minutes

Step-by-step explanation:

$\frac{1}{3} h + \frac{1}{2}h = 1\\\\\frac{2}{6} h + \frac{3}{6}h = 1\\\\\\\frac{5 }{6} h =1\\\\h=\frac{6}{5}$

John's age is 4 more than 3 time Mike's age. If their sum is 20, how old are Mike and John?

natima [27]

Let me help you with this :)

John = x
Mike = y

x = 4 + 3y (4 more than 3 times)

x + y = 20 (we put the x above into this equation)

4 + 3y + y = 20
4y = 16 (we transfers the 4 on the left side to the right side and subtract it from the 20)
y = 4 (the answer is 4)

we use this for the equation:

x = 4 +3*4
x = 16

John is 16 years old and Mike is 4 years old :)

Write the slope intercept form of the equation of the line through the given point

ozzi

Answer:

y = $-\frac{3}{4}$ x

Step-by-step explanation:

slope-intercept form: y = mx + b

Given: slope(m) = $-\frac{3}{4}$ , point (4, -3)

We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:

-3 = $-\frac{3}{4}$ (4) + b

Solve for b:

-3 = $-\frac{3}{4}$ (4) + b

-3 = -3 + b

0 = b

The value of b is zero. We can now write the equation:

y = $-\frac{3}{4}$ x + 0

y = $-\frac{3}{4}$ x

The equation written in slope-intercept form is: y = $-\frac{3}{4}$ x

Explain how to compare two lengths that are measured in different sized units

nalin [4]

There are conversion tables everywhere that assist you in changing a different unit into another. Depending on what it is, you can also compare weight into water, cm into m and backwards.
