Answer: He spends more time trading stickers by 15 minutes.
Step-by-step: 1 hour is 60 minutes. So 2 hours is 120 minutes. 120 minutes plus his 20 minutes is 140 minutes. Subtract it from his homework time and he spends 15 more minutes trading stickers.

Which of the following are assumptions needed for simple arithmetic
sergey [27]

Answer:

It depends, see answer below

Step-by-step explanation:

By arithmetic, we refer to the elementary operations between numbers. You can build the integer, rational, real and complex number systems from the natural numbers, so it is enough to obtain arithmetic for natural numbers.

In the axiomatic formulation of natural numbers, you assume that there exists a non empty set N such that multiplication and addition are defined in N with the commutative, associative, distributive and modulus properties. If you take this approach, you need all of the above: Numbers exist, Multiplication, Addition.

A different approach is the following: assume the Peano axioms: The set of natural numbers exists, and it obeys an inductive structure (without going in further details, every natural number has a unique sucessor, and mathematical induction is valid). You can define addition and multiplication inductively, so in this case you only need to assume that numbers exist.

Write an equation of the line passing through each of the following pairs of points.
slavikrds [6]

Answer:

y=\frac{1}{3}+\frac{13}{3}

Step-by-step explanation:

We want to write the equation of a line that passes through (5, 6) and (-1, 4).

First, let's find our slope. We can use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:

m=\frac{4-6}{-1-5}

Subtract:

m=-2/-6

Reduce:

m=1/3

So, our slope is 1/3.

Now, we can use the point-slope form, which is:

y-y_1=m(x-x_1)

For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:

y-6=\frac{1}{3}(x-5)

Distribute:

y-6=\frac{1}{3}x-\frac{5}{3}

Add 6 to both sides:

y=\frac{1}{3}x-\frac{5}{3}+\frac{18}{3}

Add:

y=\frac{1}{3}+\frac{13}{3}

And we're done!
