Given equation: 3 + x/2 = 10

1st step subtract 3 from each side:

x/2 = 7

2nd step multiply both sides by 2:

x = 14

Step 1)

3 + x/2 = 10 ..............This is given

Step 2)

x/2 = 7 ....................... Multiplication property of equality.

This step is wrong. This step is called "Subtraction property of equality". This means you have to subtract 3 from both sides

3 + x/2 - 3 = 10 - 3

Simplifying

x/ 2 = 7

Step 3)

x = 14 ....This is called "Multiplication property of equality" because you multiply both sides by 2.

Hope that helps.

Which if the following summation notations represent this series?

kati45 [8]

Answer:

Step-by-step explanation:

Let's look at the sequence:

$3,8,13,\cdots$

The sequence has a common difference. We say it has a common difference because 8-3 has the same value as 13-8.

The common difference is what these differences are equal which is 5.

The sequence is therefore linear or arithmetic (same thing).

So it has form $y=mx+b$ where the slope/common difference is 5.

$y=5x+b$

We need to find the $y-$ intercept $b$ .

The list of points is related to the above sequence:

$(x,y)$

$(1,3)$

$(2,8)$

$(3,13)$

I only need one of these points to find $b$ .

Let's use the first one since it has smallest numbers and I don't wish to use the calculator unless I really have to.

$y=5x+b$ with $(x,y)=(1,3)$ :

$3=5(1)+b$

$3=5+b$

Subtract 5 on both sides:

$3-5=b$

$-2=b$

So the equation for the set of points is:

$y=5x-2$

Now they are using $i$ instead of x[/tex]:

$a_i=5i-2$

Since all summations begin at $i=1$ , then the choices are done to either choice C and choice E.

I need to find how many terms are in the given series. The last number is 33. So what term number is associated with the value 33.

$a_i=5i-2$

$33=5i-2$

Add 2 on both sides:

$35=5i$

Divide both sides by 5:

$\frac{35}{5}=i$

$7=i$

So there are 7 terms and the 7th term is 33.

So the answer is choice E.

Zepler [3.9K]

Answer:

55 gallons, the initial quantity of water in the tank

Step-by-step explanation:

Y is defined as the amount of water in the tank. When X (the number of minutes spent draining) is zero, no water has left the tank. So, the Y-intercept is the initial amount of water in the tank, 55 gallons.
