Whats 345*28923+808(2829)=

RoseWind [281]

Hi there!

345*28923+808(2829)

The first step put the problem into 2 parts, the first part is 345*28923

The second part is 808(2829)

The parentheses means to multiply that number that it touches.

Add the final 2 answers.

345*28923 = 9,978,435

808(2829) = 2,285,832

Now, add the answers.

9,978,435 + 2,285,832 = 12,264,267

Hope this helped!~

Y=6x – 11 -2x – 3y =-7

Eva8 [605]

Answer:

x=2 and y=1

Step-by-step explanation:

1). Plug the y value into the second equation. It will look like the following afte you plug in what y equals:

-2x-3(6x-11)=-7

2). Then, you distribute the "-3" to all the terms inside the parenthesis.

-2x-18x+33=7

3). Then, you subtract the positive 33 from both sides to try to get the x alone on one side.

-2x-18x=-40

4.) Then, you combine all of the terms containing an x.

-20x=-40

5). Finally, you divide both sides by -20 and the outcome is x=2.

6). Hold up...we ain't done yet..

7). Next, you have to plug the x back into the either equation to get the outcome of what y will be, but for this purpose I will plug it back into the first equation.

y=6(2)-11

8). I will then distribute the 6 into the all the terms in the parenthesis and then it will look like this.

y= 12-11

9). Do the math...and the answer is y=1.

Help PLEASE!!!! I don’t understand this

ra1l [238]

In the first problem you are given a formula (y = 3x), along with a table.
From the data in the table, find the slope of the linear equation that relates x and y in that data.

Then compare the two slopes. Which is the greater? the smaller?

Find the number of terms, n, in the arithmetic series whose first term is 13, the common difference is 7, and the sum is 2613.

siniylev [52]

Answer:

Step-by-step explanation:

Recall that the sum of an arithmetic series is given by:

$\displaystyle S = \frac{n}{2}\left(a + x_n\right)$

Where n is the number of terms, a is the first term, and x_n is the last term.

We know that the initial term a is 13, the common difference is 7, and the total sum is 2613. Since we want to find the number of terms, we want to find n.

First, find the last term. Recall that the direct formula for an arithmetic sequence is given by:

$x_n=a+d(n-1)$
