Help!!!!!!!!!!!<br> Solve for x<br> x+11+8x=29<br> Explain how you got the answer please!
dolphi86 [110]
X + 11 + 8x = 29. We need to solve for x.
First, on the left side, you have "x" and "8x": You can always add 2 numbers with the same variable, so you have 1 number: x + 8x = 1x + 8x = (1+8)x = 9x

So we get:
9x + 11 = 29

Now subtract 11 from both sides (You can't do any operation if you don't do it both sides), so you can get the variable alone on the left side, and the numbers on the right side:
9x + 11 = 29
9x + 11 - 11 = 29 - 11
9x = 18

Now divide both sides by 9, so you can transform the coefficient of x to one, and have the numeric value of x on the right side:
9x = 18
(9x)/9 = 18/9
x = 2

So x+11+8x = 29 for x = 2.

You can recheck your answer (very important):
x + 11 + 8x = 2 + 11 + 8*2 = 2 + 11 + 16 = 13 + 16 = 29
The answer has been approved.

Hope this Helps! :)

Which transformations of the graph of 1x) = -4*x result in the graph of f(x) = 4x+3?
KATRIN_1 [288]

First we need to take the - signal

So the difference between the graphs y = -4x and y = 4x is that they are mirrored by the y-axis

Now we have the graph y = 4x and want the graph y = 4x + 3

We just need to move the graph y = 4x 3 units to the left

So the transformations we need is to move it 3 units to the left and to mirror it by the y-axis

How are the values of the eights in 880 related
Neko [114]
<span>How the value of 8 in 880 related
=> 880 = 8 hundreds 8 tens
=> This given number is a whole numbers, thus the value of 8 in the hundreds place is ten times larger than the 8 In the tens place. How?
Try multiplying 8 tens by 10
=> 8 tens = 80
=> 80 x 10
=> 800
When 80 is multiplied by ten the answer is 800 and when 800 is divided by 10 the answer is 80.
That concludes that there’s 10 times difference between the two 8s in the given number.</span><span>
