Solve for x. Sqrt8 (Sqrt2 - x) = 11

Alexus [3.1K]

Answer: $\frac{-7\sqrt{2} }{4}$

Step-by-step explanation:

So first, let's get rid of the parentheses. We can multiply it out to get $\sqrt{16}-x\sqrt{8} =11$ . We know that the square root of 16 is ±4, so now our equation is ±4 - $x\sqrt{8}$ =11. I'm guessing since the problem only has one solution it's most likely only positive 4, so let's revise our equation to 4 - $x\sqrt{8}$ =11. We can use inverse operations to make the a little easier to solve: -7= $x\sqrt{8}$ . We divide both sides by $\sqrt{8}$ to get $\frac{-7}{\sqrt{8} } =x$ , which we can rationalize (remove the square root from the denominator so that it's a proper answer) by multiplying by $\frac{\sqrt{8} }{\sqrt{8} }$ (which is equal to one so we can use it) which is equal to $\frac{-7\sqrt{8} }{8}$ . Let's finish this by simplifying it. $\sqrt{8} =2\sqrt{2}$ (2x $2^{2}$ ). We can simplify it further by simplifying the 2, making it $\frac{-7\sqrt{2} }{4}$ .

Hope this wasn't too confusing! I'll answer any questions.

One month, Ruby worked 8 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 112 hour

melamori03 [73]

R=8+I
S=4R

R+I+S=112
R+R-8+4R=112
6R=120
R=20

So therefore, Ruby worked 20 hours, Svetlana worked 80 hours, and Isaac worked 12 hours.

Luis and his family flew 51487 miles last summer while on vacation rounded to the nearest thousand how many miles did they fly

ludmilkaskok [199]

In the given mathematical value of 51, 487 to round off this number to the nearest thousand, we can elaborate the number values using the expanded form to clearly see the order position: 1. 50, 000 = ten thousands 2. 1, 000 = thousands 3. 400 = hundreds 4. 80 = tens 5. 7 = ones Now we can observe the numerical value of 51, 487 than 1, 000 is the number in which belongs to the thousands’ position hence since the nearest number is 400 the value will be 51, 000.
