Answer:

x=-3

Step-by-step explanation:

4x-2 = 8x+10

4x-2 (-8x) =8x+10 (-8x)

-4x-2=10

-4x-2 (+2)=10 (+2)

-4x = 12

-4x (divded by -4) = 12 (divided by -4)

x = -3

hope it is correct! and hope i helped

Using the property of exponents, what do you need to multiply 10^-2 by to get 10^-4?
r-ruslan [8.4K]

Answer:

We conclude that using the property of exponents, we need to multiply 10² to get 10⁴. Step-by-step explanation: Let 'x' be the number we need to multiply 10² by to get 10⁴. Therefore, we conclude that using the property of exponents, we need to multiply 10² to get 10⁴.

Plz help Evaluate. 5⋅40
lana [24]

<em><u>Answer: =200</u></em>

Step-by-step explanation:

This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. multiply by the numbers. product it's going to be multiply by the numbers, fractions, factors, and multiples.

5*40=200

40*5=200

200/5=40

200/40=5

Hope this helps!

Thanks!

Have a great day!

Easy % question with adding
Alchen [17]

Answer:

17.00

Step-by-step explanation:

So first you have to add 12.35 to 7.5% which equals 13.27625.

Then you round 13.27625 to the nearest 0.01 or hundredths place and that gives you 13.28.

Then you add 25% to 13.28 and that gives you 16.6 and if you round 16.6 you get 17.00.

I hope I helped! Please give a Rate and Thanks.

Determine the zeroes of 10x2−5=35
OLEGan [10]

Answer:

x = +2, x = -2

Step-by-step explanation:

The equation to solve in this problem is

10x^2-5=35

The first step we do is to subtract 35 on both sides of the equation, so we get:

10x^2-5-35=0\\10x^2-40=0

Now we simplify the equation by dividing both terms by 10:

\frac{10x^2-40}{10}=0\\x^2-4=0

Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:

a^2-b^2=(a+b)(a-b)

Where here,

a = x

b = 2

So we can rewrite the equation as:

x^2-4=0\\(x+2)(x-2)=0

And this equation is zero when either one of the two factors is zero, so the two solutions are:

x+2=0\rightarrow x=-2\\x-2=0 \rightarrow x=+2
