Given
-11.2+4(2.1+q) = -0.8

Take -11.2 to the right hand side of the equation (sign will change when we move it to the other side)
∴ 4(2.1+q) = -0.8 + 11.2

Simply both sides
∴ 4*2.1 + 4*q = 11.2-0.8
∴ 8.4 + 4q = 10.4

Take 8.4 to the right hand side
∴ 4q = 10.4 - 8.4
∴ 4q = 2
∴ q = 2/4
∴ q = 1/2 = 0.5

$-11.2+4(2.1+q) = -0.8\\
-11.2+8.4+4q=-0.8\\
4q=2\\
q=\frac{2}{4}=\frac{1}{2}$

Answer:

$4x^{6}2y^{-2}$

Step-by-step explanation:

We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)

But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.

We will start with the x in the numerator.

3*4 = 12

Now for the y in the numerator.

4*4 = 16

Our new numerator is $4(2x^{12}y^{16})$

We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.

We will start with x's coefficient.

2*4 = 8

Now for y's coefficient.

1**4 = 4

*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.

Our final simplified numerator is $8x^{12}4y^{16}$ .

Repeat with the denominator.

Try it yourself!

Make sure that when you finish, you finish the fraction.

After completing the denominator, your completed fraction should be:

$\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}$

Now we can use the SEi-F to complete the problem.

Start with x.

8x - 4x = 4x

12 - 6 = 6

The first term is $4x^{6}$ .

Now for y.

4y - 2y = 2y

16 - 18 = -2

The second term is $2y^{-2}$

The complete, simplified equation is $4x^{6}2y^{-2}$ .

I could be wrong on the answer, but the work should be correct.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

6's - 10 equal 2 + 3 S Plus s

Lorico [155]

6s - 10 = 2 + 3s + s

6s - 10 = 2 + 4s
6s - 4s = 2 + 10
2s = 12

s = 6

Santos flipped a coin 300 times. The coin landed heads up 175 times. Find the ration of head to total number of coin flips. Expr

xxMikexx [17]

Hi there!

Let's solve this problem step by step!
If a coin is flipped 300 times and it landed 175 times in heads, we can find out that it landed on coins for 125 times, since 300 - 175 = 125.

Therefore the ratio heads to coins is
175 : 125

Now we can search for the simplest form of this ratio. We can divide both sides by 25 to find our answer (we do this because we must divide by the largest possible integer). When we divide both sides by 25, we find the following ratio
7 : 5

Hence, the answer is D. 7 : 5
~ Hope this helps you!
