2(x-10)=9 The first step is to get rid of the brackets to do this we multiply 2 with everything inside giving us 2x-20=9. The next step is to isolate the variable and ti do this the first step is to get rid of 20, so you add 20 to both sides giving you 2x=29. So the answer is 2x-20+20=9+20

Express p as the subject of the formula<br>q= p² - r ÷ t

Rudik [331]

Answer:

p = $\sqrt{q +\frac{r}{t} }$

Step-by-step explanation:

q= $p^{2}$ - r÷ t using BODMAS

q = $p^{2}$ - (r/t)

q + r/t = $p^{2}$

p= $\sqrt{q+\frac{r}{t} }$

Answer:

y = -4x+7 is the equation simplified and answer choice A is the right answer.

Step-by-step explanation:

Your equation: y - 6 = -4(x+1)

Your Objective: You need to simplify the original equation and find another equation that is equivalent to the original equation.

Let's focus on the -4(x+1) side first.

This needs to have the distributive property applied.

Take -4 and multiply it by x and 1.

You should have -4x+1

Your equation now:

y - 6 = -4x+1

We want y to be by itself.

So add 6 to both sides.

y = -4x+1+6

Use PEMDAS

y = -4x+7

The first answer choice "A" is correct.
