7(4-x) = -14

Use Distributive Property"

28-7x = -14

Subtract 28 from each side:

-7x = --42

Divide both sides by -7:

x = 6

1.) You have to get rid of everything but x. So let's get rid of the four by multiplying. 7 (4-x) = -14 is equivalent to 28 -7x = -14.

2.) Now, let's get rid of 28, by subtracting it from both sides. (28-28) -7x = -14 -28.
-7x = -42

3.) All that's left to do is to isolate the variable, x, by getting rid of -7. To do so, divide both sides by -7. -7 ÷ -7 = -42 ÷ -7
x= 6.

4.) X=6

Hope this helped. :)

100 POINTS!!! can someone please explain how to do this?
ivolga24 [154]

Answer:

x =pi/2,3pi/2

Step-by-step explanation:

sin²(x) - cos²(x) - sin²(x) = 0

Simplify

sin²(x)  - sin²(x) = 0

Leaving us with

- cos²(x)  = 0

Divide each side by -1

- cos²(x/-1  = 0/-1

 cos²(x)  = 0

Take the square root of each side

sqrt( cos²(x))  = sqrt(0)

 cos(x)  = 0

Taking the inverse cos of each side

cos^-1(cos(x))  = cos^-1(0)

x = pi/2     x = 3pi/2

Murljashka [212]

Given:

Oven's temperature rose 3 degrees in \dfrac{1}{6} of a minute.

To find:

How much will the oven heat up in 1 minute at that rate?

Solution:

According to the question,

Oven's temperature rose in \dfrac{1}{6} of a minute =3 \text{ degrees}

Oven's temperature rose in 1 minute =6\times 3 \text{ degrees}

                                                             =18 \text{ degrees}

Therefore, the oven's will heat up 18 degrees in 1 minute.
