How does your answer help you solve a division equation such as x/7 =2 ?

Answers

dunno

I can solve it though
x/7=2
multiply both sides by 7
x/7 times 7/1=2 times 7
7x/7 =14
7/7 times x/1=14
1 times x=14
x=14


answer is 14

hmm, maybe multiply bottom number by the one on the other side of the equal sign
You plug in your answer for x and solve it to see if it = 2. So x=14. You plug it back into the equation. 14/7=2
2=2
Your answer is correct.

-4=x-15 show how you got the answerA.) -4/15
B.) -19
C.) -60
D.) 11

Answer: D)11

Step-by-step explanation:

-4=x-15

get x to be alone so add 15

Answer:

I think we're probably talking about a right triangle. So just find the adjacent side and the hypotenuse.

Step-by-step explanation:

Once we are considering x \in \mathbb{R}, the range of  \text{cos}(x) is [1, -1]. Therefore, $(42)/(41) $ is not true.

In this exercise, we may have

$\text{cos}(x)=(x)/(r) =(x)/(√(x^2 +y^2) ) $

Considering the trigonometric functions beyond the unit circle.

Or considering the definition in the right triangle:

$\text{cos}(x)=\frac{\text{adjacent}}{\text{hypotenuse}} $

Simplify -6 (x - 3) - 4 (y +5) + ( -5) (7 -2b)
