Answer:
2/3
Step-by-step explanation:
-2x+3=-1+x+2
-2x-x+3=-1+2
-3x+3=1
-3x=1-3
-3x=-2
3x=2
x=2/3
Answer:
Seven less than a number, divided by 5, is -2." Can you turn it into a equation please??
let the number be x
x-7/5= -2
x-7= -10
x= -10+7
x= -3
Step-by-step explanation:
Using trigonometric relations, we will see that:
sin(θ ) = -0.8
<h3>
How to get the sine of the angle?</h3>
For any point (x, y), the angle between the positive x-axis and the ray that connects the origin with the point (x, y) is:
θ = Atan(y/x)
In this case, the point is (3, -4), then the angle is:
θ = Atan(-4/3) = -53.13°
Then the sine of theta is:
sin(θ = -53.13°) = -0.8

The perimeter of a triangle is the sum of all side lengths of the triangle. The numerical expression for the perimeter of Stephanie's triangle is: 
Let the sides of Juan's triangle be x, y and z. So:
The perimeter (J) of Juan's triangle is calculated by adding all sides.
So:
This gives:
From the question, we understand that:
The perimeter (S) of Stephanie's triangle is half that of Juan.
This means that:
Substitute 25 for J
Hence, the numerical expression for the perimeter of Stephanie's triangle is:
