Answer:
n = 30
Step-by-step explanation:
you want to isolate the n and get it by itself. So you would do the inverse operation. On the other side, you do the same thing.
3r + 2rt = 18
r is the common factor
r(3 + 2t) = 18
r= 18/ 3 + 2t
r= 6 + 9t
Hope this helps!
Answer:
y= 3x-1
Step-by-step explanation:
This is a rhombus and in any rhombus, the diagonals intersects in the middle and they are perpendicular:
So all 4 triangles are right triangles and the sides are the hypotenuses.
1st) Calculate the sides: hypotenuse² = 3² + 4² = 25, and hypotenuse = 5
The area of each right triangle is (4 x 3)/2 = 6 units²
And the area of the 4 right triangles = 4 x 6 = 24 init²
Answer:
the answer would be 12
Step-by-step explanation:
the formula for finding the area of a triangle is b*h/2 so it would be 6*4/2 which is 12
