Mathematics
1 answer:
Rzqust [24]3 years ago
6 0

Step-by-step explanation:

Get n by itself. It doesn't matter how you do it, you'll get the same answer whether you subtract m or add n to the other side. You just need to have a positive n by itself on one side of the equation.

a=m-n\\n+a=m\\n=m-a

Answer:

B. n=m-a

Perimeter of a square is (12x-2y). What is the algebraic expression for the length of the side of the square?
sashaice [31]

Answer:

s = 3x - (1/2)y

Step-by-step explanation:

The perimeter of a square is 4s, where s is the side length.  Here,

In the diagram, lines AB , CD, and EF intersect at G
Ghella [55]

Answer:

D. 70°

Step-by-step explanation:

Given:

m<DGB = 35°

m<CGF = 75°

Required:

m<AGE

SOLUTION:

m<EGD = m<CGF (vertical angles are congruent)

m<EGD = 75°

m<AGE + m<EGD + m<DGB = 180° (angles on a straight line)

m<AGE + 75° + 35° = 180° (substitution)

m<AGE + 110° = 180°

Subtract 110 from each side of the equation

m<AGE = 180° - 110°

m<AGE = 70°
