Answer: n=p/2-m

Step-by-step explanation:

m=p/2-n (1)

Add n to both sides of the equation (1)

m+n=p/2-n+n => m+n=p/2 (2)

Subtract m from both sides of the equation (2)

m-m+n=p/2-m => n=p/2-m

Find the measure of two complementary angles, a and b, if m a = 7x + 4 and m b =4x + 9

VashaNatasha [74]

Complentary angles add to 90 degrees
a and b are complentary
a+b=90

a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7

m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37

angle a measures 53 degrees
angle b measures 37 degrees

2(3/5x+3). How would I get that answer

Airida [17]

Answer: $\frac{6}{5}$ x + 6

Step-by-step explanation:

We will use the order of operations, also known as PEMDAS. See attached. Please note that we cannot do what is in the parentheses first because we have a variable, so we will distribute the 2 into it. Since this is an expression, I do not believe we can fully solve for x, but can only simplify.

Given:

2(3/5x+3)

Distribute:

2 * (3/5x) + (2 * 3)

6/5x + 6

Answer:

$\frac{6}{5}$ x + 6
