Answer:

Step-by-step explanation:

the angles of a triangle all add up to 180

thus, we can combine every term given and set them equal to 180 and solve for x

$9x + 72 = 180 \\ 180 - 72 = 108 \\ 108 \div 9 = 12$

steposvetlana [31]

Answer:

Expand $-3(9-x): -27 + 3x$

Step-by-step explanation:

$-3(9-x)$

Apply the distributive law: $a(b-c)=ab-ac$

$a = -3, b=9, c=x$

$=-3*9-(-3)x$

Apply minus - plus rules:

$-(-a)=a$

$= -3*9+3x$

Multiply the numbers: $3 * 9 = 27$

$=-27+3x$

Hope this helps! If so, may I get Brainliest and a Thanks?

yan [13]

Answer:

Add 22/63

Step-by-step explanation:

3/7 + n = 7/9

<u>Step 1: Subtract 3/7 from both sides</u>

3/7 + n - 3/7 = 7/9 - 3/7

n = 49/63 - 27/63

n = 22/63

Answer: Add 22/63
