every triangle must equal 180 degrees so add the other two angles and subtract by 180 to get that angle
Hope this helps :)
Answer:
use an online graph to graph it and look at any points lines intersect
Answer:
Solutions are;
x = -8
x = -3.2
Step-by-step explanation:
Here, we want to solve the given equation for x
|(x-4)/(x + 5)| = 4
From what we have, this is an absolute value equation and thus, we are going to have two solutions
These are;
x-4/x+ 5 = 4
x-4 = 4(x + 5)
x-4 = 4x + 20
x-4x = 20 + 4
-3x = 24
x = -24/3
x = -8
secondly;
x-4/x+5 = -4
x-4 = -4(x + 5)
x-4 = -4x - 20
x + 4x = -20 + 4
5x = -16
x = -16/5
x = -3.2
Answer:
use a calculator
Step-by-step explanation:
Answer:
He bought 20 shirts
Step-by-step explanation:
shirts -- x
pants -- 3/4 of x
Therefore,
He bought --- 28(3/4 of x) pants and 40(x) shirts.
So, 28(3/4 of x) + 40(x) = 1220
=> 21x + 40x = 1220
=> 61x = 1220
=> x = 20
He bought 20 shirts and 15 pants.
Thenks and meak me brainliest :))
