Answer:
37
Step-by-step explanation:
all triangles have a total of 180 degrees
set up equation and solve
180=(2x+4)+(2x-9)+x
180=5x-5
185=5x
37=x
Answer:
4 kg of sugar would contain 
crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
Solve for x. Cross multiply.
Divide both sides by 3
4 kg of sugar would contain crystals.

Answer:
1. (AB) y = 2/3x + -4
Step-by-step explanation:
Formula - y = m(x) + (y-intercept)
m = rise / run
"run = horizontal (left and right)
rise = vertical (up and down)"
the y intercept is always going to be where y is 0 at. (x, y) you will use your x to determine the intercept
So lets use your first question as an example
1. (AB) y = m(x) + (y-int)
y = m(x) + (-4)
the point goes to the right 6 points and goes up 4 points (rise / run)
y = 4/6(x) + (-4)
You can round up the fraction to 2/3
y = 2/3(x) + -4
