Step-by-step explanation:
We know that angles in a triangle add up to 180, so:
5x-60+2x+40+3x-80=180
Simplify
10x-100=180
Solve
Subtract 100 from both sides
10x=80
Divide 80 by 10 to find x
x=8

The New York Nicks had a streaky season. They began by winning 4 games in a row, and then they lost 12 games in a row. After those 12 losses, they won every game, finishing with 3 wins for every 2 losses overall. How many games did they win after the first 16 games?
Answers
Using proportions, it is found that they won 14 games after the first 16 games.
This question is solved by proportions, using a rule of three.For each 3 games they won, they lost 2.They lost 12 games, all on the losing streak, and won x games.Hence, the rule of three is:
2 losses - 3 wins
12 losses - x wins
Applying cross multiplication:
[tex]2x = 3(12)[/tex]
[tex]x = \frac{36}{2}[/tex]
[tex]x = 18[/tex]
18 wins, being 18 - 4 = 14 after the first 16 games, hence, they won 14 games after the first 16 games.

m=Slope=2/7b=y-intercept=1/3What’s the gradient and y intercept for c and e and could u explain pls thx
Answers
Step-by-step explanation:
if you are given an equation of a form y=kx+b, k is gradient and b is y-intercept
in c you can write this equation as y=(2x/3)-2,so gradient = 2/3 and y-intercept =-2
in e:6y=2x+3
y=x/3+1/2,gradient = 1/3, y-intercept=1/2
The gradient or Slope in a linear equation is simply the value "a" in this equation : y = ax + b
And the y-intercept is simply the value b.
so for example, what is the slope of y = 5x + 3 ? What is the y-intercept ? Well the gradient (or slope) is 5, and the y-intercept is 3.
So, for a.
y = -1/2x + 8
it's pretty simple : gradient = -1/2
y intercept = 8
Now for c.
[tex]y=\frac{2x-6}{3}[/tex]
[tex]y=\frac{2}{3}x-\frac{6}{3}[/tex]
[tex]y=\frac{2}{3}x-2[/tex]
So the gradient is 2/3 and the y intercept is -2 (and not +2, be careful there is a negative sign :) )
e.
-2x + 6y - 3 = 0
6y = 2x + 3
y = (2/6)*x + (3/6)
y = (1/3)*x + (1/2)
so the gradient is 1/3
and the y-intercept is 1/2
Good luck, your the best :)
Given the following graph what is the slope?
Answers
Answer:
slope = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 1) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
