Answer:3
Step-by-step explanation:
Use equation for slopes: y1- y2/ x1_ x2=
-11-(-5)/-3-(-6)=3
Answer:
$36
Step-by-step explanation:
You have to find the area because the rope is around the edges
3 yards x 6 yards = 18 square yards (area)
Rope is $2 every yard and there are 18 yards so you multiply.
18 yards x $2 = $36

Answer:
0.37
the seven is in the hundredths place
To answer this, set up a system of equations. What we know is that
5x + 2y = 100
And...
x+y=38
x represents the unknown number of 5 points questions
y represents the unknown number of 2 point questions
In my opinion the easiest way to solve this is to use substitution (that is when you find out the value of one variable, either x or y, and substitute that value as the variable).
So,
x+y=38
Subtract x from both sides
y=38-x
Now, plug (38-x) in as y in the other equation.
5x + 2(38-x) = 100
5x + 76-2x= 100
3x+76=100
3x=24
x=8
Now that you know that x=8, you can solve for y.
5x+2y=100
5(8)+2y=100
40+2y=100
2y=60

y=30
X=8
Y=30
There are 8 five point questions on the test and 30 two point questions on the test
The third equation is true
3.95m+8.95b=47.65
good luck
