Answer: x =-1
Step-by-step explanation:
4x-18=7x-15
4x-7x=-15+18
-3x=3 , x=-1 since 3/-3=x
Answer
The height of the trapezoid = 3 cm
Explanation
The area of a trapezoid is given as
Area = ½ (a + b) h
where
a and b = base lengths of the trapezoid
a = 9 cm
b = 7 cm
h = height of the trapezoid = ?
Area = 24 cm²
Area = ½ (a + b) h
24 = ½ (9 + 7) h
24 = ½ (16) h
24 = 8h
8h = 24
Divide both sides by 8
(8h/8) = (24/8)
h = 3 cm
Hope this Helps!!!
Answer:
A
Step-by-step explanation:
This is how I write
y=kx+m
but I have seen some write it like this:
y=mx+b
Well both of them are the same thing, I'll use the first one because I'm more comfortable with it.
y=kx+m
To find out what k
So you first need to choose two points.
I'll go for (0,-5) and (2,0)
Now you could insert k into the equation and it will look like this.
To find out what m is just pick one point and insert it into the equation. So if I pick (0,-5). 0=X therefore it should be replaced by x and -5=y therefore it should also be replaced by y.
m=-5
Try it with another point to see if you get the same answer. this time I'll pick (-6,10)
m= -5
The equation will be y=-5/2x-5)
∠1 and ∠2 are supplementary angles. So ∠1 is 45 degrees. ∠7 is also 45 degrees because ∠1 and ∠7 are congruent
Answer:
18057
Step-by-step explanation:
uh just 200 x 10 = 200 add that to the 6 to make 18057$ which is the price of the second van.
