Answer:
The triangle could be a right triangle.
Step-by-step explanation:
Right triangles have right angles. (90 degrees). All triangles have 3 angles that add up to 180 degrees. So as long as one of the angles is 90 degrees, it's a right triangle.
Answer:
Move the top side down 2 meters
There are 21 red pens. For every 3 red pens, there is 1 blue pen.
Let's make these into a fraction equation.
21/p=3/1
p is the number of blue pens we have yet to find.
First, cross multiply.
21x1=21
px3=3p
Now, we have an equation of
21÷3p
We set it equal to 1, and we solve it.
21÷3p = 1
(21÷3p)×3p=1×3p
21=3p
21÷3=(3p)÷3
7=p
So, if there are 21 red pens, there are 7 blue pens.
We add these together to find the total number of pens the teacher has.
21+7=28
The teacher has 28 pens total.
Answer:
(17+11)/(-9-5)= 28/-14= -2 the slope
y + 11 = -2(x - 5)
y + 11= -2x + 10
y = -2x - 1 the equation
2/3 x 9 = 6 slices
1/3 x 18 = 6 slices
Hence they give the same number of slices.
