The answer is no because she only got information from one group and she should get the input of other 7th graders
Answer:
The original price of a skateboard is $64
Step-by-step explanation:
Let
x ----> the original price of a skateboard
y ----> the new price of a skateboard
we know that
The linear equation that represent this problem is equal to
y=x-15 ----> equation A
y=49 ---> equation B
substitute equation B in equation A and solve for x
49=x-15
Adds 15 both sides
49+15=x
64=x
Rewrite
x=$64
The angel in the scaled copy that corresponds to angle abc in the polygon pqrs which is a scaled copy of abcd will be angle pqr.
We have,
As we can see the attached figure,
Scale factor : Scale Factor is the ratio of size of new image formed to the size of old image and the image obtained is the scaled copy.
i.e.,
Scale factor = 
So,
There are two Polygons abcd and pqrs,
And,
Polygon pqrs is the scaled copy of Polygon abcd,
So,
That means both polygons are similar,
so,
Their corresponding angles will be same,
So
We can say that angle corresponds to angle abc is angle pqr.
Hence, we can say that the angel in the scaled copy that corresponds to angle abc in the polygon pqrs which is a scaled copy of abcd will be angle pqr.

Answer:
Yes. As long as the sum of two sides is greater than the third side a triangle can be formed.
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
3(y+5)=36
divide both sides by 3
y+5=12
minus 5
y=7
