Answer:
GCF = 10
Step-by-step explanation:
Polygon ABCD was dilated by a scale factor of 3/2 to form polygon A'B'C'D'. The scale factor used was 3/2. The length AB is 2 and the length A'B' is 3.
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.
Dilation is the increase or decrease in the size of a figure.

Answer:
105
Step-by-step explanation:
180 - 75 = 105
A.
s=number of strawberry wafers
c=number of chocolate wafers
3s+1c=30
s+c=22
B.
multiply 2nd equation by -1 to do elimination
add to the first equation
3s+1c=30
<u>-s-c=-22 +</u>
2s+0c=8
2s=8
divide by 2
s=4
sub back
s+c=22
4+c=22
c=18
I used elimiation because it seemed right for this one
I can also do subsitution
3s+1c=30
s+c=22
minus s both sides in 2nd equation
c=22-s
sub for c in other equation
3s+22-s=30
2s+22=30
minus 22 both sides
2s=8
divide by 2
s=4
and now
c=22-s
c=22-4
c=18
substiotion because it's easier for some people to see
18 chocolate
4 strawberry
Let's write down what you said:
you double a number
2x
and then add 20,
2x+20
you get 4/7 of the original number.
2x+20=4/7x.
we can get rid of the fractionby multiplying everything by 7:
14x+140=4x
and subtract 4x from both sides:
10x+140=0
move 120 to the other side:
10x=-140
and divide by 10
x=-14
and that's the answer!
