Let's say x is "number"
14) 2x-5=7
16) 6x-6=12
18) 2x+7=1
20) 8(n-3) or 8(3-n)
19) 9 + x/7=11
21) The product of 2 and the sum of 5 and t is 8
Hope this helped : )
Answer:
Part a)
Part b) The dilation is an enlargement, because the sides of the image are larger than the sides of the original figure.(the scale factor is greater than 1)
Part c) The scale factor is
Step-by-step explanation:
Part a) Write the similarity statement
we know that
If two figures are similar, then the ratio of its corresponding sides is equal
so
substitute the values
----> is true
therefore
the figures are similar
Part b) The dilation is an enlargement, because the sides of the image are larger than the sides of the original figure. (the scale factor is greater than 1)
Part c) we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z------> the scale factor
x-----> corresponding side of the image
y------> corresponding side of the original figure
so
we have
substitute
The scale factor is greater than 1
therefore
Is an enlargement
Answer:
g = 4/5
Step-by-step explanation:
5g - 4 is the equation you can make from this information. After this you put 4 on the other side to get 5g = 4. Next you divide by 5 to get g = 4/5.
