Step-by-step explanation:
Answer:
c).3
Step-by-step explanation:
let the number be x
5x-3=x+9
collect like terms
5x-x=9+3
4x= 12
divide both sides by 4
x=3
the number is 3
Answer:
x= 66
Step-by-step explanation:
if you set up the equation mathematically, it would be x+0.5x=99, because 50% is essentially just 0.5.
so, now that you have the equation, you have to add like terms, so it would be 1x+0.5x=99, and 1+0.5 is 1.5, so youre left with the equation 1.5x=99.
from there, you solve for x by dividing each side by 1.5:
1.5x=99
/1.5 /1.5
x=66
im sorry if this didnt make much sense, but i hope this helped!! :D
Answer:
the scale factor k is between 0 and 1
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
A dilation with the larger image than initial figure is called an enlargement.
A dilation that the smaller image than initial figure is called a reduction.
- If the scale factor k is greater than 1, the image is an enlargement
- If the scale factor k is between 0 and 1, the image is a reduction
- If the scale factor k = 1, the figure and the image are congruent
Thus, if the image is smaller than the original figure, then the scale factor k is between 0 and 1.
