20
Step-by-step explanation:
y=20+2.8 and got 100%
Answer:
Scale factor = ½
Step-by-step explanation:
The original image is the preimage = ∆ACB
The new image is the image = ∆DFE
The scale of factor of dilation = image/preimage = DF/AC
DF = 6 cm (given)
AC = 12 cm (given)
Plug in the values into the equation to find the scale factor of dilation:
Scale factor = 6/12
Scale factor = ½
Hello,
if 0 is a positive integer
sum=0+1+...+59=(0+59)*60/2=59*30=1770
else
sum=1+2+3+...+60=(1+60)*60/2=61*30=1830
end if
Answer D: 1830
In US, 0 is not positive, in Europe yes!!!
If you add them straight down:
2d-e = 7
d + e = 5
Then the e's cancel out.
You are left with 3d = 12
Then solve for d by dividing each side by 3.
Now you have d =4.
To solve for e go back into one of your original equations and substitute 4 for the d.
You can use either equation, so I'll choose the second one.
4 + e = 5
Now solve for e by subtracting each side by 4.
Now you have e = 1.
So your solutions are d = 4 and e = 1
