Answer:
B
Step-by-step explanation:
Since A represents the number of AFC cars and N represents the number of NFC cards, and that Daryl has 160 total cards, then A+N = 160, the total number of cards. Furthermore, the number of AFC cards Daryl has is 8 more than 3 times the number of NFC cards, so A would be equal to 8 + 3N, or A = 3N + 8. The only system of equations with both of these correct equations is B.
Answer: x=4
Step-by-step explanation:
Subtract 6x from both sides.
5x+3−6x=6x−1−6x
−x+3=−1
Step 2: Subtract 3 from both sides.
−x+3−3=−1−3
−x=−4
Step 3: Divide both sides by -1.
−x/−1 = −4/−1
x=4
I believe the answer would be 3/40
The dilation factor Sophia is using appears to be
(image coordinate)/(original coordinate) = -9/-3 = 15/5 = 3
Then the problem tells us
(pre-image point)×3 = (3, 1)
so we conclude
(pre-image point) = (3, 1)/3 = (1, 1/3)
