160 i believe. to find the area of a triangle act like its a square and divide in half. for squares multiply base by height.
take the area of each shape and add it up
4 2/5 = 22/5
3 1/7 = 22/7
22/5 x 7/22 = 154/110 = 7/5
The answer is 1 2/5
<span>4*(5+3)-(8/4)+3*4
4(8) - (2) + 3 x 4
32 - 2 + 12
30 + 12
42
The answer is 42, I believe.</span>
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.
