Answer:
1047 cards
Step-by-step explanation:
3x349=1047 3x300=900 3x40=120 3x9=27 900+120+27=1047
431.2+826.4d=2910.4
431.2 is only the first day therefore it doesn't need the variable because the variable represents the number of days. 826.4 even says "each remaining day" referring to what the variable represents.
The word greatest in a word problem tells you to do GCF and the word least in a problem means to use the LCM
100 because opposite angles are equal. The angles in the triangle above add up to 80 so the last angle must equal 100. Since angle 1 is directly opposite to that angle, it also equals 100.
