Slope Formula: 
Simply plug in 2 coordinates into the slope formula to find slope <em>m</em>:
X is how much it costs for one hour, so when you multiply it by 3 1/2, you get the amount of money charged for 3 and a half hours.
Answer:
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
Step-by-step explanation:
Martin has 2 5/8 pounds of ground beef.
2 5/8 = 21/8 pounds = 2.625 pounds
Because 21 is divisible by 3 and 7, we can arrange the ground beef in two configurations
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
<span>Direct proof. A direct proof is a way of establishing the truth or falsehood of a given mathematical statement by a combination of established facts, usually axioms, lemmas and theorems. It assumes the hypothesis of a conjecture is true and then uses a series of logical deductions to prove that the conclusion as well.</span>
1/2 ÷10=1/20 because you multiply the bottoms
3÷1/6= 18 because it is the same as 3×6
