He has ran 4.5 miles at the end of 6 days.
Answer:
C.
Step-by-step explanation:
Here , the given expression is :
ASSOCIATIVE PROPERTY OF ADDITION
For any terms a, b and c
a + (b + c) = (a +b) + c, Here the order of the addition is NOT important.
Now, simplifying the given expression with the above property:
So, the correct option of the all , Option C is the correct option.
Answer:
≈11.7 [ft].
Step-by-step explanation:
1) the ladder and the wall form the right triangle, where the length of the ladder (12 ft) is hypotenuse and the distance between the base of the latter and the base of the wall is the shortest side.
2) the longest side can be calculated according the Pythagoras theorem:
Answer:
80
Step-by-step explanation:
If we assume that Tammy ate 12 of the cupcakes she baked, we can write an equation relating the numbers of cupcakes.
__
<h3>setup</h3>
Let S represent the number of cupcakes Stacey baked. Then S-48 is the number Tammy baked. After Tammy ate 12 of her own cupcakes, the number she had was (S -48) -12 = (S -60). Stacey had 4 times this number:
S = 4(S -60)
<h3>solution</h3>
240 = 3S . . . . . . simplify, add 240-S
80 = S . . . . . . . divide by 3
Stacey had 80 cupcakes.
_____
<em>Additional comment</em>
Tammy had 80-48 = 32. After Tammy ate 12, she had 20. Then Stacey had 80/20 = 4 times as many.
If Tammy ate 12 of Stacey's cupcakes, then Stacey started with 60.
