Answer:
Step-by-step explanation:
Lupita brought seven pounds of pretzels at a local wholesaler for 16.80. This means that the rate at which she bought one pound of pretzel at the local wholesaler would be
16.80 / 7 = $2.4 per pounds of pretzels
Her friend, Charles about 5 pounds of pretzels at the supermarket 12.75. This means that the rate at which Charles bought one pound of pretzel at the supermarket would be
12.75 / 5 = $2.55 per pounds of pretzels
Charles's reasoning is wrong because the rate at which he bought one pound of pretzel is higher than that of Lupita's
I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12
Answer:
y=9
Step-by-step explanation:
replace the x only with -3
you get y = - -3 + 6
Two negatives= positive
+3+6=9
y=9
Answer:
x=4
Step-by-step explanation:
;)
Step-by-step explanation:
We will prove by mathematical induction that, for every natural 
,
We will prove our base case, when n=4, to be true.
Base case:
Inductive hypothesis:
Given a natural ,
Now, we will assume the induction hypothesis and then use this assumption, involving n, to prove the statement for n + 1.
Inductive step:
With this we have proved our statement to be true for n+1.
In conlusion, for every natural 
.
