My friend needs help on this sorry!

9514 1404 393

Answer:

  $144

Step-by-step explanation:

Multiplication is used to simplify repeated addition. To find the total cost, add up the costs of each of the tickets.

  6 child tickets will cost $10 +10 +10 +10 +10 +10 = 6×$10 = $60

  6 adult tickets will cost $14 +14 +14 +14 +14 +14 = 6×$14 = $84

Then the total cost of all of these tickets will be ...

  $60 +84 = $144 . . . . cost of zoo tickets in all

Amelia and Barrett sold a total of 137 raffle tickets at the football game. Barrett sold 10 fewer than twice as many as Amelia.
gtnhenbr [62]

Answer:

Barett Sold 88 Tickets

Step-by-step explanation:

To Start off we are told that the Total of tickets sold between Amelia (A) and Barrett (B) was 137.

Total = 137

Since Barett Sold 10 less than twice as many tickets as Amelia, we can make the following equation, where Barett is B and Amelia is A.

A + B = 137

A + (2A-10) =137   (Barett equalls 10 less than twice Amelia)

Now we can solve the equation for A

A + (2A-10) =137

3A - 10 = 137  (Combine Like Terms)

3A = 147 (add 10 on both sides)

A = 49 (divide by 3 on both sides)

Now that we have the amount of tickets that Amelia sold we can plug it in for B to find out how many tickets Barett Sold

(2A-10) = B

(2*49) - 10 = B

(2A-10) = B

98 - 10 = B

88 = B

Solve t^4-2t^3+24t^2=0​
AlexFokin [52]

Answer:

t=0, 6, -4

Step-by-step explanation:

first, you can factor out t² of the equation

t²(t²-2t+24)=0, then factor the trinomial

t²(t-6)(t+4)=0, now set each factor equal to zero

t²=0, so t = 0

t-6=0, so t = 6

t+4=0, so t = -4

If you graph it, you can also see the answers.
