Answers

Answer 1
Answer: Given:
45,000 seats
5/8 of the seats were bought for the next game.

To get the exact number of seats, we need to multiply the total number of seats by the fraction bought.

45,000 * 5/8 = (45,000 * 5) / 8 = 225,000 / 8 = 28,125 seats

5/8 of the total seats is 28,125 seats which are all unavailable.

8/8 - 5/8 = 8-5/8 = 3/8 is the fraction of the seats available.

45,000 - 28,125 = 16,875 seats available.

45,000 * 3/8 = (45,000 * 3) / 8 = 135,000 / 8 = 16,875

Carissa and Louann both have savings accounts. Carissa has $250 in her account and deposits $80 per month. Louann has $1230 in her account and withdraws $60 per month.After how many months will they have equal amounts of money in their accounts? What amount of money will each have when it is the same amount?

It will take ____ months. Then, they will both have $ ____
in their accounts.

Answers

carissa value after x months=current+amount deposited
louan value after x months=current-amount taken out

carissa depositied=amount per month times x months=80x
louan take out=amount per month tiems x months=60x

when wil amount be equal
se equal

cariss=lousa
250+80x=1230-60x
add 60x both sides
250+140x=1230
minus 250 both sides
140x=980
divide both sides by 140
x=7

find how much that is
250+80(7)=250+560=810

Answer:

11= EC

Step-by-step explanation:

EC = 10 + 2 x + 19

= x + 20

So 2 x + 29 - x - 20 = 0

so x + 9 = 0

x = -9.

EC = x + 20 = -9+20 = 11.

Answer:

EC = 11 units

Step-by-step explanation:

  • first we find the value of x

10 + 2x + 19 = x + 20

2x - x = 20 - 10 - 19

x = -9

--------------------------------

check

10 + 2(-9) + 19 = -9 + 20

10 - 18 + 19 = -9 + 20

11 = 11

same value the answer is good

  • Now we find EC

EC = 10 + 2x + 19

EC = 10 + 2(-9) + 19             (remember PEMDAS)

EC = 10 - 18 + 19

EC = 11 units

Elia is training for her first marathon. she currently runs 10 mi. per week, and wants to increase her mileage by 2 mi. every week. if elia keeps to her training schedule write a formula to define the number of miles she runs each week. ( 1 point)

Answers

Answer: Required expression is given by

y=8+2x

Step-by-step explanation:

Since we have given that

Number of miles per week Elia is training for her first marathon = 10 miles

According to question, we have given that she wants to increase her mileage by 2 miles every week.

so, Equation becomes

10,12,14,16..........

Let the number of weeks be x

Since it forms an Arithmetic sequence,

As we know the formula for nth term :

a_x=10+(x-1)2\n\ny=10+2x-2\n\ny=8+2x

So, our required expression will be

y=8+2x

Answer:

y=2x+8

Step-by-step explanation:

Given is the number of miles per week Elia is training = 10 miles

And she wants to increase her mileage by 2 miles every week. Means the next week she will run 12 miles, next week she will run 14 miles and so on.

The series goes like this 10,12,14 and so on. This forms an arithmetic sequence.

Let the number of weeks be represented by x

The formula for nth term :

a = d (n - 1) + c, where d is the common difference between consecutive terms, and c = a1.

So, equation becomes a=10+(x-1)2

y=10+2x-2

y=8+2x or y=2x+8

Hence, the formula is : y=2x+8
