hayden and jamie completed 20 math problems together, jamie completed 2 more than twice the number that hayden completed. Let p
alexdok [17]

Answer:

2p+2+p = 20

Step-by-step explanation:

Let p represent the number of Math problems Hayden completed.

Let 2p+2 represent the number of Math problems Jamie completed.

Next, we have to<u><em> add them together</em></u> so that the total Math problems they completed will be equal to 20.

Let's solve.

  • 2p+2+p = 20
  • 3p+2 = 20
  • 3p = 20-2
  • 3p = 18
  • p = \frac{18}{3}
  • p = 6

Therefore, Hayden completed 6 Math problems.

Next, we have to get how many problems Jamie completed.

Let's solve.

  • 2p+2 = ?
  • 2(6)+2 = ?
  • 12+2 = ?
  • 14

Therefore, Jamie completed 14 Math problems.

Let's check.

  • 2p+2+p = 20
  • 14+6 = 20
  • 20 = 20

It's correct!

Sorry for spamming questions
Salsk061 [2.6K]

Answer:

likely

Step-by-step explanation:

Since most of the spots are greater than 100 (only a few are 100 or free spin or bankrupt)  it is likely that you will land on an amount greater than 100


unlikely  would be if there were only a few spots greater than 100

equally likely would be  about 1/2 the spots  greater than 100 and 1/2 not

impossible would be no spots greater than 100

certain would be all spots greater than 100

I need an answer to this big question
Kisachek [45]

Answer:

RS + ST = RT

23 - 2x     +     9x - 5     =     39

18 + 7x = 39

7x = 39 - 18 = 21

x= 21/7

x = 3

RS = 23 - 2x (given)

RS = 23 - 2(3)

     = 23 - 6

RS = 17
