Savanna and shea both collect stamps. Savannah has 7 more stamps in her collection than shea. Write an expression to repersent the total amount of stamps in both collections

2x+7

Step-by-step explanation: since we don't know the amount of stamps collected by Shea we call x stamps. We were told Shannah has 7 more stamps than Shea who has x. So we assume that Shannah has x+7 stamps. Therefore total stamps collected could be expressed as

Shea's stamps + Shannah's stamps or x + x+7 = 2x+7

Hope it was helpful

2x+7

Step-by-step explanation:

x: number of stamps shea has.

so, savannah has 7 more than shea.

shea has x number of stamps. so if savannah has 7 more than shea, savannah would have x+7. and if you add them up, x+x+7, it totals to 2x+7.

Hoped it helped.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
