Elena has 2 fewer hats then fran. Together, they have 14 hats. Which equation represents this situation.
Free_Kalibri [48]
<h2>Greetings!</h2>

Answer:

2x - 2 = 14

Step-by-step explanation:

Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2

So then

x + x - 2 = 14

2x - 2 = 14

You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:

2x = 14 + 2

2x = 16

x = 8

So Fran has 8 hats and Elena has 6 hats.

The model shows the expression 30 + 12.
Slav-nsk [51]

Answer:

4rth   6(5+2)

Step-by-step explanation:

This is because 6 rows of 5 squares means that there is 6 rows with 5 squares each. 6 × 5 = 30. Then there is another set of 6 rows with 2 squares in each, which is 6 × 2 = 12. 30 + 12 = 42. Which is why 6(5+2) = 42. 6(5+2) = 6(5) + 6(2) = 6(7) = 6 × 7 = 6 + 6 + 6 + 6 + 6 + 6 + 6 or 7 + 7 + 7 + 7 + 7 + 7 or 5 + 5 + 5 + 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 = 42.

Alexis has $3.25 in nickels and dimes. The number of dimes is 5 less than twice the number of nickels. Find the number of nickel
jek_recluse [69]

Answer:

15 nickels were there with Alexis

Step-by-step explanation:

Let there be  x nickels

given that

The number of dimes is 5 less than twice the number of nickels.

no of dimes in terms of x = 2*number of nickels - 5 = 2x - 5

we know that

value of 1 nickel = 5 cents

then

value of x nickel = 5*x cents = 5x cents

we know that

value of 1 dime = 10 cents

then

value of 2x-5 dime = 10(2x - 5)  cents = 20x - 50 cents

Total value of x nickel and 2x -5 dimes = 5x + 20x - 50 = 25x - 50

given that

Alexia has total of  $3.25 in nickel and dimes thus  25x - 50 must be equal to $3.25

$1 = 100 cents

$3.25 = 3.25 * 100 cents = 325 cents

Thus,

25x - 50 = 325

25x = 325 + 50 = 375

x = 375/25 = 15

Thus, no of nickels = x = 15  answer
