Casey has n nickels. megan has 4 times as many nickels as casey has. write an expression for the total number of nickels casey and megan have. then simplify the expression.

n = number of nickels casey has

n is simply a placeholder for a number

4*n = number of nickels Megan has

whatever number Casey has, multiply it by 4 to get Megan's number

We add n and 4n to get 5n. We can think of it as 1n+4n = (1+4)n = 5n

Or we can think of it as 1 nickel + 4 nickels = 5 nickels

The final simplified expression is 5n

lol we need to see what the question is asking about

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
