Write an expression involving integers for each statement a) moving 4 steps left, then moving 9 steps right b) on 3 separate occ
Nostrana [21]

Answer:

(a)-4+9

(b)-2 \times 3

Step-by-step explanation:

<u>Part A</u>

Moving 4 steps left, then moving 9 steps right

When you move left, we indicate with a negative sign while a move right is indicated with a positive sign.

Moving 4 steps left = -4

Moving 9 steps right = +9

Therefore, an expression for the statement is:-4+9

<u>Part B</u>

When you lose or owe in word problems, it is usually indicated using a negative sign.

Therefore, the statement Shari lost 2 pencils can be represented with the integer: -2

Since Shari lost 2 pencils on 3 occasions, we simply have:

-2 \times 3

A pile of 55 coins consisting of nickels and dimes is worth $3.90 . Find the number of each.
Colt1911 [192]

Answer:

23 dimes, 32 nickels

Step-by-step explanation:

Let <em>n</em> equal the number of nickels and <em>d</em> be the number of dimes. We can use the information given to create a system of equations, as follows:

The total number of coins (the number of nickels plus the number of dimes) is 55, giving us the equation n + d = 55.

The total amount is $3.90. Since each nickel is worth $0.05 and each dime is worth $0.10, we get the equation 0.05n + 0.10d = 3.90.

Multiplying the second equation by 20, we get n + 2d = 78. We can subtract the first equation to get d = 23. Substituting this into the first equation, we get that n = 32.

Therefore, there are 23 dimes and 32 nickels.
