Answer:

4-2 is greater.

The problem:

Is 4-2 or 2-4 greater?

Step-by-step explanation:

4-2 is greater because 4-2=2 while 2-4=-2.

4-2 is 2 because if you start at 4 and move left 2 due to the subtraction of 2 then you land on 2 on the number line.

2-4 is -2 because if you start at 2 and move left 4 units due to subtraction of 4 then you have landed at -2 on the number line.

Also 2-4=-4+2=-(4-2). This means 2-4 and 4-2 will have opposite values. 2-4 is a negative number because you are taking a bigger positive number away from a smaller positive number. 4-2 is a positive value because you are taking a positive smaller value away from a bigger positive value. Any positive number are greater than any negative number.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = x - 16

5y = 2x - 56

Step 2: Solve for x

Substitute in y: 5(x - 16) = 2x - 56
Distribute 5: 5x - 80 = 2x - 56
[Subtraction Property of Equality] Subtract 2x on both sides: 3x - 80 = -56
[Addition Property of Equality] Add 80 on both sides: 3x = 24
[Division Property of Equality] Divide 3 on both sides: x = 8

Step 3: Solve for y

Define original equation: y = x - 16
Substitute in x: y = 8 - 16
Subtract: y = -8

Carrie has 40 more nickels than Joan has dimes. They both have the same amount of money. How many coins does each girl have? Wha

LuckyWell [14K]

Answer:

Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.

Step-by-step explanation:

Let be $x$ and $y$ the amounts of nickels and dimes that Carrie and Joan have, as $c$ the total amount of money that both Carrie and Joan have. A nickel is a five cent coin and a dime is a ten cent coin.

The following equations are constructed after a careful reading on statement:

Carrie's amount of money:

$0.05\cdot x = c$ (Eq. 1)

Joan's amount of money:

$0.10\cdot y = c$ (Eq. 2)

Relation between amounts of coins:

$x = y+40$ (Eq. 3)

First we eliminate $c$ by equalizing (Eq. 1) and (Eq. 2):

$0.05\cdot x = 0.10\cdot y$

Then, we reduce the resulting formula by (Eq. 3):

$0.05\cdot (y+40) = 0.10\cdot y$

$y+40 = 2\cdot y$

$y = 40$

And rest of variable are now determined:

$x = 40+40$

$x = 80$

$c = 0.05\cdot (80)$

$c = 4$

Carrie and Joan have 80 nickels and 40 dimes, respectively, and each one has an amount of money of 4 US dollars.

Answer:

B. p+121 is ≤ 345

Step-by-step explanation:

Talula can't go over the amount of 345 because it would go over the limit therefore the less than or equal to sign is needed. It would be p PLUS 121 because it would be a number less than or equal to 345 and p is the variable that is has to be less than or equal to 345.
