Sunny has $4.80 in quarters and dimes. The number of dimes she has is 4 more than 3 times the number of quarters. Which system of equations represents this scenario?
A: 0.01x + 0.25y = 4.80
y = 3x + 4

B: 0.01x + 0.25y = 4.80
x = 3y + 4

C: 0.1 + 025y = 4.80
y = 3x + 4

D: 0.1 + 0.25y = 4.80
x = 3y + 4

Answers

Answer:

Step-by-step explanation:

c

The system of equations representing the scenario given are x = 3y + 4 and 0.25y + 0.1x = 4.8.

What does a System of Linear Equations define?

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations.

Let y be the number of quarters and x be the number of dimes.

Given, number of dimes she has is 4 more than 3 times the number of quarters.

x = 3y + 4

Also, we have that, Sunny has $4.80 in quarters and dimes.

We know,

1 dollar = 4 quarters

⇒ 1 quarter = 1/4 = 0.25 dollar

1 dollar = 10 dimes

⇒ 1 dime = 1/10 = 0.1 dollar

So, we get another equation,

0.25y + 0.1x = 4.8

Hence the system of equations are x = 3y + 4 and 0.25y + 0.1x = 4.8.

32 divided by 4 x (16 x 1/2) - 2

easy answer pls i need to show my work

Answers

Answer:

b

Step-by-step explanation:

The value of the expression 32 divided by 4 x (16 x 1/2) - 2 is 30.

What is Equation?

Equation is  collection of two or more expressions with an Equal sign.

By using PEMDAS rule we solve the expression by following certain operations.

The first step is to solve the expression with in parenthesis.

16 x 1/2 = 8

Now the expression becomes as follow.

32/4 x (8) - 2

Now let us multiply four and eight.

4 x 8 = 32

Therefore, the expression becomes:

32 - 2

Now we use Subtraction

32 - 2 = 30

Therefore, the value of the expression is 30.

Answer:

3 slices each

Step-by-step explanation:

One whole pizza is most commonly 8 slices.

1/8 is one slice

1/4 is two slices

1/2 is four slices

Knowing these values we can use subtraction and division to find the answer.

Since 1/4 is 2, we subtract 2 from 8

8 - 2 = 6

Now since there 2 people splitting it, you divide it by 2 or multiply it by 1/2

Doing so will get you 3 which is the answer
