First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number). 

For 3, I would count 3 numbers to the right from zero. 

For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25. 

For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4. 

For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.

Larry paid $4.16 for 4 tomatoes. At this same rate, how much would 7 tomatoes cost?
Anna71 [15]
The question is asking us to find how much seven tomatoes would cost. Well, to get our answer, we must first find the cost of one tomato.  We are given the information that paying $4.16 for 4 tomatoes. All we have to do now is divide 4.16 by 4, to get the price of one tomato. This gives us $1.04. Now, just multiply 1.04 by 7 to get 7.28. Therefore, the price of seven tomatoes is C. $7.28. Hope this helped and have a phenomenal day!

the late fee for library books is $2.00 plus 15 cents each day for a book that is late. If Maria's fee for a late book was $3.20
love history [14]

Answer:

Maria's book was 8 days late

Step-by-step explanation:

According to the information given, you can write an equation that states that 15¢ multiply for the number of days that the book was late plus $2 is equal to $3.20:

0.15x+2= 3.20

x= number of days that the book was late

Now, you have to solve for x:

0.15x= 3.20-2

0.15x= 1.20

x= 1.20/0.15

x= 8

The book was 8 days late.

PLZ ANSWER ASAP! What is the solution of the system of equations? {7/2x−1/2y=9/2 3x−y=5 Enter your answer in the boxes.
Reil [10]

\frac{7}{2} x -  \frac{1}{2} y =  \frac{9}{2}  same \: as \: 7x - y = 9
7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)

7x-y=9
-3x+y=-5 (now add both equations)

7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)

x=1

y=3x-5=3×1-5=-2

y= -2

answer: x=1, y=-2
