answer: well i thing subtracting and adding integers are related because they  both can be solved using an number line

We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.


To add integers having the same sign, keep the same sign and add the absolute value of each number.


To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.


Subtract an integer by adding its opposite.

3. x + 4y = 30<br> x - 2y = 0
kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

Leanne Raymond Montel and Emily body gift for their soccer coach the total cost of the gift including tax was $55.80 Montel paid
Flauer [41]

Solution: The total cost of the gift including the tax = $55.80

The amount paid by Montel = $14

The amount paid by Raymond is

\frac{1}{3} \times 55.80

18.6

Therefore, Raymond paid $18.6

The amount paid by Emily is

25% of 55.80

0.25 \times 55.80 = 13.95

Therefore, Emily paid $13.95

We also know that the remaining amount is paid by Leanne.

Therefore, the remaining amount is:

Total amount - Amount paid by Montel, Raymond and Emily

55.80 -(14+18.6+13.95)

55.80 - 46.55

9.25

The amount paid by Leanne is $9.25

We clearly see, Raymond has paid $18.6, which is the greatest part of the cost $55.80

Pie

Answer:

Step-by-step explanation:

Givens

Greeting Card = 3.79

Total Cost = 5.11

Post cards = x

Equation

Total Cost = Greeting Card + 4x

Solution

Substitute the gives into the equation

5.11 = 3.79 + 4x                       Subtract 3.79 from both sides

5.11 - 3.79 = 3.79 - 3.79 + 4x  Combine

1.32 = 4x                                  Divide by 4

1.32/4 = 4x/4

x = 33

Each post card costs 0.33 dollars
