The difference between two numbers is 3. The sum of the same tow numbers is 13. What is the
Ber [7]

Answer: 40

Step-by-step explanation:

Let the two numbers be a and b.

Therefore,

a - b = 3 ....... i

a + b = 13 ....... ii

From equation I, a = 3 + b

Put a = 3+b into equation ii

a + b = 13

3 + b + b = 13

3 + 2b = 13

2b = 13 - 3

2b = 10

b = 10/2

b = 5

Since a = 3 + b

a = 3 + 5

a = 8

The product of the numbers will be:

= 8 × 5

= 40

ss7ja [257]

You will need 3.333.... cups of rice to make 10 servings of casserole.

<u><em>Explanation</em></u>

The recipe which makes 6 servings of casserole, needs 2 cups of rice.

Suppose, you need x cups of rice for making 10 servings of casserole.

Now, the equation according to <u>the ratio of "cups of rice" to the "servings of casserole" </u>will be.....

\frac{x}{10}=\frac{2}{6}\\ \\ 6x= 2*10=20\\ \\ x=\frac{20}{6}=3.333.....

So, you will need 3.333.... cups of rice to make 10 servings of casserole.

How many solutions does the system formed by x - y = 3 and ay + 3a = 0 have for a non zero number a? Explain and show how you ge
dlinn [17]
Solve both equations for y:
x-y=3 \ \ \ |-x \\&#10;-y=-x+3 \ \ \ |\times (-1) \\&#10;y=x-3 \\ \\&#10;ay+3a=0 \ \ \ |-3a \\&#10;ay=-3a \ \ \ |\div a, a \not= 0 \\&#10;y=-3

Set the expressions equal to each other:
y=y \\ x-3=-3 \ \ \ |+3 \\&#10;x=0 \\ \\&#10;(x,y)=(0,-3)

So, for every nonzero number a the system of equations has one solution.
