Answer:

3:0.5, 9:1.5, 6:1, 33: 5.5, 12:2, 39:6.5, 15:25.

the unit rate of eggs per 1 kg of flour = 6 eggs/1 kg of flour

Step-by-step explanation:

Usually tables go in ascending numerical order...the numbers only go up, reading from right to left. But the math for this has the numbers kind of jumping around.

3/0.5 = 9/x, then cross-multiply,

3x = 9(0.5)

3x = 4.5 then divide by 3

x = 1.5

--------------------------

3/0.5 = x/1

3 = 0.5x

6 = x

----------------------------

If you need me to keep showing the math for the rest of the table, let me know.

What is the solution to the system of equations below? y = one-half x minus 4 and y = negative 2 x minus 9 (–2, –5) (–2, –3) (2,

Maurinko [17]

We have been given a system of equations $y=\frac{1}{2}x-4$ and $y=-2x-9$ . We are asked to find the solution of our given system of equations.

To solve our system of equations, we will equate both equations as:

$\frac{1}{2}x-4=-2x-9$

$\frac{1}{2}x-4+4=-2x-9+4$

$\frac{1}{2}x=-2x-5$

$\frac{1}{2}x+2x=-2x+2x-5$

$\frac{1}{2}x+\frac{4}{2}x=-5$

$\frac{1+4}{2}x=-5$

$\frac{5}{2}x=-5$

$\frac{2}{5}\cdot \frac{5}{2}x=-5\cdot \frac{2}{5}$

$x=-2$

Upon substituting $x=-2$ in equation $y=-2x-9$ , we will get:

$y=-2(-2)-9$

$y=4-9$

$y=-5$

Therefore, the solution of our given system of equations would be $(-2,-5)$ and option A is the correct choice.

Find the area of the circle if the square has an area of 900 in2. Give your answer in terms of pi

shusha [124]

There is no attached picture, but I guess it is like the one I attached.
If so, the first thing is finding the side measure:
$A_{square}=l^2 \\ l= \sqrt{A} = \sqrt{900} \;\;\Rightarrow l=30\;in$
Now, radius is half this measure: 15 in.
And circle area is:
$A_{circle}=\pi r^2=\pi\cdot(15)^2\:\;\Rightarrow A_{circle}=225\pi\;in^2$

PLEASE HELP 100 PTS!

Dafna11 [192]

Answer:

infinite solutions

Distributive Property

Step-by-step explanation:

5x + 3(x − 5) = 6x + 2x − 15

Distribute

5x+3x -15 = 6x+2x -15

Combine like terms

8x -15 = 8x-15

Subtract 8x from each side

8x-8x-15 = 8x-8x-15

-15=-15

This is always true so there are infinite solutions

We used the Distributive Property

And the Subtraction Property of Equality

You have 8 shopping trips to make this week. You have time to make any 4 of them today. In how many ways can you select the four

kumpel [21]

Answer:

1680 ways

Step-by-step explanation:

In this question, we are tasked with finding the number of ways in which we can select 4 trips out of 8 to make today.

Let us label the the trips we are to select as A B C D, one after the other

For selection A, we have 8 different trips waiting to be selected

For selection B, we have 7 trips to select from

For C, we have 6 to select from

while for D, we have 5 to select from. Thus, the total number of ways in which we can select these trips can be calculated as = 8 × 7× 6× 5 = 1,680 ways
