If a bag has 30 orange marbles then that means it has 42 red marbles
Step-by-step explanation:
If there are 7 red marbles for every 5 orange marbles then what you would do is.
30/5=6
6*7=42
Each marble bag sold by Chris's marbles company contains 7 red marbles for every 5 orange marbles , if a bag had 30 orange marbles Then the bag contains 42 red marbles.
In the problem, we are given that each bag of marbles contains 7 red marbles for every 5 orange marbles. We need to find the number of red marbles when there are 30 orange marbles in the bag.
Let's represent the number of red marbles as R and the number of orange marbles as O.
According to the information provided, we have the following relationship:
R / O = 7 / 5
Now, we are given that the number of orange marbles (O) in the bag is 30. We can substitute this value into the equation:
R / 30 = 7 / 5
To find the number of red marbles (R), we can cross-multiple
R = (7 / 5) * 30
R = 42
Therefore, the bag contains 42 red marbles.
In summary, we used the given ratio of red to orange marbles in the bag to set up a proportion and then solved for the number of red marbles when the number of orange marbles was known. This allowed us to find that there are 42 red marbles in the bag.

Solve this system of equations without graphing and show your reasoning
Answer:
x = 1/5
y = 6
Step-by-step explanation:
System:
{5x + y = 7
{20x + 2 = y
First equation:
5x + y = 7 -> y = -5x + 7
Plug into second equation:
20x + 2 = -5x + 7
Subtract 2 from both sides:
20x = -5x + 5
Add 5x to both sides:
25x = 5
Divde both sides by 25:
x = 5/25 -> 1/5
~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Come back to the first equation:
5x + y = 7
Plus in our x:
5(1/5) + y = 7
Multiply:
1 + y = 7
Subtract 1 from both sides:
y = 6

Step-by-step explanation:
Katherine and Ivan had 96 marbles in all. Katherine lost 24 marbles to Ivan
during a game. At the end of the game, Ivan had twice as many marbles as
Katherine. How many marbles did Ivan have at first?
K. 48-24=24
I. 48+24=72×2= (144) so 144
An equation is formed of two equal expressions. The total number of marbles that Ivan had at the first is 40.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of marbles with Katherine be represented by k, while the number of marbles with Ivan is represented by x.
Given that the total number of marbles available with Katherine and Ivan is 96. Therefore, we can write,
k + x = 96
Solving the equation for k,
k = 96 - x
Further, Katherine lost 24 marbles to Ivan during a game and at the end of the game, Ivan had twice as many marbles as Katherine. Therefore, we can write the equation as,
2(k - 24) = (x + 24)
2k - 48 = x + 24
Substituting the value of k,
2(96 - x) - 48 = x + 24
192 - 2x - 48 = x + 24
192 - 48 - 24 = x + 2x
3x = 120
x = 120/3
x = 40
Hence, the total number of marbles that Ivan had at the first is 40.

Step-by-step explanation:
what is THE partial product ? there is a mistake in your problem description.
it must read "what are valid partial products".
1262×3 has the following partial products :
1000×3 = 3000
200×3 = 600
60 × 3 = 180
2×3 = 6

Answer: -6x
Step-by-step explanation: Since when x is 0, the function's output is 0, the function can only have terms with x in it. You then notice a pattern that x is always being multiplied by -6. You could also use point slope form to solve it, either way you get f(x)=-6x
Answer:
f(x) = -6x
Step-by-step explanation:
The linear equation given in the form of a table is shown as:
[tex]\left[\begin{array}{ccc}x&f(x)\\0&0\\1&-6\\2&-12\\3&-18\end{array}\right][/tex]
Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):
0 ÷ 0 = 8
-6 ÷ 1 = 8
-12 ÷ 2 = 8
-18 ÷ 3 = 8
Because the quotient for each relation is -6, the linear equation can be written as f(x) = -6x.

Type the correct answer in the box. Use numerals instead of words.
Ali has hired Mark and Alexis to work for his shipping company. Mark can
load a truck with packages in 120 minutes. Alexis can load the same
number of packages in 240 minutes.
Mark and Alexis work together on a particular truck, they can load all of the packages in
minutes.
Answer:
80 minutes
Step-by-step explanation:
Work done by Mark in 1 minute = 1/120
Work done by Alexis in 1 minute = 1/240
Work done by Mark and Alexis in 1 minute = 1/120 + 1/240
[tex]= \dfrac{1*2}{120*2}+\dfrac{1}{240}\\\\=\dfrac{2}{240}+\dfrac{1}{240}\\\\=\dfrac{3}{240}\\\\=\dfrac{1}{80}[/tex]
They both can load all the packages in 80 minutes.
