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.

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.

Answer:

Step-by-step explanation:
-2.56 multiplied by 1.2= -3.072
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

what is the partial product for 1,262 x 3
A 600 and 500
B 15 and 180
C 600 and 900
D 180 and 3000
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
