The relationships are:
20 large marshmallows = 3 cups cereal
3 mini marshmallows = 1 large marshmallow
Therefore if there are 6 cups cereal, so we also get 40
large marshmallows. Since for every 1 large, we need 3 mini, hence:
mini marshmallows = 40 * 3 = 120
Answer:
True
Step-by-step explanation:
A system of equations can be solved by Translating the system of equations into a matrix by following theses steps
- list all coefficients in a single matrix
- multiply the coefficient matrix with the variables matrix
- enter answers into a new matrix
write out the resulting answer in form of equations.

Where xx is the number of small boxes sent and yy is the number of large boxes sent.
Step-by-step explanation:
Let be xx the number of small boxes sent and yy the number of large boxes sent.
Since each small box can hold 20 books (20x20x ), each large box can hold 30 books (30y30y )and altogether can hold a total of 280 books, we can write the following equation to represent this:
20x+30y=28020x+30y=280
According to the information provided in the exercise, there were 4 times as many large boxes sent as small boxes. This can be represented with this equation:
y=4xy=4x
Therefore, the system of equation that be used to determine the number of small boxes sent and the number of large boxes sent, is:
\{ {{20x+30y=280} \atop {y=4x}} .{
y=4x
20x+30y=280
.
