Your favorite breakfast cereal contains a toy dinosaur in each box. There are four different dinosaur toys in the complete colle

ction, and each one has an equal chance of being in each box.
You want to figure out what the probability is that you will get more than one tyrannosaurus rex if you buy five boxes of cereal. Which experiment could be used to simulate this situation?
A) You flip a coin 5 times and record the number of times you get tails. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more tails.
B) You draw 5 cards from a deck of cards and record how many spades you get. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more spades.

C) You spin a 5-color spinner 4 times and record how many times you get a blue. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more blue spins.
D) You put 5 different colored marbles in a bag. You draw 4 marbles out and record how many are red. You do 10 trials of the experiment, then calculate the percentage of trials that resulted in 2 or more red marbles.

Solve the system using the substituiton method<br> branliest offered<br> 3x-7y=10<br> x-4y=5
fiasKO [112]
Hi there!

To solve this problem using substitution, we need to set x equal to a value and substitute it into the other equation.

Since
x - 4y = 5,
x = 5 + 4y

3x - 7y = 10
3(5 + 4y) - 7y = 10
15 + 12y - 7y = 10
15 + 5y = 10
5y = -5
y = -1

Now that we know y is -1, we can substitute it back into the equation to find x:

y = -1
x - 4y = 5
x - 4(-1) = 5
x - (-4) = 5
x + 4 = 5
x = 1

So, your answers are x = 1 and y = -1.

Hope this helps!
