The system of equations representing the scenario given are x = 3y + 4 and 0.25y + 0.1x = 4.8.
What does a System of Linear Equations define?Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.
System of linear equations involve two or more linear equations.
Let y be the number of quarters and x be the number of dimes.
Given, number of dimes she has is 4 more than 3 times the number of quarters.
x = 3y + 4
Also, we have that, Sunny has $4.80 in quarters and dimes.
We know,
1 dollar = 4 quarters
⇒ 1 quarter = 1/4 = 0.25 dollar
1 dollar = 10 dimes
⇒ 1 dime = 1/10 = 0.1 dollar
So, we get another equation,
0.25y + 0.1x = 4.8
Hence the system of equations are x = 3y + 4 and 0.25y + 0.1x = 4.8.

Develop a probability model for the spinner shown.
Will give brainliest!
Answer:
Suppose we roll a six-sided number cube. Rolling a number cube is an example of an experiment, or an activity with an observable result. The numbers on the cube are possible results, or outcomes, of this experiment. The set of all possible outcomes of an experiment is called the sample space of the experiment. The sample space for this experiment is \displaystyle \left\{1,2,3,4,5,6\right\}{1,2,3,4,5,6}. An event is any subset of a sample space.
The likelihood of an event is known as probability. The probability of an event \displaystyle pp is a number that always satisfies \displaystyle 0\le p\le 10≤p≤1, where 0 indicates an impossible event and 1 indicates a certain event. A probability model is a mathematical description of an experiment listing all possible outcomes and their associated probabilities. For instance, if there is a 1% chance of winning a raffle and a 99% chance of losing the raffle, a probability model would look much like the table below.
Outcome Probability
Winning the raffle 1%
Losing the raffle 99%
The sum of the probabilities listed in a probability model must equal 1, or 100%.

Answer:
B & C
Step-by-step explanation:
Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.
A-(5)(0.6)*7=21
B-(4/5)(15)+8=(0.8)(15)+8=20
C-4(8+2)/2=4(10)/2=40/2=20
D-14+4(2+3)=14+4(5)=14+20=34
If you need any clarification just lmk :)

8 x + 40 > -16
A x>7
B x<7
C x>-3
Dx<-3
Answer:
It's A
Step-by-step explanation:
You have to subtract 40 from both sides
Then divide both sides by 8
And then you have your answer.
The number line shows values of x that make the inequality x > 1 true.
