I'll give brainliest if correct/Maria, Jose, and Trey sent a total of 124 text messages over their cell phones during the weekend. Jose sent 3 times as many messages as Trey. Trey sent 9 fewer messages than Maria. How many messages did they each send?
Answers
Answer:
Maria sent 32 messages
Jose sent 69 messages
and Tray sent 23 messages
Step-by-step explanation:
m = Maria
j = Jose
t = Trey
m+j+t = 124
j = 3t
t+9 = m $\Rightarrow$ t = m - 9
By substituting the value of t (third equation) into the second equation, we get:
j = 3(m - 9) = 3m - 27.
Finally, by sticking in the values of j, and t we just found out into the first equation, we get:
m + (3m - 27) + (m - 9) = 124
4m - 27 + m - 9 = 124
5m - 36 = 124
5m = 160
m = 32.
So, j = 69,
and t = 23.

Use the drawing tools to graph the solution to this system of inequalities on the coordinate plane.
y> 2x + 4
x+y s6
Answers
The inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have two inequalities:
y > 2x + 4
x + y ≤ 6
We can plot the above inequality on the coordinate plane.
The inequalities representing the region between the two lines the lines are:
y = 2x + 4
x + y = 6
y > 2x + 4 (dashed line on the graph)
x + y ≤ 6 (solid line on the graph)
Thus, the inequalities y > 2x + 4 and x + y ≤ 6 can be plotted on the coordinate plane as shown in the picture.

A bacteria grows exponentially so that it doubles every 12 days. There are 500 bacteria initially. Write a function that models the number of bacteria after t days.
Note is is NOT doubling every day! Careful.
Find the number of bacteria after 60 days.
Answers
Answer:
16000 bacteria after 60 days
Step-by-step explanation:
60 divided by 12 = 5
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
The function is, f(x) = 2x/12*t
And, the number is 16000 bacteria after 60 days.
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, given that,
A bacteria grows exponentially so that it doubles every 12 days
let, initially the number of bacteria = x
after 12 days = 2x
i.e. after t days = 2x/12*t
So, the function is, f(x) = 2x/12*t
Now, we have,
60 divided by 12 = 5
So, the number of bacteria will be,
500 x 2= 1000
1000 x 2 = 2000
2000 x 2 = 4000
4000 x 2 = 8000
8000 x 2 = 16000
Hence, the number of bacteria after 60 days is 16000.

56 = -10 + 2x
Answers
Move the variable towards the left side and transition it’s sign in this problem
-2x+56=-10
Move the constant heading towards the right side and proceed to put a transition within it’s sign
-2x=-10-56
Now that you have that installed, you must calculate the difference here
-2x=-66
Now you divide -2 in both sides that has taken place in
x=33, therefore x=33 in 56=-10+2x
To check you can do 56=-10+2(33) and it will give you the right answer
Answer: x= 33
i subtracted -10 away from 56 and i got 66, then i divide 66 by 2x and got 33x.. which is your answer ;)

Molly can use her mode to show that she is doing better than the other three students.
Ashlee’s mode is 94, Belen’s mode is 79, Molly’s is 98, and Sofia doesn’t have a mode. The highest is Molly, so she should use her mode to show she is doing better.
