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.

Lebron James's Free Throw % is 75%
What is the probability that he makes 6 Free Throws in a row?
Answer as a decimal rounded to 2 places.
Answer: 0.18
Step-by-step explanation:
From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:
= 75% × 75% × 75% × 75% × 75% × 75%
= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4
= 729/4096
= 0.18

Find the length of the hypotenuse, c in this triangle
Answer:
c = 5cm
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 3^2 = c^2
16 + 9 = c^2
25 = c^2
do the square root of 25 and c to solve for c
the square root of c^2 is c
therefore, c= 5cm

Step-by-step explanation:
The area of a rectangular wall of a barn is 153 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn.
Answer and Step-by-step explanation:
Area (A) = 153
Length (l) = 8 + w
Width (w) = w
A = lw
153 = (8 + w)(w)
153 = [tex]w^{2} + 8w[/tex]
0 = [tex]w^{2} + 8w[/tex] - 153
[tex]w^{2} -9w + 17w - 153[/tex]
(w - 9)(w + 17)
w = 9
w = -17
We can't have a negative length, so we only use 9.
w equals 9.
That means l equals 17 (9 + 8 = 17).
Length = 17
Width = 9

Truck drivers report the mileage or the number of miles (M) traveled per gallon of gas (G) for each trip. Which driver went the farthest on one gallon of gas.
Answer:
B. AndyStep-by-step explanation:
Kelly's mileageThis is proportional relationship, so one pair of coordinates is enough for our calculation, point (20, 50):
m = 50/20 = 2.5 gAndy's mileageUse one pair of points from the table to calculate (15, 78.75):
m = 78.75/15 = 5.25 gRick's mileage is given:m = 4.8 gComparing, we see Andy's mileage is largest.
Andy will travel farther than the other drivers.

Suppose 35% of students in a class have blue eyes. Five blue-eyed students join the class. Now 48% of the students have blue eyes. How many students were originally in the class?
Answer:
x : 35
x +5 : 48
35x+175=48x
175= 48x-35x
13x=175
x=175/13
x=13 students
JUST HELP ME ITS DUE IN5 MINUTES:"( ASAP <3
Answer:
A. 25%
25% is equivalent to 1/4 and when you multiply 75 by 4 you get 300. Which means 75 is equivalent to 1/4 and 1/4 is equivalent to 25%. So the answer is 25%. I'm so sorry if this explanation is bad
Solve the system of equations using elimination. How many solutions does the system have?
15j + 12k = 18
5j + 4k = 6
Responses
A. One solution, j = 3, k = 3
B. No solution
C. One solution, j = 10, k = 8
D. Infinitely many solutions
Answer:
I hope it helps u
Step-by-step explanation:
Let's solve your system by elimination.
15j+12k=18;5j+4k=6
Multiply the second equation by -3, then add the equations together.
(15j+12k=18)
−3(5j+4k=6)
Becomes:
15j+12k=18
−15j−12k=−18
Add these equations to eliminate j:
0=0
Answer:
Infinitely many solutions

Riley buys a fridge, which he can pay for using the following options. A 9 payments of $183 B $1559 up front Which option is cheaper and by how much?
Answer:
Option B is cheaper by $88.
Step-by-step explanation:
It is given that:
Option A for buying fridge,
9 payments of $183
Total cost = $1647
Option B for buying fridge
Upfront payment = $1559
Thus,
1559 < 1647
Option B is cheaper.
Difference = 1647 - 1559 = $88
Therefore,
Option B is cheaper by $88.
