Answer:
I believe the answer is A
He is correct. If the second equation is multiplied by 2 and added to the first equation, the result is 0=3 , which means the system has no solution.
Answer:
The cost for each movie is $2
The cost for each video game is $6.5
Step-by-step explanation:
Let
x-----> the cost for each movie
y-----> the cost for each video game
we know that
5x+2y=23 -----> equation A
3x+8y=58 -----> equation B
Solve the system of equations by graphing
Remember that
The solution of the system of equations is the interception point both graphs
The solution is the point (2,6.5)
see the attached figure
therefore
The cost for each movie is $2
The cost for each video game is $6.5
Answer:
The fencing will cost $334
Step-by-step explanation:
To know how much the fencing will cost. We need to calculate the total length around the garden.
This is same as the circumference of the circular garden.
Mathematically, the circumference C of a circle can be calculated using the formula
C = 2 × π × r
where r = 15 feet
C = 2 × 22/7 × 15
C = 94.3 feet
Now the fencing cost $3.54 per foot
Total cost = 94.3 × 3.54 = $333.822
or simply $334 to the nearest whole dollars

Answer:
C. 720
Step-by-step explanation:
10 - 3 is 8 so you multiply all the numbers from 10 through 8
10 * 9 * 8 = 720
That is the answer. Hope it helped!
