Answer:
Total number of tablets needs to discharge = 240 tables
Step-by-step explanation:
Given:
Number of days tablet need = 30 days
Number of times per days need = 4 times
Number of tablet per time = 2 tablet
Find:
Total number of tablets needs to discharge = ?
Computation:
⇒ Total number of tablets needs to discharge = Number of days tablet need × Number of times per days need × Number of tablet per time
⇒ Total number of tablets needs to discharge = 30 × 4 × 2
⇒ Total number of tablets needs to discharge = 240 tables

1] y - 3x = -8
[2] y + 9x = 4
-3x + y = -8 9x + y = 4
Solve equation [2] for the variable y
[2] y = -9x + 4
// Plug this in for variable y in equation [1]
[1] (-9x+4) - 3x = -8
[1] - 12x = -12
// Solve equation [1] for the variable x
[1] 12x = 12
[1] x = 1
// By now we know this much :
y = -9x+4
x = 1
// Use the x value to solve for y
y = -9(1)+4 = -5
{y,x} = {-5,1}
Answer:
x = 112
Step-by-step explanation:
We can create two equations 1. one that calculates calories burned and 2.another that calculates minutes:
20*x + 5*y = 1200
x + y = 120
Then we can solve for x
x = 120 - y
then we can plug that into the top equation:
20(120 - y) + 5y = 1200
divide by 5:
4(120 - y) + y = 240
distribute:
480 - 4y + y = 240
and then do all that combining like factors what not and simplify and solve:
480 - 3y = 240
-3y = -240
y = 8
NOW WE CAN JUST PLUG IN THE ANSWER FOR Y TO FIND X
8+x =120
x = 112
D might be the answer I am pretty sure it is D if not then sorry
