The two unknown variable in the two given equations are "x" and "y".
3y + 3x = 24
Dividing both sides by 3 we get
y + x = 8
x = 8 - y
Putting the value of y in the second equation we get
6y + 3x = 39
Dividing both sides by 3 we get
2y + x = 13
2y + 8 - y = 13
y = 13 - 8
= 5
Putting the value of y in the first equation we get
y + x = 8
5 + x = 8
x = 8 - 5
x = 3
So the value of x is 3 and the value of y is 5. I hope the procedure is clear enough for you to understand.
Answer:
0.095 miles per minute
Step-by-step explanation:
If Sophie traveled 25 feet in 3 seconds, then in 1 second she will travel
25/3 = 8.333 ft
But in 60 seconds make 1 minute, so in 1 minute, she will travel
(25/3) × 60 = 25 ×20
= 500 ft
Therefore in miles/minute, she was going
500/5280 = 0.095 miles per minute
Answer:
The answer is 16x + 7
Step-by-step explanation:
First you want to add all of the like terms.
(8x + 10 + 12x + 7) - (4x+10)
20x + 17 - (4x + 10)
Now you want to subtract all of the like terms
16x + 7
Answer: The movie theater sold 434 a day
Step-by-step explanation:
How I got 434 a day
So
If you multiply 434 x 6 = 2,604
so they sold 2,604 in 6 days.
Let me know if I did something wrong.
