First, distribute the (1/2) into (4x+12) by multiplying them.
The equation becomes:
2x + 6 + 5x = 30
On the left side, combine “like terms” through addition.
7x + 6 = 30
Subtract 6 from both sides:
7x = 24
Finally, get x alone by dividing both sides by 7:
x = 24/7, or if you wanted to round the decimal answer, it’s about 3.429.
Answer:
21.78 meters
Step-by-step explanation:
Divide 326.7/15
Another way to write this is:
x = 23y + 5
xy = 6732
Now plug in the first equation into the second:
(23y + 5)y = 6732
23y^2 + 5y - 6732 = 0
Either use quadratic equation or factor:
(y - 17)(23y + 396) = 0
y = 17 or -396/23
You know you can automatically eliminate the second y because it's negative and you need the two integers to multiply to a positive number (6732).
Plug y = 17 back into either equation (second might be easier):
17x = 6732
x = 396
Answer:
a
Step-by-step explanation:
it LOST 950, which make the integer negative. in the second part of the answer, look for "earn", because to undo loss, you must gain.
Happy new years!
Step-by-step explanation:
n + 8 ≤ 13
n ≤ 13 - 8
n ≤ 5
n = {5,4,3,2,etc}
