Answer:
a = -15
Step-by-step explanation:
a/-3 -6 = -1
add 6 to both sides
a/-3 = 5
now multiply -3 to both sides
a= -15
Surface Area = 2×(5×6 + 5×8 + 6×8) = 236 meters²
Hope this helps! Stay safe, have a good day :D
Answer:
m-14 ≤ 35
Step-by-step explanation:
<span>2x+4y=12
y=1/4x-3
can be re-written as
2x + 4y = 12 4y+2x = 12
4y= x - 12 or -4y -x = 12
------------------
Adding, we get x = 24.
</span>From the given equation y=1/4x-3 (better written as y = (1/4)x - 3), we
get y = (1/4)(24) - 3, or 6 - 3, or 3.
The solution is thus (24, 3).
Here I used the "addition-subtraction method" to solve this system of equations.
Answer:
Step-by-step explanation:
we know that
