Hey there! Thanks for asking your question on Brainly!
In order to solve this equation, we'll first need to isolate n. To do so, we will subtract 2 from both sides.
2 + n = 16
n = 14
In subtracting 2 from both sides, we were able to isolate n. Since n does not have a number in front of it, we are finished! The answer is n = 14.
Hope this helps!! :)
You would do 56,233 times 12 plus 7,867 times 12. Getting you 674,796 plus 94,404. The total answer, or sum, is $769,200.
Answer:
4. No solution
Step-by-step explanation:
To solve a system of equations, find the (x,y) solution that satisfies both equations. One method that can be used is substitution. It is done by substituting one function into the other function and simplify.
Substitute y = 4x - 6 into 8x - 2y = 14.
8x - 2(4x - 6) = 14
8x - 8x + 12 = 14
12 = 14 FALSE
Since the variable was eliminated and a false statement was found, there is no solution to this system.
Solve 3 and 5 similarly. If the variable is eliminated again, but a true statement is fund then the solution is infinite. If the variable is not eliminated then substitute it back into one equation to find the other.
length = 15
let the width = w then length = 2w - 3
Perimeter = 2(length + width)
= 2(2w - 3 + w) = 2( 3w - 3) = 6w - 6 = 48
hence 6w = 48 + 6 = 54 ⇒ w =
= 9
Thus length = 2w - 3 = (2× 9) - 3 = 18 - 3 = 15
