Answer:
n divided by 8 Plus 12 = 64 n=416
Step-by-step explanation:
If the answer can be left in a fraction than this is the solution: 2×5/8=5/4
5/4-1/3=11/12
if you mean the answer must be left in a whole number than.. I don't really know how to do it

Answer:
b=5
Step-by-step explanation:
−4+bx=2x+3(x+1) (expand parenthesis first, i.e PEDMAS)
−4 + bx = 2x + 3x + 3
−4 + bx = 5x + 3 (move all x terms to one side and constants to another)
5x - bx = - 4 -3
5x - bx = - 7 (factor out x)
(5 - b)x = - 7
x = -7 / (5-b)
we can see that 5-b is in the denominator. Recall that for a fraction, the denominator cannot be zero otherwise the expression is undefined. (i.e no solutions)
hence the expression is undefined if,
(5-b) = 0
or b = 5
Answer:
after 7th day the temperature changes - 8.4 degrees.
Step-by-step explanation:
Each day, the temperature changes - 1.2 degrees. Then
- after 1st day the temperature changes - 1.2 degrees;
- after 2nd day the temperature changes - 2.4 degrees;
- after 3rd day the temperature changes - 3.6 degrees;
- after 4th day the temperature changes - 4.8 degrees;
- after 5th day the temperature changes - 6 degrees;
- after 6th day the temperature changes - 7.2 degrees;
- after 7th day the temperature changes - 8.4 degrees.
