Answer:
x= 0.78 (rounded to the hundredth)
Step-by-step explanation:
-5.5x + 0.46 = -3.94
You need to isolate x so the easiest thing to do is subtract 0.46 and move it to the other side of the equal sign.
-5.5x= -3.84 - 0.46
-5.5x = -4.3
divide -5.5 to get x alone
x= -4.3/-5.5
x= 0.78

Answer:
15 x 8 = 120
Step-by-step explanation:
There are 15 tables and 8 people sit at each the number of people that would be able to go would be 120
We are told donut sales is described by an arithmetic sequence of 6 terms whose sum is 150 and common difference is 6. If we split this sequence into two groups of 3 terms, the sum of the first group will differ from the sum of the second group by
(number of terms)²×(common difference) = 3²×6 = 54
Then if x represents the number of donuts sold in the first 3 hours, the total number of donuts sold is
x + (x + 54) = 150
2x = 150 - 54
x = 96/2 = 48
The number of donuts sold in the first three hours is 48.
