Answer:
ax+b=c
Step-by-step explanation:
The appropriate restriction on the literal equation ax+b=c if you intend to solve for x is that a cannot be equal to zero. Otherwise, the equation becomes undefined and cannot be solved for x.
Answer:
Step-by-step explanation:To solve the literal equation ax + b = c for x, you would typically want to isolate x on one side of the equation. The appropriate restriction in this case is that 'a' should not be equal to 0, because if 'a' were equal to 0, you would have 0x + b = c, which simplifies to b = c. This would mean there's no 'x' variable to solve for, and the equation would have no solution or would be true for any value of 'c'. So, the restriction is that 'a' must be nonzero for the equation to be solvable for 'x'.
change per week?
The average change per week is 3 cents per week if, over a 6-week period, the price of a gallon of gas increases by 18 cents.
It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that:
Over a 6 week period, the price of a gallon of gas increased by 18 cents.
Let x be the average change per week.
The numerator, which is found at the top of the fraction number, is referred as the numerator, and the denominator, which is found at the bottom of the fractional number, is referred as the denominator.
The value of x can be calculated as follows:
x = 18/6
x = 3 cents per week
Thus, the average change per week is 3 cents per week if, over a 6-week period, the price of a gallon of gas increased by 18 cents.

Answer:
Bicycle: 30 miles/hour
Scooter: 40 miles/hour
Step-by-step explanation:
Let the speed of the bicycle be s,
Then the speed of the scooter is:
s + 10
Distance = speed × time
Distances covered:
Bicycle: (s)(5½) = 5.5s
Scooter: (s + 10)(3) = 3s + 30
Total:
5.5s + 3s + 30
8.5s + 30
8.5s + 30《285
8.5s《255
s《30
s + 10《40
