Answer:
x is equal to or greater than 38.
Step-by-step explanation:
use the equation 300+12x to find the amount of money in total dependent on x, the number of hours she worked.
To write .065 as a fraction you have to write .065 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.065 = .065/1 = 0.65/10 = 6.5/100 = 65/1000
Answer:
Step-by-step explanation:
The cost per sandwich when 3 are delivered is $20/3 or $6.67 each.
The cost per sandwich when 4 are delivered is $26/4 or $6.50 each.
The average cost per sandwich changes with the number delivered, so it is not proportional. The cost decreases per sandwich as the volume of sandwiches increases. One can't predict the cost of 6 delivered sandwiches based on the information provided. If it were proportional, the cost could be calculated on the basis of the slope of the line. If all sandwiches cost $6.50 each, regardless of the volume ordered, the slope of a line relating number ordered and total cost would have a constant slope of 6.50. That isn't the case in this problem. The slope keeps changing.
Answer:
3/8
Step-by-step explanation
Convert 3/4 to 6/8 to make it easier subract since this problem asks how much he has left.
So 6/8-3/8=3/8
