C=-160/9+5f/9 I think that's the answer to your qeustion
Answer:
12
Step-by-step explanation:
red hat, black shirt, black pants
red hat, white shirt, black pants
red hat, striped shirt, black pants
black hat, black shirt, black pants
black hat, white shirt, black pants
black hat, striped shirt, black pants
that is six different combinations without the use of the pair of blue pants, thus you should be able to just do all those combinations over again with just blue pants leading to a total of 12 combinations. I think lol
3 2/3 = 3x3=9+2=11/3
4 2/5= 4x5=20+2=22/5
1st is to make the numbers into ratios. Basically taking the two numbers and putting them in the middle. I’ll do the 1st 15:36.
Next you put it into a fraction: 15/36
Put in the comments if you want me to do all or if you have any questions!
Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
