Answer:
b. 6
Step-by-step explanation:
Answer:
x=6
y=1
Step-by-step explanation:
3x=18, so when you divide 3x by 3 to get x alone, you also divide the other side and 18 divided by 3 is 6. now you know that x equals 6. then you plug x back into either equation to solve for y. I chose to plus into x-3y=3. it would read 6-3y=3. you then subtract 6 from both sides and get that -3y=-3. therefore when you divide both sides by -3, you get that y=1
Answer:she will earn $200 in 5 weeks
Step-by-step explanation:
Susan takes care of a child for 2 hours after school each weekday and 6 hours on Saturday. There are 5 school days in a week. Total number of hours that she spends in taking care of the child during the weekdays would be 5×2 = 10 hours.
Total hours for the week would be
10 + 6 = 16 hours
Total amount of hours in 5 weeks would be
5 × 16 = 80
If she earns 2.50 per hour, it means that in 80 hours, she would earn
2.5 × 80 = $200
3 * 7 * 67
