Jason is training to run in a marathon. His goal for this week is to run a minimum of 330 miles. So far this week, he has alread
y run 15 miles. Which inequality could be used to determine the number of miles, m, he would need to run each day for 4 more days to achieve his goal?
1 answer:
Answer:
4m ≥ 330 - 15
Step-by-step explanation:
Given that :
Target of the week = ≥ 330 miles
Total distance already covered = 15 miles
Number of miles, m required each day for 4 more days
Distance already covered + number of days left * miles (m) ≥ 330 miles
15 miles + 4m ≥ 330 miles
4m ≥ 330 - 15
4m ≥ 315
m ≥ 315 / 4
m ≥ 78. 75 miles

Answer:
Step-by-step explanation:
If x is inversely porportionaly to y, then for some constant k,
Since y is 4 when x = 18, k is equal to 4*18=72, so the equation is:
Answer:
- first distribute the 5 to the d and 4
- 5(d+4) then becomes 5d+20
- then subtract 20 from both sides of the equation
- -5=5d+20 is now -25=5d
- lastly divide 5 from both sides
- -25=5d is now -5=d
- hope this helps!
