Answer:
25 more hours
Step-by-step explanation:
First you need to make an equation
200+12x=500
Then you solve it by:
Subtracting 200 from both sides
12x=300
Then divide both sides by 12
x=25
Then you can check your answer by plugging in the number
200+12x25=500
Hope this helps
Answer:
0.3 L
Step-by-step explanation:
3 L / 10 students = 3/10 = 0.3 Liters per student
Find 110% of 40
we already see the 100, so it's 40 + x
so 10% of 40 is 40*.10 which is 4
so it's 40+4
44 is 110% of 40.
Another way of finding this is just multiplying 40*1.10 on a calculator or by hand.
Answer: 10
Step-by-step explanation:
If Sean swung 25 times, and only hit the ball 15 times, he missed 10 times. 25-15=10
-3+2x = -6 (negative and negative changes to positive (+))
2x = -6+3
2x = -3
x = -3/2
