Answer:
He would need to walk the dog 6 more times because 8 times 11 is 88 and if he has already walked the dog 5 times you would subtract that from 11 to get 6. So the answer would be 6
Step-by-step explanation:
8·11= 88
11-5= 6
Answer:
30%
Step-by-step explanation:
One simple way of finding out discounts is to simplify our answer by starting with 10% and subtracting from that.
If the original price were to have a 10% discount, it would be 4.70/10 for .47 per 10% off.
10% gives us 4.23, so let's take another 10% off by doing 4.23-.47, which is equal to 3.76. While lower, it's not our answer so lets do another 10%
3.76-4.7 = $3.29
With a total of 3 10%'s taken off, or in this case, 30% off, we can conclude that the discounted prices of $3.29 is 30% of the original price.
Answer:
x = 2
Step-by-step explanation:
Given
1 + x = 7 - 2x ( add 2x to both sides )
1 + 3x = 7 ( subtract 1 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Answer:
3.9 miles
Step-by-step explanation:
Use phytagoras theorem
c²=a²+b²
4²=1²+b²
16=1+b²
b²=16-1
b²=15
b=
b= 3.872
≈3.9miles
