Hi there
Let x be the number of miles Karly biked
Dory biked 11 times as many miles as Karly, therefor, Dory = 11x
The total number of miles back by both is 156
The equation will be:
11x + x = 156
Before we can get the number of miles Dory biked, we must first get the number of miles
Karly biked represented by x.
Get the x
12x = 156
12x/12 = 156/12
<span>x = 13 </span>
Karly = x = 13 miles biked
Dory = 11x = 11(13) = 143 miles biked
to check:
11x + x = 156
11(13) + 13 = 156
143 + 13 = 156
<span>156 = 156
i hope it helps have a nice day:)

Step-by-step explanation:
Answer:48.1897 = 48.2
Step-by-step explanation: cos P= 3.8/5.7
P= cos-1 (3.8/5.7)
P=48.1897 = 48.2
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
2sinxcosy = sin(x + y) + sin(x - y) , then
with x = 70 and y = 20
2sin70cos20
= sin(70 + 20) + sin(70 - 20)
= sin90 + sin50
= right side , thus proven
