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:)

Answer:
-multiply both sides by 2, so you will have 2A= h(b+c)
- divide both sides by (b+c), so you will have 2A/(b+c)=h and this is your final answer
First you would have to find the third angle in the triangle which you would do by adding 63+61 and subtracting the resulting number from the total degrees in a triangle. From there, you would calculate x and y using the knowledge that angles on a line equal 180.
Answer:
a (-4/3)
Step-by-step explanation:
I think it is a because in the chart where x is shown all the values are increasing by positive 4 and in the chart where y is displayed it is decreasing by -3.
4/-3 or -4/3
Answer:
y=2
Step-by-step explanation:
first solve those in the brackets then find the square root
2y+3=11
put like terms together
3 goes to the right side
2y=11-3
2=8
y=4
√4=2
y=2
