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:)

That's a true statement, simply because ... I believe ...
that's the definition of "similar" figures.
Answer:
It would take 4 weeks
Step-by-step explanation:
We can solve this problem most easily by forming it into an equation. We could represent weeks as <em>w.</em>
Since you train 5 more minutes every week, we could represent that as 5<em>w</em>, showing that you work 5 minutes times the number of weeks you worked out.
The constant would be adding 10, since you started out working 10 minutes a day. Now lets just write the equation!
10+5<em>w</em>=30
All we have to do is solve.
Subtract 10 on both sides to cancel out the positive 10.
5<em>w</em>=20
Now just divide both sides by 5 to isolate the <em>w</em>.
w=4
It would take him 4 weeks
Hope this helps!
Answer:15 inches by 27 inches
Step-by-step explanation:
A rectangle has a width of 5 inches and a length of 9 inches. This means that the original length of the rectangle is 9 inches. The original width of the rectangle is 5 inches.
The rectangle was dlated by
a scale factor of 3. It means that the dimensions of the length of the rectangle and the width of the rectangle were increased 3 times.
The new length of the rectangle would be 3 × original length. It becomes 3×9 =27 inches
The new width of the rectangle would be 3 × original width. It becomes 3×5 =15 inches
