Answer:
miles.
Step-by-step explanation:
Given that a group of hikers walked miles along a hiking trail. Another group of hikers walked that distance with the first group before turning off onto another trail. Now we need to find about how many miles did the two groups of hikers walk with each other.
To find that we just need to find half of
=
=
=
=
=
Hence final answer is miles.
It's a pentagonal pyramid.
<span>7x+1 < 4(x-2) simplify gives
7x+1 < 4x-8 and collect terms...
3x < -9 i'd solve it as an equality
3x = -9 giving
x = -3 see if zero is in the solution set
7*0 +1 < 4(0-2)
1 < -8 false so
x < -3 (doesn't contain zero)
and: x < - 3
I hope this helped!

Multiply both dimensions by a number greater than 1 to enlarge the photo.
example:
20*2= 40
30*2= 60
the new photo is 40inx60in, making it twice as big as the original
to shrink the photo, multiply the dimensions by a number less than 1
Answer:
Step-by-step explanation:
9) 24=6(-x-3)
24=-6x-18
42=-6x
x=-7
10) 75=3(-6n-5)
75=-18n-15
90=-18n
n=-5
11) -3(1+6r)=14-r
-3-18r=14-r
17=-17r
r=-1
12) 6(6v+6)-5=1+6v
36v+36-5=1+6v
36v+31=1+6v
30=-30v
v=-1
13) -4k+2(5k-6)=-3k-39
-4k+10k-12=-3k-39
6k-12=-3k-39
9k=-27
k=-3
14) -16+5n=-7(-6+8n)+3
-16+5n=42-56n+3
-16+5n=45-56n
61=-61n
n=-1
