Answer:
first one
Step-by-step explanation:
Tracey bought 10 movies
some cost 13 and the others 16
Let x be the movies that cost 13 and y ones that cost 16
we can state that
since Tracey both ten
since the total price is 139
so the system is :

Answer:
slope: -8
y-intercept: 11
Step-by-step explanation:
x = 1, 3
y = 2, -5
If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
The measure of the m∠IUV using the addition postulate is equivalent to 82 degrees
<h3>Lines and angles</h3>
A line is defined as the shortest distance between two points while an angle is the point where two lines meet.
Given the following measure of angles
m∠TUI = 65° and
m∠TUV = 147°
Required angle
m∠IUV
Using the addition postulate below
m∠TUV = m∠TUI + m∠IUV
Substitute the given parameters
147 = 65 + m∠IUV
m∠IUV = 147 - 65
m∠IUV = 82 degrees
Hence the measure of the m∠IUV using the addition postulate is equivalent to 82 degrees
