Answer:
-1557
Step-by-step explanation:
a+14d=143
a+12d=183
--------------------
2d= -40
d= -20
a=183+240=423
a(100th)= 423+99*-20=423-1980= -1557
I hope that help =)

Answer: $11
Step-by-step explanation:
To have the same:
11+8=19
19×2=38
Answer:
<em>3. x = 8</em>
<em>4. lines r and s</em>
Step-by-step explanation:
3.
The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.
5x + 10 + 130 = 180
5x + 140 = 180
5x = 40
x = 8
4.
Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
Answer:
<em>12.5w = 419.38</em>
<em>and</em>
<em>15.5w = 419.38</em>
Step-by-step explanation:
find the total cost of all the computer parts.
= 259.99 + 2* 39.95 + 79.49 = $419.38
Shana will save $12.50 per week and Marie will save $15.50
per week
therefore we can create two inequalities
<h2><u> Shana:</u></h2>
12.50 * w = 419.38
<em>12.5w = 419.38</em>
w = 419.38/12.5
w = 33.5504
<h2><u>Marie</u></h2>
15.50*w = 419.38
<em>15.5w = 419.38</em>
w = 419.38/15.5
w =27.0568
