Answer:
1. -5
2. 0
Step-by-step explanation:
<em>1.</em> Distribute the Negative Sign:
=a−2a+−1(3a−(4a−5))
=a+−2a+−1(3a)+−1(−4a)+(−1)(5)
=a+−2a+−3a+4a+−5
Combine Like Terms:
=a+−2a+−3a+4a+−5
=(a+−2a+−3a+4a)+(−5)
Answer:
=−5
<em>2. </em>Distribute:
=(13)(5)+(13)(−t)+−5+t+(−12)(5)+(−12)(−t)
=65+−13t+−5+t+−60+12t
Combine Like Terms:
=65+−13t+−5+t+−60+12t
=(−13t+t+12t)+(65+−5+−60)
Answer:
=0
Answer:
(Choice A) 5M
Step-by-step explanation:
Let total no. of e-mails in inbox be x
Since she read 80 % of mails i.e 80 % of x
⇒
⇒
⇒
So, she read 0.8x e-mails.
So, remaining email = total e-mails - read e-mails

Since we are given that Danette still has M unread e-mails.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Thus the expression represent the number of e-mails Danette had in her inbox before she started reading is 5M.
Hence Choice A is correct.

Answer:
c. 2
Step-by-step explanation:
Defining two angles of a triangle means you know the values of all of the angles. When all angles are known and the side opposite one of them is known, then the triangle is completely determined.
In this case, the angle opposite the given side can be either of the two given angles, so two triangles are possible.
__
If the two angles have the same measure, then only one triangle is possible.
Well for every 9 Tuesday’s that she goes, she gets 3, so since 9•4 equals 36, then to solve you multiply 3 times 4, equals 12, so she will most likely get 12 coupons in the next year
