Step-by-step explanation:
- 2(a-b) its yr question
- 2 & (a-b)is in the form of multiply
- so, first multiply a by 2 it becomes 2a and - sign is greater so, it will be - as it is then multiply b by 2 it becomes 2b
- now write yr ans =2a-2b

Answer:
x <= -6.33333
(>= is greater than or equal to)
(<= is less than or equal to)
Step-by-step explanation:
7 - 3(x+5) >= 11
7 - 15 - 3x >= 11
-8 - 3x >= 11
-3x >= 19
x <= 19/-3
x <= -6.33333

With isosceles triangles the angles attached to the different side are equal. So like in #1, angle S & U are equal.
Inner angles of a triangle add to get 180°. 54 + 54 =108, 180 - 108 = 72 Angle T = 72
Answer:
170
Step-by-step explanation:
Given
Tickets = $2 per single and $3 per couple
Total tickets = 365
Total receipts = $925
Required
Number of singles tickets sold.
Let S and C represent singles and couples respectively.
If the total number of tickets sold is 365, then
S + C = 365 --- (1)
Also, if the singles are charged $2 and couples, $3, then
2S + 3C = 925 ----- (2)
Make C the subject of formula in (1)
C = 365 - S
Substitute 365 - S for C in (2)
2S + 3(365 - S) = 925
Open bracket
2S + 1095 - 3S = 925
Collect like terms
2S - 3S = 925 - 1095
-S = -170
Multiply both sides by -1
-1 * -S = -1 * -170
S = 170
Recall that S represents number of single present at the even.
Hence, the number of singles are 170
