Answer:
Step-by-step explanation:
1. Symbolically, we get: 62 - 5x < 40
2. y - 7.3 < 3.4. Solve for y by adding 7.3 to both sides, obtaining:
y < 10.7 This is both the 'range' and the 'solution'
3a) 4b = 9b + 45, or -5b = 45, or b = -9
3b) 5a + 10 = 4a - 4
Combining like terms results in a = -14
now.. hmmm -8/15 is rather ambiguous, since the negative sign is in front of the rational, and either 8 or 15 can be negative, now, we happen to choose the 8 to get the minus, but it could have been 8/-15
ok, well hmm so, the issue boils down to
now, let's take a peek at the second angle, angle β
now, with that in mind, let's use the angle sum identity for cosine

Answer:
The expression 40X represent the number of pages she read during X nights.
Step-by-step explanation:
Given : Tatiana read 40 pages of her book every single night
Let Tatiana read for X number of nights.
We have to write an expression that represent the number of pages she read during X nights.
The number of pages she read during X nights = number of pages Tatiana read every night × number of nights she spend
The number of pages she read during X nights = 40X
Thus, The expression 40X represent the number of pages she read during X nights.
