Answer: x= -2
Step-by-step explanation: use pemdas
10x + 8 = 3(x - 2) distribuite parenthesis
10x + 8 = 3x - 6
10x + 8 = 3x - 6 add like terms
7x +8= -6 add like terms
7x= -14 divide to get x alone
x= -2
Answer: 925 pages
Step-by-step explanation:
From the question, we are told that with a full ink cartridge, a printer can print 2,500 pages but that the printer cartridge is now 37% full.
The best estimate of the number of pages the printer can still print will be calculated as:
= 37% × 2500
= 0.37 × 2500
= 925 pages
Answer:
$127.45
Step-by-step explanation:
First, subtract 450 from 3,508.80:
3,508.80 - 450 = 3058.8
Then, divide this by 24 to find the monthly payment:
3058.8/24
= 127.45
So, the monthly payment was $127.45
Answer:
n = 24
Step-by-step explanation:
16+ n/4 =22
Subtract 16 from each side
16-16+ n/4 =22-16
n/4 = 6
Multiply each side by 4
n/4*4 = 6*4
n = 24
Answer:
sec²(x) - sec(x) + tan²(x) = (sec(x) - 1)(2sec(x) + 1)
Step-by-step explanation:
sec²(x) - sec(x) + tan²(x) =
= sec²(x) - sec(x) + [sec²(x) - 1]
= sec²(x) - sec(x) + [(sec(x) + 1)(sec(x) - 1)]
= sec(x)[sec(x) - 1] + [(sec(x) + 1)(sec(x) - 1)]
= (sec(x) - 1)(sec(x) + sec(x) + 1)
= (sec(x) - 1)(2sec(x) + 1)
