Call T the price of the T-shirts and P de price of the jeans
Initially (without discount)
2T + P = 40
One month later (half prices)
2 (T/2) + 5(P/2) = 60
T +5P/2 = 60
To solve the system of equations multiply the second equation by 2 and substract it from the first equation
2 T + 5P = 120
- (2 T + P = 40 )
________________
4P = 80
P = 80/4
P = 20
From 2T + P = 40
T = (40 - P) / 2 = (40 -20) / 2 = 20/2 = 10.
The price of a T-shirt is $10 and the price of a pair of jeans is $20.
Answer:
You will never be able to reach the sum of 2
Step-by-step explanation:
PRQ and QRS should add to PRS
(3x-8)+(2x+6)=98
5x-2=98
5x=100
x=20
Plug 20 into both expressions:
3(20)-8
60-8
52 degrees= PRQ. <===========
2(20)+6
40+6
46 degrees= QRS. <==========
Answer:
11
Step-by-step explanation:
f(1) = 3(1) + 8 = 3 + 8 = 11
To take a root of a fraction, take the root of the numerator and denominator separately
Write the number in exponential form with a base of 2 to the second power
Write the number in exponential form with a base of 3 to the third power
Reduce the index of the radical and exponent with2
Reduce the index of the radical and exponent with 2
Then it’s gonna be 2/3 2over3
-3 2/3
Reduce the numbers with greatest common divisor 3
Then the answer will be -2
