Answer:
2x+1, if you want it just simplified
Step-by-step explanation:
3x-4-x+5 (distribute the negative)
2x+1 (combine like terms)
Step-by-step explanation:
draw it through the center to form the simplest line if that helps :)
For this case what you should do is solve the problem using for example a rule of three
60% ---> 36
100% ---> x
Clearing x we have:
x = (100/60) * (36) = $ 60
Checking the result:
40% of 60 is
(0.40) * (60) = 24
60-24 = 36 $
Answer:
the original price of the pair of headphones is $ 60
Answer:
17
Step-by-step explanation:
Using Triangle Midsegment theorem, it states that if :
Q is the midpoint of MN and R is the midpoint of NP
Then, QR is parallel to MP and QR = 1/2 of MP
Mathematically
QR = 1/2MP
From the above question, we are given the following values:
QR = 3x - 4
MP = 55 - 3x
Since
QR = 1/2MP
3x - 4 = 1/2(55 - 3x)
3x - 4 = 55/2 - 3x/2
Collect like terms
3x + 3x/ 2 = 55/2 + 4
9x/ 2 = 31.5
Cross Multiply
9x = 31.5 × 2
9x = 63
x = 63/9
x = 7
Since QR = 3x - 4
x = 7
QR = 3×7 - 4
= 21 - 4
= 17
Hence, QR = 17
