Complete question :
Gary has (20x + 7) dollars. Gary decides to buy two pairs of jeans. Each pair of jeans costs (2x - 3) dollars. write an expression that represents how much money gary will have left over after the purchase then simplify your expression
Answer:
$(16x - 1)
Step-by-step explanation:
Given that:
Amount Gary has = $(20x + 7)
Price per pair of jeans = $(2x - 3)
Number of pairs = 2
Cost of 2 Jean pairs = 2 * $(2x - 3) = $(4x - 6)
Amount left after purchase :
$(20x - 7) - $(4x - 6)
20x - 7 - 4x + 6
20x - 4x - 7 + 6
$(16x - 1)
I believe 1 is 3.8, b/c 1.9*2 is 3.8, and the difference between exponents makes 3 zeros, so 2000.
The second one is 40, I confirmed this by doing .0001 to replicate 10 to the negative 4th power
By doing 9.5*.0001*40, I got the 0.038 from 1
Answer:
x=4
Step-by-step explanation:
Sum means add
5+9x = 41
Subtract 5 from each side
5-5 +9x = 41-5
9x = 36
Divide each side by 9
9x/9 = 36/9
x = 4
