Answer:
y=1/2x+1
Step-by-step explanation:
Answer: x = 13/5
Explanation:
(x+4)/(3x+1) = 3/4
Cross multiply:
4(x+4) = 3(3x+1)
4x + 16 = 9x + 3
4x - 9x = 3 - 16
-5x = -13
x = -13/-5
x = 13/5
Do answer this you need to multiply the amount by the decimal value of the percentage. To get the decimal of a percentage you divide the percentage by 100, so:
10 / 100 = 0.1,
Now you can multiply the weight by the decimal to find the 10% value:
64 * 0.1 = 6.4 pounds,
So 64 - 6.4 = 57.6 which is the decreased price.
The decreased amount is 57.6 pounds.
Hope this helps!
Answer: y = -2x + 8
