Q1: D
Q2: 45 minutes
Q3: 40.50
Q4: x=28, y=32
Answer:
The answer is a(7x+9)
Step-by-step explanation:
Answer:
y = -1/2x
Step-by-step explanation:
The slope is negative and 1/2, and y-intercept is 0
Let x = new apple price
Let y = $0.75 additional price
Let z = original price
3 pounds = apple Sam bought
$5.88 = total amount of apples Sam bought
1st, let
us divide 3 pounds from $5.88
5.88 ÷ 3 = 1.96 this
is the new apple price per pound.
X = $1.96
2nd, if you want to find the original price of
the apples per pound before the increase, we just need to subtract the X to Y.
$1.96 –$ 0.75 = $1.21 is the original price of apple before the increase.
I am assuming that it only 3 pounds of apples, since it will
be a negative / void if it will be 333 pounds, or even 33 pounds.
