If you factor it you will get:
(z+ 1)(x + y)
Answer:
The two numbers are 28 and 7.
Step-by-step explanation:
Let the first number be x
Let the second number be y
The difference of x and y is x-y=21
The quotient of two numbers is x/y = 4
x-y =21 (This is equation 1)
x/y=4 (This is equation 2)
By solving equation 2 we will get the value of x.
x/y=4
x=4y (Lets call it equation 3)
Now, put the value of x(equation 3) in (equation 1)
x-y=21
4y-y=21
3y=21
y=21/3
y=7
Now put the value of y in equation 3 to get the value of x
x=4y
x=4(7)
x=28
Solution Set {(x,y)(28,7)}
Answer:
Question 1: how much more does 1 1/4 pounds of beef cost than 1 1/4 pounds of turkey?
$4.25/pound (beef) / 4 = $1.06 per 1/4 lb = $4.25 + $1.06 = $5.31 per 1 1/4 lb
$2.85/pound (turkey) / 4 = $0.71 per 1/4 lb = $2.85 + $0.71 = $3.56 per 1 1/4 lb
$5.31 - $3.56 = $1.75 the beef is more expensive by this much compared to the 1 1/4 lb of turkey
Question 2: question 2. brad has 10 dollars to spend at ruby's. He orders 1/2 pound of sausage and 1 1/4 pounds of chicken. How much money will he brad have after he pays for this order?
$3.25 / 2 = $1.62 per 1/2 pound of sausage
$2.50 / 4 = $0.62 per 1/4 lb of chicken + $2.50 = $3.13 per 1 1/4 lb of chicken
$1.62 (1/2 lb sausage) + $3.13 (1 1/4 lb chicken) =$4.75
$10 (budget) - $4.75 (total expense) = $5.25 Brad will have this left
