Answer:
1. (4)x + y =50
2x + 4y =172
2. (1)x + y =8

Answer:
(x+12)
Step-by-step explanation:
The middle number is 8 and the last number is -48.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 8
Multiply together to get -48
Can you think of the two numbers?
Try -4 and 12:
-4+12 = 8
-4*12 = -48
Fill in the blanks in
(x+_)(x+_)
with -4 and 12 to get...
(x-4)(x+12)
But, since (x-4) isn't an option, the answer would be (x+12)
Answer:
Kelly is wrong and the recipe will make 19 cups of punch.
Step-by-step explanation:
It says:
The amount of ingredients in the recipe of punch after converting the units to 'cups' are given by,
Pineapple juice = 3 pints = 6 cups (1 pint ≈ 2 cups)
Orange juice = 5 cups
Lemonade = 1/4 gallon = 4 cups (1 gallon = 16 cups)
Apricot nectar = 1 quart = 4 cups(1 quart = 4 cups)
Then, the total cups of punch = 6 + 5 + 4 + 4 = 19 cups.
Thus, Kelly is wrong and the recipe will make 19 cups of punch.
