16 or 8 what i did was multiplied it by .5
Answer:
(x, y) = (- 3, - 2)
Step-by-step explanation:
given the 2 equations
5x + 7y = - 29 → (1)
y = x + 1 → (2)
substitute y = x + 1 into (1)
5x + 7(x + 1) = - 29 ( distribute and simplify left side )
5x + 7x + 7 = - 29
12x + 7 = - 29 ( subtract 7 from both sides )
12x = - 36 ( divide both sides by 12 )
x = - 3
substitute x = - 3 into (2)
y = - 3 + 1 = - 2
solution is (- 3, - 2 )

Answer:
Its simple.
Step-by-step explanation:
Add Jerome to the 78 and then 1/4 of molly to get your answer.
bearing in mind that a whole is simply same/same or just 1.
3 dozen, there are 3 dozens in 3 dozen, obviously
dozen dozen dozen.
in 2 dozens, there are 2 of course
dozen dozen.
if 3 dozens is three thirds namely 3/3 = 1 = whole, then 2 dozens is just two of those dozens, namely two thirds, 2/3.
so if we use that many ingredients to make a whole three thirds, how much will it be to make only two thirds of it? well, is simply their product, so we'll simply multiply each ingredient amount by 2/3.
