Answer:
(x, y ) = (- 2, 3 )
Step-by-step explanation:
given the 2 equations
7x - 2y = - 20 → (1)
9x + 4y = - 6 → (2)
multiply (1) by 2 making the coefficients of y equal and opposite
14x - 4y = - 40 → (3)
add (2) and (3) term by term
(9x + 14x ) + (4y - 4y ) = (- 6 - 40 )
23x = - 46 ( divide both sides by 23 )
x = - 2
substitute x = - 2 into either (1) or (2) for y
(2) - 18 + 4y = - 6 ( add 18 to both sides )
4y = 12 ( divide both sides by 4 )
y = 3
solution is (- 2, 3 )
Answer:
$4.64
Step-by-step explanation:
1 cup = 16 tablespoons
cup = 8 tablespoons
Each lemon yields about 2 tablespoons of juice. You need 8 tablespoons for one lemon pie, so you need
lemons for one pie and
lemons for two pies.
The store is selling lemons at $0.58 each, hence, 8 lemons will cost

Answer:
w = 15
Step-by-step explanation:
-9(w + 585) = -360w
-9w -5265 = -360w
351w = 5265
w=15
The number expressed as a decimal is 0.36
Step-by-step explanation:
First of all, we have to write the ratio between the number of songs from Josiah's favorite band and the total number of songs.
We have:
# of songs of his favorite band = 16
# of total songs = 44
Therefore, the fraction is:

Now we have to express this as a decimal. First of all, we simplify the fraction, by dividing each number by 4, and we get:

Now in order to write this as a decimal, we just use the calculator and we divide 4 by 11, and we get:

which is a periodic number, so we approximate to
