Step-by-step explanation:
13.5 cents = 1 ounce
24 ounce= 13.5x24
Answer:
A. Two solutions
Step-by-step explanation:
y=6x−1
4x+4=6x−1
4x+4+−6x=6x−1+−6x(Add -6x to both sides)
−2x+4=−1
−2x+4+−4=−1+−4(Add -4 to both sides)
−2x=−5
−2x
−2
=
−5
−2
(Divide both sides by -2)
x=
5
2
Step: Substitute
5
2
for x in y=4x+4:
y=4x+4
y=4(
5
2
)+4
y=14(Simplify both sides of the equation)
Xy - the number
A) y -x = 7
B) (10x + y + 26) = 5 (x + y)
B) 10x +y + 26 = 5x +5y
B) 5x -4y = -26
multiplying equation A) by 4
A) 4y -4x = 28 Adding this to equation B
B) 5x -4y = -26
x = 2
y = 9
The number is 29
