Answer:
x=0
y=6
Step-by-step explanation:
3y- 12x = 18
2y-8x= 12
rearrange the equation
2y-8x=12
add 8x to both sides
2y=8x+12
divide both sides by 2
y=4x+6
now substitute it into 3y-12x=18
3(4x+6)-12x=18
simplify
12x+18-12x=18
simplify
18=18
x=0
substitute to find y
2y-8(0)=12
2y=12
y=6
Recheck:
3(6)-12(0)=18
18=18
2(6)-8(0)=12
12=12
Answer:
Multiply the first bracket by 3
Multiply the second bracket by -2
3x+3=-2x+2-4
3x+2x+3=-2x-2 negative (-) number and positive number (+)= negative number
Just rearranging
5x+3=-2
5x+3-3=-2-3
5x=-5
Dividing by 5
5x/5=-5/5
x=-1
Check answer by using substitution method
3(-1+1)=-2(-1-1)-4
0=-2(-2)-4 negative number and negative number = positive number
0=4-4
0=0
Answer is x=-1
2 minutes = 1.20 dollars for price of sundae.in 4 hours how many minutes are there?=> 60 * 4 hours = 240 minutes => 240 / 2minutes per sundae = 120 minutes => 120 * 1.20 = 144 dollars in 4 hoursOr 72 dollars in 2 hours

Answer: 792
Step-by-step explanation:
From what I got it should be 792 because it is asking for doubles, triples, and home runs all together at the same amount that he got on his first year.
It says after 12 years
Doubles 47 times 12 years = 564
Triples 4 times 12 years = 48
and
Home runs 15 times 12 years = 180
564 + 48 = 612
612 + 180 = 792
