Answer : 4
Explanation : you minus the 2 on both sides bc they have the same "last name" by doing this you get 12 on the left and elimination 2 on the right which leaves you with 12=3x. Divide 3 on both sides which 12/3 =4 and ur left with x. So the final equation is 4=x
Alicia buys 4 scarves. She pays $75.20 plus an additional $5.26 in tax for the scarves
Total cost paid for 4 scarves = 75.20 + 5.26 = 80.46
to find cost of 1 scarve we divide the total cost by 4
Alicia determines that each scarf cost $20.12
We got the same cost . So Alicia's calculation is correct.
180 = 2x-10+x+30+70
180 = 3x+90
90 = 3x
x = 30
2(30)-10 =50
Answer:
Step-by-step explanation:
y=2x+1
y=x^2
The other one isn't a function because it won't pass the vertical line test. You can not use the same X in a function.
