Answer:
x-30y=100 and 10y=x-20
Step-by-step explanation:
Steps:
7w - 2 + w = 2(3w - 1)
6w - 2 = 6w - 2
Because both sides of the equation are equal, w = an infinite amount of solutions.
Have a great day!
Answer:
4 right; 4 up
Step-by-step explanation:
The difference between the two points is ...
P'(1, 5) -P(-3, 1) = (1-(-3), 5-1) = (4, 4)
The translation is 4 units to the right and 4 units up.
Food bill = $68.26
Tax rate = 7 %
Tax that will be payed = 7/100 × 68.26

Hope u get the answer
Answer:
The number sold at $12.50 is 25
The number sold at $9.50 is 62
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
x 12.50 + y 9.50=901.50
x+y= 87
Where
x= number of pottery pieces sold
y= number of pottery pieces sold at a decreased price
Multiplying the second equation by 9.50, and subtracting the second equation to the first equation:
12.50 x + 9.50y = 901.50
-
9.50 x+ 9.50 y= 826.5
__________________
3 x = 75
Solving for x
x =75/3
x = 25
Replacing x=25 on any equation:
x+y= 87
25+y =87
y=87-25
y= 62
