Answer:
1. $33.00
2. $48.00
3. $3.00
4. $36.40
Step-by-step explanation:
44.00 - 25% = 33 —> $33.00
80.00 - 40% = 48 —> $48.00
9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00
52.00 - 30% = 36.4 —> $36.40

Answer:
(2,-1)
y= -1
x= 2
Step-by-step explanation:
y= -2x+3
4x-3y=11
substitute the value of y into an equation
4x-3(-2x+3)=11
distribute by multiplying numbers in parenthesis by -3
4x+6x-9=11
add 4x to 6x
10x-9=11
add 9 from both sides
10x=20
divide both sides by 10
x=2
substitute the value of x into an equation
y= -2•2+3
multiply -2 to 2
y= -4+3
add -4 to 3 but 4 is negative, so subtract
y= -1

A. 8/$12=21/$x then cross multiply.
B. 1/$1.5
Answer:
x=4
Step-by-step explanation:
Let he first piece be x the second be 3x and the very last one be 7x + 2
Add all the pieces together and you ought to get the length of the rope which is 46 ft
So your equation would be
x + 3x + 7x + 2 = 46
11x = 44
x = 44 / 11
x = 4
so the 3 pieces are 4 , 12 and 30ft
