Answer:
a) x = -6
Step-by-step explanation:
5x - 14 = 8x + 4
-14 = 3x + 4
-18 = 3x
x = -6
Answer:
50 A and 50 B
Step-by-step explanation:
A》20
B》10
A + B》100 (for pants)
A + 3B》200 (for shirts)
A = 20
A + 3B = 200
3B = 180
B = 60
(20,60)
B = 10
A + B = 100
A = 90
(90,10)
A + B = 100
A = 100 - B
A + 3B = 200
100 - B + 3B = 200
2B = 100
B = 50
A = 100 - 50 = 50
(50,50)
Revenue:
30A + 50B
(20,10): 30(20) + 50(20)
= 1,100
(20, 60): 30(20) + 50(60)
= 3,600
(90,10): 30(90) + 50(10)
= 3,200
(50,50): 30(50) + 50(50)
= 4,000
Answer:
The correct option is B:
Subtract 2 from both sides
Step-by-step explanation:
We have the equation x²-4x+16=2
The first step to solve this equation is:
Subtract 2 from both sides
We get;
x²-4x+16=2
x²-4x+16-2=2-2
x²-4x+14=0
Now this is the quadratic equation. You can use quadratic formula to solve this equation....
18.75 because all sides of a square are equal so 75/4=18.75
