For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x
Now multiply 7*2= 14
14 = 9 + x
Now subtract 9 from both sides to isolate the x
5 = x or x= 5
5 x 40 = 200 it will take her 200 days to wear each shirt
<span>a. What is the probability that the printer produces more than 12,000 pages before this cartridge must be replaced?
solution
to solve the equation we need to find the z-score:
z=(x-</span>μ)/σ
where:
x=12000
μ=mean=11500
σ=standard deviation=800
thus
z=(12000-11500)/800=0.625
thus
P(x>12000)=1-P(x<12000)=1-0.7357=0.2643
<span>b. What is the probability that the printer produces fewer than 10,000 pages?
z=(10000-11500)/800
z=-1.875
hence
P(x<10000)
=0.0301

Answer:
infinite solution/all real numbers
Step-by-step explanation:
x+6+5x=6(x+1)
Step 1: Simplify both sides of the equation.
x+6+5x=6(x+1)
x+6+5x=(6)(x)+(6)(1)(Distribute)
x+6+5x=6x+6
(x+5x)+(6)=6x+6(Combine Like Terms)
6x+6=6x+6
6x+6=6x+6
Step 2: Subtract 6x from both sides.
6x+6−6x=6x+6−6x
6=6
Step 3: Subtract 6 from both sides.
6−6=6−6
0=0
so it is infinite solution/all real numbers
