Answer:

\huge\boxed{m=-4}

Step-by-step explanation:

\text{The distributive property:}\ a(b+c)=ab+ac\\\\-4(m+6)=-8\\\\(-4)(m)+(-4)(6)=-8\\\\-4m-24=-8\qquad\text{add 24 to both sides}\\\\-4m-24+24=-8+24\\\\-4m=16\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4m}{-4}=\dfrac{16}{-4}\\\\\boxed{m=-4}

There are 100 sheets of paper in the printer, and the number of sheets of paper, p, left after ,t, minutes of printing is given
zalisa [80]
P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use  all 100 sheets of paper;
Therefore;
if p(t)=0
Then:


-8t+100=0

We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5

Answer: the printer prints 100 sheets of paper in 12.5 minutes.

The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. A basic solution has a
Romashka-Z-Leto [24]

Answer:

0.003981 . . . . moles per liter

Step-by-step explanation:

The concentration of H+ ions in the acid will be ...

10^(-2.4) ≈ 0.003981 . . . . moles per liter

The concentration of H+ ions in the base will be ...

10^-11.2 ≈ 0.000 000 000 006310 . . . . moles per liter

To a few decimal places, the difference is ...

0.003981 . . . . moles per liter

_____

The two numbers differ by about 9 orders of magnitude, so the value of the difference between the larger and the smaller is essentially the value of the larger number. The smaller one, by comparison, can be considered to be zero (for subtraction purposes).

A student solved z + (-0.72) = -2.5 for z using the following steps.
prisoha [69]

The student's error was in first step where he added -0.72 instead of 0.72

Step-by-step explanation:

Given equation;

z + (-0.72) = -2.5

When solving for z, eliminate the other numbers from one side.

Step 1: z + (−0.72) + (−0.72) = −2.5 + (−0.72)

In this step, the student should have added 0.72 because -0.72 was already present in the equation and to eliminate it, he should have add same number with opposite sign.

According to this Step, -0.72 and -0.72 would have been added, because according to mathematics, two numbers with minus sign are added and the sign remains same.

The student's error was in first step where he added -0.72 instead of 0.72
