-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest
Answer:
[tex] \sf z = - \dfrac{2}{3} [/tex]
Step-by-step explanation:
Solve for z:
[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)
-4(z + 2) = -4z - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8
Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8
-z - 4z = -5z:
[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8
Expand out terms of the left hand side:
[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8
Add 5z to both sides:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8
5z - 5z = 0:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8
5z - 2z = 3z:
[tex] \longrightarrow [/tex] 3z - 6 = -8
Add 6 to both sides:
[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8
6 - 6 = 0:
[tex] \longrightarrow [/tex] 3z = 6 - 8
6 - 8 = -2:
[tex] \longrightarrow [/tex] 3z = -2
Divide both sides of 3z = -2 by 3:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]
[tex] \sf \dfrac{3}{3} = 1 :[/tex]
[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]

There are many properties of exponents. These properties are used to make problems with exponents simpler.
Choose one of the properties and explain why it is true. Then write a numerical expression and use the property you chose to simplify the expression.
Answer:
Power of a Quotient.
explanation: The Power of a Quotient Rule states that the power of a quotient is equal to the quotient obtained when the numerator and denominator are each raised to the indicated power separately, before the division is performed.

Answer: 0.000021 in scientific notation is
2.1 × 10-5
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.000021 into scientific notation, follow these steps:
Move the decimal 5 times to right in the number so that the resulting number, m = 2.1, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -5
Write in the scientific notation form m × 10n
= 2.1 × 10-5
Therefore,
2.1 × 10-5 is the scientific notation form of 0.000021 number and 2.1e-5 is the scientific e-notation form for 0.000021
