What is 6.9 × 107 written in standard form?
mihalych1998 [28]
6.9 x 10⁷ is a scientific notation.

6.9 x 10⁷ in standard form is 69,000,000

Scientific notation is used to represent very large numbers or very small numbers.

Scientific notation has three parts. Its parts are the coefficient, base of ten, and the exponents.

6.9 is the coefficient
10 is the base of 10
7 is the exponent

The must always be 1 digit before the decimal point in the scientific notation.
The exponent tells us the number of places the decimal point has moved. Its sign tells us the direction of the decimal point's movement.

Since the exponent is positive, it tells us that the decimal point moved from right to left.

69000000. to 6.9000000

If the exponent had a negative sign, it means that the decimal point moved from left to right.

example: 6.9 x 10⁻⁷
its standard form would have been .00000069

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6
loris [4]

Answer:

x = \frac{86}{179}

Step-by-step explanation:

7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6

Multiply both sides by 10:

7.4x×10+4.1(2x-4)×10=-2.3(x-6)×10-21.6×10

Refine:

74x+41(2x-4)=-23(x-6)-216

Distributive Property:

74x+82x-164=-23(x-6)-216

Combine like terms:

156x-164=-23(x-6)-216

Distributive Property:

156x-164=-23x+138-216

Combine like terms:

156x-164=-23x-78

Add 164 to both sides:

156x-164+164=-23x-78+164

Simplify:

156x=-23x+86

Add 23x to both sides:

156x+23x=-23x+86+23x

Simplify:

179x=86

Divide both sides by 179:

\frac{179x}{179}=\frac{86}{179}

Simplify:

x = \frac{86}{179}
