4x + 10 = 2x - 14

Step 2: Solve for x

[Subtraction Property of Equality] Subtract 2x on both sides: 2x + 10 = -14
[Subtraction Property of Equality] Subtract 10 on both sides: 2x = -24
[Division Property of Equality] Divide 2 on both sides: x = -12

Answer:

x= -12

Step-by-step explanation:

Simplifying

4x + 10 = 2x + -14

Reorder the terms:

10 + 4x = 2x + -14

Reorder the terms:

10 + 4x = -14 + 2x

Solving

10 + 4x = -14 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

10 + 4x + -2x = -14 + 2x + -2x

Combine like terms: 4x + -2x = 2x

10 + 2x = -14 + 2x + -2x

Combine like terms: 2x + -2x = 0

10 + 2x = -14 + 0

10 + 2x = -14

Add '-10' to each side of the equation.

10 + -10 + 2x = -14 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = -14 + -10

2x = -14 + -10

Combine like terms: -14 + -10 = -24

2x = -24

Divide each side by '2'.

x = -12

Simplifying

x = -12

The mass of an electron is approximately 9.11 × 10 -28 grams. Find the mass of 401,000,000 electrons. 3.65311 × 10-19 grams 3.65

NNADVOKAT [17]

Answer:

$Total\ Mass = 3.65311 * 10^{-19}$ grams

Step-by-step explanation:

Given

$Mass = 9.11 * 10^{-28}g$

Required

Determine the mass of 401,000,000 electrons

To do this, we simply multiply the mass of 1 electron by the number of electrons.

This gives:

$Total\ Mass = 401,000,000 * 9.11 * 10^{-28}$

$Total\ Mass = 3653110000 * 10^{-28}$

Express 3653110000 as a standard form

$Total\ Mass = 3.65311 * 10^9 * 10^{-28}$

Apply law of indices:

$Total\ Mass = 3.65311 * 10^{9-28}$

$Total\ Mass = 3.65311 * 10^{-19}$

Hence, the mass of 401000000 electrons is $3.65311 * 10^{-19}\ grams$

A retired woman has $80,000 to invest but needs to make $6,000 a year from the interest to meet certain living expenses. One bon

Svetach [21]

The woman will have to invest 40000 at .15 to earn 6000 a year in interest. that leaves her 40000 to invest in a cd.

I set this up...

6000/x=15/100
cross multiply giving you 600000=15x
divide 600000 by 15 for x.
40000

40000 from 80000 leaves 40000 for investing
