Solve 2(x + 1) = 2x + 5

no solution

Step-by-step explanation:

Given

2(x + 1) = 2x + 5 ← distribute parenthesis on left side

2x + 1 = 2x + 5 ( subtract 1 from both sides )

2x = 2x + 4 ( subtract 2x from both sides )

0 = 4 ← not possible

This indicates the equation has no solution

See below

Step-by-step explanation:

● 2(x+1) = 2x +5

Multiply 2 by (x+1)

● 2x + 1×2 = 2x+5

● 2x + 2 = 2x+5

Substract 2x from both sides

● 2x+2-2x = 2x+5-2x

● 2 = 5

This is impossible, so this equation has no solution.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
