Answer:

5 =x

Step-by-step explanation:

X+2x+15=5x+5

Combine like terms

3x+15 = 5x+5

Subtract 3x from each side

3x+15 -3x = 5x+5 -3x

15 = 2x+5

Subtract 5 from each side

15-5 = 2x+5-5

10 =2x

Divide each side by 2

10/2 =2x/2

5 =x

Which inequality is equivalent to -m 2 15?

inysia [295]

The correct answer is option 3: m≤-15

Step-by-step explanation:

The inequalities are solved by performing operations on both sides of inequality

Given inequality is:

$-m\geq 15$

when an inequality is multiplied by -1 the signs of numbers on both sides are changed while the inequality operator is also reversed.

Multiplying both sides by -1 will give us:

$m\leq -15$

The correct answer is option 3: m≤-15

"At $1.29 million, they closed last month for...26 percent above what they paid in 2007." How much did they pay in 2007?

Morgarella [4.7K]

Answer: Amount that they paid in 2007 is 1.01 millions.

Step-by-step explanation:

Since we have given that

Number of millions paid last month = $1.29 millions

According to question, it was 26% above what they paid in 2007.

Let the amount paid in 2007 be x

So, our equation becomes,

$\frac{100+27}{100}\times x=1.29\\\\\frac{127}{100}\times x=1.29\\\\1.27\times x=1.29\\\\x=\frac{1.29}{1.27}\\\\x=1.01\ millions$

Hence, Amount that they paid in 2007 is 1.01 millions.
