3x - 5 = 10 x = ______
Sphinxa [80]

Answer:

3x - 5 = 10 x

The answer is: x=-\frac{5}{7}

Step-by-step explanation:

3x - 5 = 10x

First, Please, Add 5 to both sides, Which would be:

3x - 5 + 5 = 10x + 5

Second, Please, Simplify your answer, Which would be:

3x = 10x + 5

Third, Please, Subtract 10x from both sides, Which would be:

3x - 5 = 10x = 10x + 5 - 10x

Forth, Please, Simplify your answer, Which would be:

-7x = 5

Fifth, Please, Divide both sides by -7, Which would be:

\frac{-7x}{-7}=\frac{5}{-7}

Last and Finally, Simplify your answer, Which would be:

x=-\frac{5}{7}

I hope I helped :)

34kurt

Answer: \$175

Step-by-step explanation:

Since Gloria cannot pay for each minute talked but for packages of 200 minutes at the rate of $25 each, we have to make calculations according to these conditions as follows:

Month 1:

Gloria talked on her cell phone for 320 min. So, she had to buy 2 packages of 200 min for \$25 each package.

Hence:

(\$25) 2= \$50

Month 2:

Gloria talked on her cell phone for 243 min. So, she had to buy again 2 packages of 200 min for \$25 each package.

Hence:

(\$25) 2= \$50

Month 3:

Gloria talked on her cell phone for 489 min. So, she had to buy 3 packages of 200 min for \$25 each package.

Hence:

(\$25) 3= \$75

Then, if we take the total Gloria had to pay for the frist three months, we have:

\$50 + \$50 + \$75= \$175

bearhunter [10]

Answer:x \in (\frac{5}{3},\frac{19}{3})

Step-by-step explanation:

Given

length of three sides are

3x, 7\ and\ 12

according to Euclidean geometry

7+12>3x

19>3x

\frac{19}{3}>x

also

3x+7>12

3x>5

x>\frac{5}{3}

therefore value of x \in (\frac{5}{3},\frac{19}{3})

If x is an integer then x can be 2,3,4,5,6
