Can you help me?

Answer 1

Hey there! :D

3. m • 5 = 125

To solve this problem, simply divide the quotient and the divisor of the given equation.

$125 ÷ 5 = \boxed{\sf 25}$

Checking:

To check, simply substitute the conclusion on the unknown quantity.

25 (m) • 5 = 125

Thus, the equation was correct which gives us the answer that:

$\large\boxed{ \sf \: m \: = \: 25}$

$\begin{gathered} \\ \end{gathered}$

4. 99 = a ÷ 6

To solve this problem, we need to amend the given division as a fraction.

$\sf 9 = \displaystyle \sf \: \frac{1}{6}$

Then, we'll have to multiply both aspects of the equation by 6 to get the value of a.

Thus, the value of a is 594.

$\large\boxed{ \sf \: a = 594}$

$\begin{gathered} \\ \end{gathered}$

5. 2x + 12 = 102

To get the value of x, simply first move the constant 12 to the right side of the equation and change its symbol.

2x = 102 - 12

Then, subtract the 102 from constant 12 whose value has been stridden.

2x = 90

Lastly, divide 90 by 2

Thus, the value of x is 45, and no more simplification can be done.

$\large \boxed{ \sf \: x = 45}$

Answer 2

Answer:

Below

Step-by-step explanation:

3. m5 = 125

   5m = 125

Divide both sides by 5

      m = 25

4. 99 = a / 6

   99 = 1/6a

   594 = a

5. 2x + 12 = 102

   2x = 102 - 12

   2x = 90

      x = 45

Hope this helps! Best of luck <3
