Solve 5.4 = n/-0.9<br><br> Answers:<br> a. -4.86<br> b. -48.6<br> c. 48.6<br> d. 4.86
ZanzabumX [31]

Answer: 4.86

Step-by-step explanation: Since <em>n</em> is being divide by 0.9, to get <em>n</em> by itself, we need to multiply by 0.9 on both sides of the equation.

On the right side of the equation, the 0.9's cancel and we have <em>n</em>. On the left side of the equation, we have 0.9 × 5.4 which is 4.86.

Therefore, 4.86 = n.

What is (6*9)3+9-5 pls help me
marishachu [46]

By order of operations, you compute the value of the expression in the parentheses first:

6 * 9 = 54

Next, do multiplication:

54 * 3 = 162

Then, do addition and subtraction:

162 + 9 = 171

171 - 5 = 166

The answer is 166.
