How to estimate 96 Times 34 what is the answer
Marrrta [24]

When it says to estimate, I always think of doing it by hand to show work.  So set it up like this:

  96

<u>x 34</u>

So follow it out multiplying across 4*6 and 4*9 carrying over as needed to get it to look like this:

  96

<u>x 34</u>

384


Do the same for the 3 to get this:

  96

<u>x 34</u>

  384

2880

Add 384+2880=3264

Your final answer is 3,264

How many solutions does the following equation have?
RoseWind [281]

Answer:

There will be No solution for the equation 9x - 4 = - 3x + 5 + 12x. Option B is correct.

Step-by-step explanation:

We need to determine how many solutions the equation 9x - 4 = - 3x + 5 + 12x have.

Solving the equation and finding the solutions

9x - 4 = - 3x + 5 + 12x

Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.

9x +3x-12x =  5 + 4

Simplifying

12x-12x =  9\\0=9

Solving the equation we get 0=9 which is false. So, there will be No solution for the equation 9x - 4 = - 3x + 5 + 12x. Option B is correct.
