A reasonable estimate for 697 times 82 is

1 answer:

8 0

We could round both numbers to make estimation easier. So let’s say 82 is 80 and 697 is 700. If we know that 8 x 7 is 56, then 80 x 700 would just be 56,000. This is a great way to find estimates of big numbers.

If P is between L and A, PL = 6x + 24, PA = 12x - 6 and LA = 30x - 18, then x = ______ and LA = ___&&

To solve this problem, we have to use the definition of segment addition.

$LA=PL+PA$

Then, we replace the given expressions

$30x-18=6x+24+12x-6$

Now, we solve for <em>x</em>.

$\begin{gathered} 30x-6x-12x=24-6+18 \\ 12x=36 \\ x=\frac{36}{12} \\ x=3 \end{gathered}$ <h2>Hence, x = 3.</h2>

Let's find LA:

$30x-18=30\cdot3-18=90-18=72$ <h2>Hence, LA measures 72 units.</h2>
