Help me with this math question please! And im giving

Ok, got it. The answer is 1/10.

Step-by-step explanation:

It helps a lot if you write out what they give you; in this case:

Ten million is what is known as a "place value". This is just a word that describes where an individual digit, or number, is placed within a bigger number. A few examples:

For your question, I'm going to write it out, same deal: 8 x 10 = 80, since they ask for the value of the 8, and it is in the 10 millions place. So our first number is 80 million, or 80,000,000. (You can count each zero as a "place", from right to left: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions)

It's the same for the second part: 8 x 100 = 800, since they ask for the value of the 8, but this time in the 100 millions place. 800 million, or 800,000,000. The only difference, as the problem says, is that this 8 is in the hundred millions place.

The answer comes from asking: 80,000,000 divided by 800,000,000 is what? 80,000,000/800,000,000 = 0.1, which is the same thing as saying one-tenth.

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
