Let the number x.
Then the number divided by 2 gives

Subtract 3.8 from the quotient gives

Hence,


x = 21.6

When you're multiplying by a power of 10 such as 100, the decimal point moves two places to the right. Note that this corresponds with the number of zeroes in 100. Of course our number is going to get bigger, not smaller, which means we'd have to be going right. If we multiplied by something like 0.001, we'd also be going two places, just going smaller and to the left.
The answer is C and D
First we must make one side of the equation zero, so we subtract 7 on both sides of the equation, making the equation <span>9x^2 - 6x - 6 = 0
Then we will use the quadratic formula to find the answers.
</span>using the Quadratic Formula where:
a = 9, b = -6, and c = -6
and the formula is 6 +-

/ 2(9)
Answer:
−5xy^2+y^3+25x^2−5xy−y^2
Step-by-step explanation:
25x^2−5xy−5xy^2+y^3−y^2=
25x^2−5xy−2
———————————-
The answer is 8% because each rate (2%) goes up $200, making $1200 at 6% into $1800 at 8%.
Hope this helps!
