-(7-2x) + 7 = -7 What is X?

Mathematics
1 answer:
Mekhanik [1.2K]2 years ago

Answer: x= -\frac{7}{2} = -3 \frac{1}{2} = -3.5

Step-by-step explanation:

−(7−2x)+7=−7

To find the opposite of 7−2x, find the opposite of each term.

−7−(−2x)+7=−7

The opposite of −2x is 2x.

−7+2x+7=−7

Add −7 and 7 to get 0.

2x=−7

Divide both sides by 2.

x = \frac{-7}{2}

Fraction  −7/2 can be rewritten as −2/7 by extracting the negative sign.

x = -\frac{7}{2}

As the exponent on the base 10 increases, does
trapecia [35]

Answer:

Since the exponent on 10 is positive, I know they are looking for a LARGE number, so I'll need to move the decimal point to the right, in order to make the number LARGER. Since the exponent on 10 is "12", I'll need to move the decimal point twelve places over.

First, I'll move the decimal point twelve places over. I make little loops when I count off the places, to keep track:

3.6 _ _ _ _ _ _ _ _ _ _ _ .

Then I fill in the loops with zeroes:

3.600000000000.

In other words, the number is 3,600,000,000,000, or 3.6 trillion
