Find 3 consecutive even integers such<br> that the sum of the first and third is -16.
ICE Princess25 [194]

Answer:

<em>1st number =</em> -10

<em>2nd number =</em> -8

<em>3rd number =</em> -6

Step-by-step explanation:

<em>Take the first number as x</em>

The next consecutive even number will be x+2

The 3rd even number will be x+4.

<em>Sum of 1st and 3rd number = -16</em>

(x) + (x+4) = -16

x+ x+4 = -16

2x + 4 = -16

2x = -16 -4

2x = -20

x = \frac{-20}{2}

x = -10

2nd number = x+ 2

                     = -10 + 2

                     = -8

3rd number = x + 4

                    = -10 + 4

                    = -6

<em></em>

<em>Hope this helps.</em>

Simplify the expression 10 to the 5th power times 10 to the 4th power
Brut [27]

Answer:

Step-by-step explanation:

In exponential form, those look like this:

10⁵ × 10⁴

Those 10's are not just regular numbers, they're called bases. The rule for multiplying bases with exponents is that if you're multiplying like bases, you add the exponents. We do indeed have like bases, so we add the exponents 5 and 4 together (which is 9) so the solution to this simplification is 10⁹. If the bases are not like, this rule does not apply. In fact, no rule applies!!
