What is 500 rounded to the nearest hundred

rosijanka [135]

Answer: 500

Step-by-step explanation:

The reason why it's 500 because it's already been rounded. 500 stays as 500 bc numbers 4 and below goes down to 0 when rounding. When rounding 0-4 with just the ones place it stays the same.

What is the solution of the following system of linear equations? −21 + 15x = 6y −5x + 2y = −8 Select one: A. (15, -7) B. (4, 11

quester [9]

Answer:

C. No solution

Step-by-step explanation:

System of Equations:

A) $-21+15x=6y$

B) $-5x+2y=-8$

Simplifying and rearranging equation A.

Dividing each term by 3 (common factor for each term) in equation A.

$\frac{-21}{3}+\frac{15x}{3}=\frac{6y}{2}$

$-7+5x=2y$

Subtracting both sides by $2y$

$-7+5x-2y=2y-2y$

$-7+5x-2y=0$

Adding 7 both sides.

$-7+7+5x-2y=0+7$

$5x-2y=7$

Adding the above equation to equation B.

$5x-2y=7$

+ $-5x+2y=-8$

We have $0=-1$

which is not true.

Hence the system has no solution. (Answer)

Help is number 2 correct and help for number one

gayaneshka [121]

Number 2 is incorrect :

$\frac{-25x^{3}+15x }{5x} = \frac{-25x^{3}}{5x} + \frac{15x}{5x} = -5x^{2} + 3$

Number 1 :

$(-5)^{3} . 13^{-2} . (-5) .13^{9} = -125 . \frac{1}{13^{2}} .(-5).13^{9} = 625 . \frac{13^{9}}{13^{2}} = 625 . 13^{7}$ (i dont think we can bare calculate this cause it;s too big ;-;)
