Answer:

Step-by-step explanation:

We have to check each one answer in the following system:

x - 2y = 7

13x + 7y = 8

a. (7,0)

7 - 2.0 = 7 (it's true)

13.7 + 7. 0 = 8 (it's false)

It isn't a correct answer.

b. (5, -1)

5 - 2.(-1) = 7 (correct)

13.5 + 7 (-1) = 8 (wrong)

It isn't a correct answer.

c. (-2,2)

-2 - 2.2 = 7 (wrong)

d. (3, -2)

3 - 2. (-2) = 7 (correct)

13.(3) + 7.(-2) = 8 (wrong)

So, none of them is answer.

The independent variable is what you manipulate in a study, whereas the dependent variable is what you measure.

Central tendency is another word for average.

L. - (6x - 5) = -6x +13

zzz [600]

Answer:

No Solution.

Step-by-step explanation:

-(6x-5)=-6x+13

-6x+5=-6x+13

-6x-(-6x)+5=13

-6x+6x+5=13

0+5=13

5=13

1st Picture:
$3)- \frac{6}{7} +\frac {10}{11}
\\\\LCD:77
\\\\\frac{6}{7}* \frac{11}{11} + \frac{10}{11}*\frac{7}{7}= \frac{66}{77} + \frac{70}{77} = \frac{136}{77} = 1\frac{59}{77} 
 \\ \\ 4) 3\frac{6}{7}* 2 \frac{1}{10}= \frac{27}{7} * \frac{21}{10} = \frac{567}{70} =\frac{81}{10} = 8\frac{1}{10}
\\\\5)2\frac{1}{2}+3\frac{1}{3}
\\\\LCD: 6
\\\\ 2\frac{3}{6} + 3\frac{2}{6} =5\frac{5}{6}
\\\\6)5\frac{1}{8}*-6\frac{6}{11}=\frac{41}{8}* \frac{72}{11}=\frac{2952}{88}=\frac{369}{11}=33\frac{6}{11}$

2nd Picture:

$1)80 percent of 80 = .8*80 =64
\\\boxed{64}
\\\\2)95percent of 100=.95*100=95
\\\boxed{95}$

Chinese checkers is a game in which players move their pieces across a board using single moves or jumps like the traditional ga

DENIUS [597]

A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)
