Mathematics
1 answer:
vovangra [49]3 years ago
7 0

Answer:

1) -3x + 5 = -10

-3x = -15

x= -15/-3

X = 5

3) 4-6x = -8

-6x = -8-4

-6x = -12

X = 2

2) 2(x-5)= -5

2x - 10 = -5

2x = 5

x = 2.5

4) -0.5(2x+6) = -6

-x -3 = -6

-x = -6+3

-X = -3 ( both negative will get cancel)

X = 3

79,82,85,91,97,73,88,87,85,92,90,85,86,91,94,85,92
yKpoI14uk [10]

Hello!

First of all, we need to order the numbers least to greatest.

73,79,82,85,85,85,85,86,87,88,90,91,91,92,92,94,97

As there is an odd number, one of the numbers in our data set is the median. If we subtract this number, we would have 16. If we split that we have 8 on each side. So, to find the number in the middle, we find the 9th number.

If you count, you see that the middle number is 87.

Therefore, the median is B) 87.

I hope this helps!

I need help with this problem if anybody can help thank you
xxMikexx [17]
I think the answer is B. because the sum of the 2 smaller numbers is greater than the 3rd number.

a. 8+6 = 14 ; 14 is less than 16 ; wrong
b. 8+6 = 14 ; 14 is greater than 10 ; correct
c. 7+6 = 13 ; 13 is less than 14 ; wrong
d. 6+7 = 13 ; 13 is less than 20 ; correct

Hope this helped☺☺
