Answer:

25.9

Step-by-step explanation:

12+7x−(1−3) (evaluate parentheses first)

= 12+ 7x - (-2)

= 12+ 7x + 2

= 14+ 7x

When x = 1.7, equation becomes

14+ 7(1.7)

= 14 + 11.9

= 25.9

soldier1979 [14.2K]

Answer:

2x + 7 = 3x - 7

3x - 2x = 7 + 7

x = 14

2x + 7 + 12y + 1 = 180

2(14) + 12y + 8 = 180

28 + 12y + 8 = 180

36 + 12y = 180

12y = 180 - 36 = 144

y = 144/12 = 12

x = 14, y = 12

Three boxes of supplies have an average (arithmetic mean) weight of 7 kilograms and a median weight of 9 kilograms. What is the
GuDViN [60]

Answer:

3

Step-by-step explanation:

A) 1

(B) 2

(C) 3

(D) 4

(E) 5

Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of numbers / number of observation

sum of numbers = 3 x 7 = 21

Median is the number that is at the center or middle of a set of obervations

x +  9+ y = 21

x= lowest number

y = highest number

x + y = 21 - 9

x + y = 12

If x = 1 y = 11

if x = 2 y = 10

if x = 3 y = 9

if x = 4 y = 8

the first 3 are plausible and the median would still be 9 if x = 4, median would be 8
