Answer:

x = -10

x = 7

Step-by-step explanation:

2(x+3) = x - 4

2x + 6 = x - 4

2x -x = - 4 - 6

x = - 10

4(5x-2) = 2(9x+3)

20x - 8 = 18x +6

20x - 18x = 6 + 8

2x = 14

x = 7

have a nice day :D

2x(x + 3)= x - 4
2x + 6 = x - 4
2x - x - 4
X = -10

4(5x + -2) = 2(9x + 3)
20x - 8 = 18x + 6
20x -18x = 6 + 8
2x/2 = 14\2
X = 7

1) Diego measured the number of cups of water in 15 bottles of various sizes. He

Ivan

Answer:

$8\frac{3}{4}$ cups.

Step-by-step explanation:

From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).

If he poured all 5 of this bottle sizes in 1 container, he would have the following:

$1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4}$

$= 8\frac{3}{4}$ cups.

Which is greater, |-6.3| or |-19\20|

MrMuchimi

|6.3| because the lines mean absolute value. Take the positive number values of each number and compare them. 6.3 vs 19/20. 19/20 is 0.95 so 6.3 is bigger.
