3. 1/15

explanation:
-3/5 and -2/3 need the same denominator so multiply them so that they equal the same. so multiply -3/5 by 3 and then -2/3 by 5. so that equals: -9/15 -(-10/15). The minis a negative cancels out and it becomes plus. so -9 plus 10 is 1 and 15 stays the same. so 1/15.

4. -5.2

explanation:
a negative (-2.5) subtracted by a technically smaller negative (-5.2) will equal a positive number

5.B

i just used a calculator tbh

Which description best fits the distribution of the data shown in the histogram?

s344n2d4d5 [400]

This is an approximately bell-shaped distribution. The highest bar is in the center, with height = 12. Just to its left and right are bars of heights 6 and 5. At the extremes are bars of heights 2 and 1.

If the highest bar was on the left, it would be skewed left (and if it was on the right, skewed right). A uniform distribution would more or less have the same height level over all the bars.

Solutions of 3x+2y=4 and 6x+4y=8

Alecsey [184]

Answer:

Infinite solutions

Step-by-step explanation:

1) First, you can solve this easily by elimination. Multiply the first equation by -2 in order to cancel out terms when adding to the second equation.

2) Then, add the new set of equations together. However, everything cancels out, bringing us to 0 = 0. This means that the lines the equations make must be the same. Thus, all real numbers must make this equation true, meaning that there are infinite solutions.
