Answer: x=4, y=-2

Step-by-step explanation:

we can use the elimination method to eliminate one term to find x. Let multiply the top system by 4 then add the second system to eliminate the variable.

4(3x-y=14)

12x-4y=56

5x+4y=12

17x=68

x=4

Since we know x=4, let plug this back in to one of the system to find y.

5(4)+4y=12

20+4y=12

4y=-8

y=-2

  A triangular prism. The rectangular sides are 2.5 millimeters by 8 millimeters, 8 millimeters by 6.5 millimeters, and 8 millim
allsm [11]

Answer:

<u>The triangular prism shown has 2 triangular faces and 3 lateral faces.</u>

  • The triangles are on the ends, and there are three rectangular faces, which are the "lateral" faces because they're not bases.

<u>The area of one triangular face is 7.5 square millimeters.</u>

  • Area of triangle = 1/2 b*h = 1/2* 6*2.5 = 1/2*15 = <u>7.5 square millimeters</u>

<u>The surface area of the triangular prism is 135 square millimeters.</u>

  • Lateral face area = the sum of the three lateral faces. = 8*6.5 + 8*2.5 + 6*8 = 120 square millimeters
  • Surface area = 2(triangle area) + sum of lateral faces = 2(7.5) + 120 = <u>135 square millimeters</u>

Kyle soles 18 of 24 puzzles in a puzzle book. he says that he can use an equivalent fraction to find the percent of puzzles in t
tino4ka555 [31]

Answer:

He solved 75% of the puzzles!

Step-by-step explanation:

Okay, let's look at our fraction 18 out of 24. We can see that they are both even numbers, so at worst, we can divide the entire fraction by two. However, they have a GCF of six, so we will use that.

18                               3

----  divided by 6  =  ----

24                              4

Now that we have the fraction 3/4, we can turn that into a percentage!

3/4 is 0.75. To get the percentage, we multiply that by 100--now we have 75%.

Arsenic is toxic to humans, and people can be exposed to it through contaminated drinking water, food, dust, and soil. Scientist
andrezito [222]

Answer:

The mean, because the outlier values are above the mean.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is given by the sum of all values of the data-set divided by the number of values.

Median:

The median of a data-set is the value that separates the lower 50% from the upper 50% of the sorted set.

0.8, 1.9, 2.7, 3.4, 3.9, 7.1, 11.9, 26.0

Finding the median, since it is easier.

8 values, the median is the mean between the 4th and the 5th values. (3.4+3.9)/2 = 3.65

The values below the median are quite close to it, while those above it are considerably more distant, considered outliers, which means that we should expect the mean to be larger than the median.
