On a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions. the test is worth a total of 100 points. there are twice as many 2-point questions as 5-point questions on the test. how many 2-point questions are on the test?

8 Points

Step-by-step explanation:

Step one-Calculate how many 2 point answers and 5 point answers there are.

2 x 8 = 16

Since there are half as many 5 point answers as there are 2 point answers,

5 x 4 = 20

Next calculate how many remaining questions there are. The numbers would be 8 since you had 8 2 point questions and 4 since half of 8 is four.

8 + 4 = 12

Subtract that number by the total questions, being 28.

28 - 12 = 16

Next figure out how many 4 point questions you had (28-12=16)

16 x 4 = 64

To check your work simply add up the totals and see if they match up to the given amount of points (100).

16 + 20 + 64 = 100

So the answer is simply 8-four point questions.

80%

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
