Ineed some with a few multiple choice math questions here's one:
the two-way table shows the number of students in a class who like mathematics and/or science.

like mathematics

do not like mathematics

total

like science

18

?

38

do not like science

16

6

32

total

34

26

70

what is the missing number in the table?
10
12
20
56

Which shows the first equation written in slope-intercept form? 1/2 (2y + 10) = 7x

Statement reason 1. δabc is similar to δced. given 2. 3. definition of slope 4. slope of slope of definition of slope 5. slope of × slope of multiplying the slopes 6. slope of × slope of substitution property of equality 7. slope of × slope of simplifying the right side the table contains the proof of the relationship between the slopes of two perpendicular lines. what is the reason for statement 2? a. parallel line segments that meet a common perpendicular line are proportional in length. b. the lengths of vertical and horizontal sides in congruent triangles are in a common ratio. c. trigonometric identities determine the lengths of the legs in a right triangle. d. corresponding side lengths in similar triangles are proportional in length.

Add. express your answer in simplest form. 12 9/10+2 2/3 = i need u guys to me find the answer to this question
