Step by step explanation

a. no

b. yes

c. yes

d. no

Step-by-step explanation:

a. 2(20)+6=34 multiply 2 by 20

40+6=34 add 40 and 6

b. 27/3-2=7 divide 27 by 3

9-2=7 subtract

7=7

c. 23=3+4(5) multiply 4 and 5

23=3+20 add 3 and 20

23=23

d. 9=24/3-1 divide 24 by 3

9=8-1 subtract 8 and 1

a) the given value is not a solution to the equation

b) the given value is a solution to the equation

c) the given value is a solution to the equation

d) the given value is not a solution to the equation

Step-by-step explanation:

a) 2k + 6 = 34

   2k = 34 - 6

   2k = 28

   k = 14  (the question states that k = 20 but that is not true, there for k = 20 is not a solution to the equation)

b)  

     (the question states also states that y = 27, therefore the given value of y is a solution to the equation)

c) 23 = 3 + 4g

   4g = 23 - 3

   4g = 20

   g = 5  (the question states also states that g = 5, therefore the given value of g is a solution to the equation)

d)  

     (the question states that p = 24 but that is not true, therefore p = 24 is not a solution to the equation)

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
