Answer:  The correct option is (A) 80.

Step-by-step explanation:  Given that students were asked in a survey if they like peanuts, cashews, walnuts or pecans the most and the results are shown in the bar graph.

We are to find the total number of students that participated in the survey.

From the bar graph, we note that

Number of students who like Peanuts = 15,

number of students who like Cashews = 30,

number of students who like Walnuts = 10

and

number of students who like Pecans = 25.

Therefore, the total number of students that participated in the survey is

n=15+30+10+25=80.

Thus, altogether, 80 students participated in the survey.

Option (A) is CORRECT.

Can someone explain the steps for how do solve this?! I can’t get it right
Ulleksa [173]

Answer:

x = 50

m∠D = 150°

m∠F = 30°

Step-by-step explanation:

  • supplementary angles are two angles whose sum is 180°

∠D + ∠F = 180°

3x + x - 20 = 180

3x + x = 180 + 20

4x = 200

x = 200/4

x = 50

D = 3*50 = 150

∠D = 150°

F = 50 - 20 = 30

∠F = 30°

Elimination to solve the system of equation<br> x-y=5 and x+y=3
Alik [6]
X = 4 , y = -1
Explanation:
solve by elimination ie eliminate x or y from the equations by performing operations on them.
first label the equations , to follow the process.
x - y = 5 ----------------(1)
x+ y = 3 ----------------(2)
If (1) and (2) are added then y will be eliminated.
(1) + (2) gives : 2x = 8 → x = 4
now substitute this value of x into either of the 2 equations and solve for y.
let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1
check in (1) : 4-(-1) = 4+1 = 5
check in(2) : 4 - 1 = 3
