Answer:
51+x-5+y-6=180
x+y=180-51+5+6
X+y=140
Answer x=77 y=63
(those 2 lines with the arrows are perpendicular so their angles are the same 72° and (x-5)=77-5= 72°)
probability : 1/3
Explanation:
- weightlifting benches : 4
probability = selected/total
Here,
- probability = 4/12 = 1/3 = 0.33
Answer:
-( 2x^2+6-4/x)
that what i got when you divide
Answer:
80 just did it in a lesson
Step-by-step explanation:
There are a total of 30 students in the class. The equation used to solve the question is,
× x = 24.
Step-by-step explanation:
Step 1; It is given that 24 students make up eight-tenths of the entire class. Assume the total number of students in class is x. So we have 24 will equal eight-tenths of x, as x is the total number of students.
The equation is
× x = 24. Multiply both sides by 
× x ×
= 24 ×
, The
and
cancel out each other on the LHS.
x =
= 30.
So there are 30 students in the class in total i.e. x = 30.
Step 2; To draw the bar chart, measure the entire length of the bar and divide it by 10. Shade eight-tenths of the bar and name it students that are going to the trip = 24, the remaining two-tenths is named students not going = 6.
