Answer:
q = r
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given 2q – r = 4p ...(i)
2r = q...(ii)
r = 2p ...(iii)
Substitute 2r = q in equation (i)
<em> 2(2r) – r = 4p </em>
3 r = 4 p
<em> 2 r + r = 4 p</em>
2 r + 2 p = 4 p
2 r = 2 p
<em> q = r</em>
Y = 4
3x + 4x = 43
3(9) + 4x = 43
27 + 4x = 43
4x = 43-27
4x = 16
16/4 = x
4=x
x=4
Answer:
39 students
Step-by-step explanation:
let x represent the number of students taking both current event and foreign language
there are : 70 eight grader taking current event and 54 taking foreign
70+54-x=93
-x=93-124
x= 31 students taking both
number of eighth graders take only a current events class and not a foreign language class: 70-31=39 students
Answer:
8x + 9
Step-by-step explanation:
The total number of people splitting the cost equally = Rocco and five friends = 6 people
The total cost to play paintball can be represented by the expression (48x+54)
The cost for each person is calculated as: The total cost to play paintball/ Total number of people
= (48x+54)/6
= 48x/6 + 54/6
= 8x + 9
Therefore, the cost for each person is
8x + 9
The correct answer is D.12
