Answer:
D. 60
Step-by-step explanation:
To find an equal number of numbers the sum has to be equal to 6*x.
A*5+b*2=145
a +b =50 | * -2
5a +2b=145
-2a -2b = -100
----------------------
5a-2a = 145-100
3a= 45
a=45:3
a=15 questions are worth 5 p
b=50-15=35 questions worth 2 p
we must avoid the bracket
a,4(3-×)...........given
4×3-4×........distributive property r applied
12-4×...........simply equivalent equation
Step-by-step explanation:
that is it
500-40x ≥ 200
-40x≥ -300
x ≤ 7.5
