Answer:
4
Step-by-step explanation:
Given data
Number of student= 3
Total amount= 12000
Ratio= 6:5:x
Combined ratio= 6+5+x= 11+x
Applying the part to all method
if student number 2 got sh 4000
then
5/11+x= 4000/12000
5/11+x= 1/3
cross multiply
11+x= 15
x= 15-11
x= 4
Hence the value of x is 4
Answer:
-7y^2-x+11y
Step-by-step explanation:
Answer:
m < C = 60
...........
Step-by-step explanation:
m < B = m < E = 70
m < C= 180 - ( 70+50 ) = 60
Answer:
x ≥ -2 AND y < 2x
Step-by-step explanation:
the equation for the vertical line is x = -2
the inequality crosses the y-axis at 0 and it's slope is 2 because if you are at the point (-2,-4) you must go up by 4 and then to the right by 2 which reduces to 2
we can write the equation now as:
y = 2x
the shaded portion indicates the solutions to both of these equations so we can say that:
all values that are greater than or equal to -2 AND values less than y=2x
