Answer:
x=9
y=3
Step-by-step explanation:
since all three sides of an equlateral triangle are equal:
3x+y=30 then y=30-3x
4x-2y=30
4x-2(30-3x)=30
4x-60+6x=30
10x=90
x=9
3x+y=4x-2y
x=3y
y=3
Answer:
x< -9
Step-by-step explanation:
9x-8x<-2-7
x< -9
Answer:
3.33%
Step-by-step explanation:
Factory measure=330 ml
Actual measure=341 ml
Difference between actual measure and factory measure is error
Difference=341 ml-330 ml=11 ml
Error (in ml)=11 ml
Percentage error=100* Error/Factory measure
Percentage error= 100*
Percentage error=3.33%
Therefore, the percentage error in the content is 3.33%
