Answer:
x=1
Step-by-step explanation:
-2x + 4 = 5 - 3x
Add 3x to each side
-2x+3x + 4 = 5 - 3x+3x
x +4 =5
Subtract 4 from each side
x+4-4 =5-4
x =1
Answer:true
Step-by-step explanation:
The top line segment (12) is twice as long as the original, smaller (6), segment
Circumference = 2πr
3π=2πr
r=3π÷2π
r=3/2
area of a circle= πr²
=π×(3/2)²
=2.25π
Answer: yes
Step-by-step explanation:
Answer:
Tags not given out=(k/5)-40
Step-by-step explanation:
k is tag
Tags k given to student are half = k/2
Tags given to parents are= 100
Total tags given to students and parents are=(k/2)+100
So remaining tags are=k-(k/2+100)
=(k-200)/2
tags given to judges and teacher are 3/5 of remaining tags =(3/5)*((k-200)/2)
So tags not given out are =(2/5)*((k-200)/2)
=(k/5)-40 Answer
