#1 (15)
50%= 1/2
1/2 of 30 is the same as 30÷2=15
#2 (20kg)
25%= 1/4
1/4 of 80 is the same as 80÷4= 20
#3 (30cm)
1/3 of 90 is the same as 90÷3=30
#4 (8m)
2/3 of 12 is the same as 12÷3= x2
12÷3= 4(2)= 8
#5 (70)
10% = 1/10
1/10 of 700 is the same as 700÷10= 70
#6 (280)
40%= 4/10
700÷10=x(4)
70(4)=280
#7 (2700 m)
9/10
3000÷10=x(9)
300(9)= 2700
Answer:
Step-by-step explanation:
+ means we are approaching from the right
- means we are approaching from the left
We are given that if x < 5, it is x² + 5x + 4
So to find we would plug in 5 into that piecewise function part:
5² + 5(5) + 4 = 54
We would be approaching y = 54 if we approach from the left.
We are given that x > 5, it is -4x + 3
So to find we would plug in 5 into that piecewise function part:
-4(5) + 3 = -17
We would approach y = -17 if we approached from the right.

Answer:
18.75pages
Step-by-step explanation:
158 = 8p + 12
158 - 12 = 8p
146 = 8p
P = 146/8
P = 18.75
