Answer:
1) d < -2
2) b < 3
Step-by-step explanation:
1) d+3< 1
subtract both sides by 3
d+3 -3 < 1-3
d<-2
2) b+6< 9
subtract both sides by 6
b+6 -6 < 9 -6
b< 3
Answer:
Step-by-step explanation:
=3+(18-6)+20÷4
=3+12+20÷4
=3+12+5
=20
use BODMAS rule (Bracket of Division, Multiplication, Addition, and Subtraction)
In multiplication, a negative times a positive has a negative answer. if both are positive or both are negative, the answer is positive.
5 * -5 = -25
-5* -5 = 25
in divisions say you have
-5/5 = -1
-5/-5= 1
5/-5= -1
in addition and subtraction, subtracting a negative means to add the two numbers. adding a negative means to subtract the second number.
5+ (-5) = 0
5- (-5) = 10
Answer:
simple
Step-by-step explanation:
-4-4=3x
-8=3x
x=8/3
x=2.678
Let the total ribbon Zoe had was x feet.
Out of x feet, she used 3/8 part of it.
Hence, 
3/8 part of the original ribbon is equal to 9 feet.
Hence, we get
=> Multiply 8 on both sides.
Divide both sides by 3
Zoe had 24 feet of ribbon in starting... Answer
