Assuming you are supposed to solve for the variable "t",
9 - (t ÷ 6) = 5
Subtract 9 from both sides.
9 - 9 - (t ÷ 6) = 5 - 9
Simplify.
- (t ÷ 6) = -4
Distribute -1 throughout the parenthesis.
-t ÷ -6 = -4
Multiply both sides by -6.
-t ÷ -6 × -6 = -4 × -6
Simplify.
-t = 24
Divide both sides by -1.
-t ÷ -1 = 24 ÷ -1
Simplify.
t = -24
Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
Answer:
5 presents
Step-by-step explanation:
40 presents in 2 hours
20 presents in 1 hour (divide by 2)
20 presents in 60 minutes ( 1 hour is 60 minutes )
5 presents in 15 minutes ( divide by 4)
The slope is -4/5 and the Y intercept is 4.
