Answer:
see explanation
Step-by-step explanation:
(1)
Given
= - 0.3
Since n is divided by 5 then use the inverse operation, multiplication.
Multiply both sides by 5 to clear the fraction
n = 5 × - 0.3 = - 1.5
(2)
Given
- 2n = 4
← change to an improper fraction
- 2n = 
Since n is multiplied by - 2 then use the inverse operation, division.
Divide both sides by - 2
n =
= - 
Answer:
x = 21
Step-by-step explanation:
Multiply both sides by 16
3/4 x 16 = x - 9
2 Simplify 3/4 x 16 to 48/4
48/4 = x - 9
3 Simplify 48/4 to 12
12 = x - 9
4 Add 9 to both sides.
12 = x - 9
5 Simplify 12+9 to 21
21=x
6 Switch sides.
Answer: x=21
Answer: 5/6
Step-by-step explanation:
(2/3×2/2)+(1/6×1/1)=?
4/6+1/6=5/5
It is 18 because it is a square so all the sides have to be the same so that would make it 18
