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:
d) the numbers are 9 and 12
Step-by-step explanation:
set each factor equal to 108:
m-12=108
m = 120
*************
m-9=108
m=117
*************
120 and 117 are 3 units apart
****************
9 x 12 = 108
Cos-1 divided by (15/21) rounded to nearest tenth 44.4
If the equation is -2y=0, you have to add the the -2y to the other side, so it turns out to be 0=+2y.
