Answer:
n = -0.7
Step-by-step explanation:
-2n+1.8=3.2
subtract 1.8 from both sides of the equation:
-2n = 1.4
divide both sides by -2:
n = -0.7
Answer: (6,12)
Step-by-step explanation:
3+3=6
4+9=12
Answer:
p = 121
Step-by-step explanation:
inveresly proportional
pq² = k
find k the constant of proportionality
p is 16 when q is 11,
16 * 11² = k
k = 1,936
----------------------------
pq² = 1,936
determine p when q is equal to 4.
p * 4² = 1,936
16p = 1,936
p = 1,936/16
p = 121
