Answer:
6
Step-by-step explanation:
Given I varies inversely with R then the equation relating them is
I = 
← k is the constant of variation
To find k use the condition R = 12 when I = 3
k = IR = 3 × 12 = 36
I = 
← equation of variation
When I = 6, then
6 = , hence
R = 
= 6
Answer:x=2, y=3
Step-by-step explanation:
solving this equation simultaneously
-9x - 2y=-12.............(1)
2x + 5y=-11.. ...........(2)
Using elimination method
Multiply equation 2 by 2 and equation 1 by 5
-45x -10y= -60...........(3)
4x + 10y=-22...............(4)
Subtracting equation 2 from 1
-41x + 0=-82
41x=82
x=82/41
X=2
To find y put x in equation 1
-9x - 2y= -12
-9(2)-2y=-12
-18-2y=-12
-2y=-12+18
-2y=6
Y= 6/2
Y=3
X=2, Y=3
Answers: 10 Spelling and 16 Vocabulary
Step-by-step explanation: This is the correct answer because
16 x 5 = 80
10 x 2 = 20
80 + 20 = 100
