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
F = .7p
add the original discount of 50% to the additional of 20%. the total discount is 70%. multiply the 70% (.7 as a decimal) by the original price (p) to find the final price (f).
Answer:
9 and 7
Step-by-step explanation:
multiply 7 and 1 after that it will 7 and again adding 7 + 2 so it will be 9 so the answer will be 9 and 7
Answer:
y=10
Step-by-step explanation:
4(-3)+2y=8
-12+2y=8
move the -12 0ver to the 8 by adding
2y=20
divide by 2
y=10
