7 x 3 = 21 so it is 21 ft cm your welcome
19,008 I just used a calculator
For m it’s 1,1/3and -5/3 you will get different values when plug the different values of n
Answer:
y = 42
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use an ordered pair from the table.
Using x = 2 when y = 12, then
12 = 2k ( divide both sides by 2 )
6 = k
y = 6x ← equation of variation
When x = 7, then
y = 6 × 7 = 42
Answer:
x=3
Step-by-step explanation:
15-7x=5x-21
12x=36
x=3
