Answer:
- 7
Step-by-step explanation:
Solve for x
3x + 3 = - 9 ( subtract 3 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
Hence
3x + 5 = (3 × - 4) + 5 = - 12 + 5 = - 7
I don’t know if you can solve it since it is an expression?
Answer:
45×7
Step-by-step explanation:
Answer:
y = 
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 the condition y = 7 when x = 3
k =
=
, thus
y =
x ← equation of variation
When x = 7, then
y =
× 7 = 
61/100, because if it is 0.(value) than it is value / 100 assuming value is 2 digits long. We cannot simplify it further because 61 is prime number.
