Answer: x = -1
Step-by-step explanation:
The problem is asking you the sum (+) of 3 times of a unknown number (let the unknown number be x) and 7, as in 3x + 7
According to the problem this expression is equal to 4,
3x + 7 = 4
1. Subtract 7 from both sides
3x = -3
2. Divide 3 on both sides
x = -1
Your final answer would be negative 1
120
times 12 - 360
it should give you the right answer if you solve the problem like that
Answer:
Step-by-step explanation:
Given radius of cylinder=5cm
Volume of cylinder=471cubic cm
Volume of cylinder=πr^2h
So πr^2h=471
3.14×5×5×h=471
78.5h=471
h=471/78.5
h=6cm
