Answer:
(6, 2.5 )
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k substitute the coordinate point (5, 3 ) into the equation, that is
3 = 
( multiply both sides by 5 )
15 = k
y = 
← equation of variation
Using (x, 2.5 ) with y = 2.5 , then
2.5 = ( multiply both sides by x )
2.5x = 15 ( divide both sides by 2.5 )
x = 6
Thus point is (6, 2.5 )
Answer:
In the two different ways we have solved the given equation as
Step-by-step explanation:
Given expression is
To simplify the given expression in two ways:
First way:
Given
Multiplying 3 on both sides
(adding the like terms)
Dividing by 3 on both sides
Therefore the given expression is solved that
Another way:
Given
(adding the like terms)
Therefore the given expression is solved that
In the two different ways we have solved the given equation as
Answer:
-4 - 17x
Step-by-step explanation:
Anything enclosed in parentheses must be done first if possible. (3x + 2) is inside two sets of parentheses, but nothing can be done with 3x + 2.
Multiplication must be done next. [6(3x+2)-x] becomes 18x + 12 - x, or
17x + 12.
Now we have 4 - 17x - 12 + 4. Combining like terms through addition and subtraction, we get 4 - 12 + 4 - 17x, or -4 - 17x.
Answer: 141.3cm^3
Step-by-step explanation:
Pi((3)^2)(-5)
Pi(9)(5)
Pi(45)
3.14×45
141.3
< is the correct symbol
3 x 2/4 = 1.5
1.5 is less than 3
so 1.5 < 3
