Answer:
(-2.5, ∞)
Step-by-step explanation:
You can add the opposite of the right side.
5.1(3 +2.2x) +14.25 +6(1.7x +4) > 0
15.3 +11.22x +14.25 + 10.2x +24 > 0 . . . eliminate parentheses
21.42x +53.55 > 0 . . . . . . . . . . . . . . . . . . collect terms
x + 2.5 > 0 . . . . . . . . . . . . . . . . . . . . . . . . .divide by the coefficient of x
x > -2.5 . . . . . . add the opposite of the constant
C
The equation is:
y+3/x-2=-3-(-3)/2-(-4)
Remark
There are many ways you can set up the problem. The conventional way is to set up a % equation
Givens
Let x = the number in the entire class.
Let 80% of the class = 24
Argument
80% of x = 24 Change 80% to a fraction.
80/100 * x = 24 Divide by 100
0.8 x = 24 Divide by 0.8
x = 24 / 0.8
x = 30
There were 30 people in the class.
How fast the distance between them decrease is 16mph
<h3>How to calculate the speed of an object?</h3>
Given the following parameters
Speed of the hiker = 6mph
If is it 3/11 the rate of a cyclist, then the rate of the cyclist will be:
6 = 3x/11
3x = 66
x = 22mph
Distance between them = 22 - 6
Distance between them = 16mph
Hence how fast the distance between them decreases is 16mph
