Answer:

5%

Step-by-step explanation:

1. We assume, that the number 48 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 48, so we can write it down as 100%=48.

4. We know, that x% equals 2.4 of the output value, so we can write it down as x%=2.4.

5. Now we have two simple equations:

1) 100%=48

2) x%=2.4

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=48/2.4

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.4 is what percent of 48

100%/x%=48/2.4

(100/x)*x=(48/2.4)*x       - we multiply both sides of the equation by x

100=20*x       - we divide both sides of the equation by (20) to get x

100/20=x

5=x

x=5

now we have:

2.4 is 5% of 48

Right answer is -14


ADDITION METHOD

The whole problem with solving a system of equations is that you cannot solve an equation that has two unknowns in it. You need an equation with only one variable so that you can isolate the variable on one side of the equation. Both methods that we will look at are techniques for eliminating one of the variables to give you an equation in just one unknown, which you can then solve by the usual methods.
The first method of solving systems of linear equations is the addition method, in which the two equations are added together to eliminate one of the variables.
Adding the equations means that we add the left sides of the two equations together, and we add the right sides together. This is legal because of the Addition Principle, which says that we can add the same amount to both sides of an equation. Since the left and right sides of any equation are equal to each other, we are indeed adding the same amount to both sides of an equation.

If a line with a slope of -2 crosses the yaxis at (0,3) what is the equation of the line
Sliva [168]

Answer:

y=-2x+3

Step-by-step explanation:

Notice that with the provided information they are given you not ust the slope of the line (-2), but also the y-intercept (the point where the line crosses the y-axis which happens when x=0).

So you can directly write the equation of the line in slope-intercept form [y=mx+b where "m" is the slope and "b" the y-value when x=0].

Such gives us:

y=-2x+3
