Lisa and conner had $360 altogether. After Connor gave Lisa 40% of his money, she had the same amount of money as he did. How mu
timama [110]

Answer:

Conner had 225 in the beginning

Step-by-step explanation:

Let lisa's money be L

and Conots money be C

C+L= 360----------------1

Connor gave Lisa 40% of his money,

L= 0.4C+L

C= 0.6C

L=0.4C+L=C

C=0.4C+L---------------2  <em>she had the same amount of money as he did</em>

C-0.4C=L  

`0.6C=L

Put L=0.6C in eqn 1

C+0.6C= 360

1.6C= 360

C= 360/1.6

C=225

C+L= 360----------------1

225+L=360

L= 360-225

L= 135

Drag the point around to graph more horizontal lines. What is the general equation of a horizontalline?
svetlana [45]

A horizontal line is one for which the value of y is the same for the entire length of the line. Therefore this type of line can be expressed as below:

y=c

Where "c" is a constant that changes the position of the line on the coordinate plane. If c is equal to 2, then we have a constant line that crosses the y-axis at the position 2 for example.

Helppp!! 21 - 3y = -18<br> 3x+ y = -5
Ugo [173]

Answer:

(-3,4)

Step-by-step explanation:

A system of equations is given to us. The given equations are ,

\implies 2x - 3y = -18

\implies 3x + y =-5

We need to plot the graph and find the solution of the given system . For that refer to attachment . The point at which both the lines of the graph will intersect each other will be the solution of the given system of equations .

From the graph we can see that it intersect at (-3,4) . Therefore the Solution is ,

\longrightarrow \underline{\underline{ Solution = (-3,4)}}

What is the solution for this equation? 3x - 1 = 5x - 11
Gennadij [26K]
3x - 1 = 5x - 11
Add 1 to both sides.
3x = 5x - 10
Subtract 5x from both sides.
-2x = -10
Divide by -2.

x = 5

If m∠ADB=(6x−4)° and m∠BDC=(4x+24)°, find the value of x such that ∠ADC is a right angle.
spayn [35]

To make ∠ADC is a right angle, value of x will be 7.

From given figure, it is observed that Angle ADC is combination of two angles ADB and BDC.

                ∠ADC=∠ADB+∠BDC

Since, ∠ADC is right angle.

 So,  ∠ADC=90 degree

       90=∠ADB+∠BDC

     6x-4+4x+24=90\\     10x+20=90\\      10x=70\\       x=7
