In the given figure, Angle 23x and Angle 24x - 5 are equal because they form pair of Alternate Interior Angles.

So,

  • 24x - 5 = 23  x

  • 24x - 23x = 5

  • x = 5

value of x = 5,

now, measure of each angle = 23x = 23 × 5 = 115°

If a phone charges 3% every five minutes then how long will it take for the phone to charge 100%
postnew [5]

To find out how long it will take a phone to charge 100% if it charges 3% every 5 minutes, you have to put it in a fraction.

3/5

3 is the percent charged and 5 is the time.

You have to find out what 100 divided by 3 is. The answer is 33.3.

So,

3/5 times 33.3 is equal to 99.9/166.5.

It will take 166.5 minutes for the phone to charge to about 100%.

hope it helps.

can you choose mine as the brainliest answer

Which expression could be substituted for y in the second equation to find the value of x?
EastWind [94]

value of x is x=-\frac{29}{4} and value of y is y=-\frac{9}{2}

Step-by-step explanation:

We need to find Which expression could be substituted for y in the second equation to find the value of x

The given equations are:

2x-y=-10\,\,\,(1)2x - 3y= -1\,\,\,\,(2)

For putting value of y in second equation, we will find from equation 1

From equation 1:

2x-y=-10\\-y=-10-2x\\y=10+2x

Putting value of y i.e y=10+2x in equation (2) to find value of x

2x-3y=-1\\2x-3(10+2x)=-1\\2x-30-6x=-1\\-4x=-1+30\\-4x=29\\x=\frac{29}{-4}\\x=-\frac{29}{4}

So, now finding value of y by putting value of x= -29/4 in eq(1)

2x-y=-10\\2(-\frac{29}{4})-y=-10\\-\frac{29}{2}-y=-10\\-y=-10+\frac{29}{2}\\ -y=\frac{-20+29}{2}\\ -y=\frac{9}{2}\\ y=-\frac{9}{2}

So, value of x is x=-\frac{29}{4} and value of y is y=-\frac{9}{2}

6/7x - 2/5y + 5/7(y+x)
makvit [3.9K]

Answer:

\frac{6}{7} x -  \frac{2}{5} y +  \frac{5}{7} (y + x) \\  = ( \frac{6}{7}  +  \frac{5}{7} )x + ( \frac{5}{7}  -  \frac{2}{5} )y \\  =  \frac{11}{7} x +  \frac{15}{35} y \\  =  \frac{11}{7} x +  \frac{3}{7} y \\  =  \frac{1}{7} (11x + 3y)

Help<br> Solve for x in the diagram below.
Harman [31]

Answer:

X=10

Step-by-step explanation:

You can subtract 180 by 110 to get 70. Then you can do 8x+30+70=180
Add 30+70 to get 100
Subtract 100 to 180 to get 80.
8x=80
You divide 8 from both sides which leaves you with x=10.
