NEED HELP ASAP

Answer:

x=55

Step-by-step explanation:

The angles are corresponding angles and corresponding angles are equal

3x-60 = x+50

Subtract x from each side

3x-60-x = x+50-x

2x-60 =50

Add 60 to each side

2x-60+60=50+60

2x=110

Divide by 2

2x/2 =100/2

x =55

Paha777 [63]

Answer:

$y\le\dfrac{1}{2}x+2$

Step-by-step explanation:

On a coordinate plane, a solid straight line has a positive slope and goes through (negative 4, 0) and (0, 2). This line has the equation

$y-0=\dfrac{2-0}{0-(-4)}(x-(-4))\\ \\y=\dfrac{1}{2}(x+4)\\ \\y=\dfrac{1}{2}x+2$

The origin belongs to the shaded region, so its coordinates must satisfy the inequality. Since

$\dfrac{1}{2}\cdot 0+2=2\ge 0,$

then the correct inequality is

$y\le\dfrac{1}{2}x+2$

Nataly [62]

Answer:

let the no be x ..then,

10% of x =80,000

10x=80,000*100

x=80,00,000/10

x=8,00,000

hence 10%of 8,00,000 is 80,000
