Since these angles clearly form a circle and a circle is 360 degrees,
120-x+2x+16+3x-72=64+4x=360. Subtracting 64 from both sides, we get
4x=296 and by dividing both sides by 4 we get x=74

mitt are 24 peanuts. This represents 75 present of the bag peanut.how many peanut were originally in the bag.

In-s [12.5K]

Let x be the number of peanuts originally in the bag.

24/x = 75/100

24 = .75x

x = 32

There were 32 peanuts originally in the bag

PLZ ANSWER ASAP! What is the solution of the system of equations? {7/2x−1/2y=9/2 3x−y=5 Enter your answer in the boxes.

Reil [10]

$\frac{7}{2} x - \frac{1}{2} y = \frac{9}{2} same \: as \: 7x - y = 9$
7x-y=9
3x-y=5 (multiply by -1 both sides of the equation)

7x-y=9
-3x+y=-5 (now add both equations)

7x-3x-y+y=4
4x=4 (divide by 4 both sides of the equation)

x=1

y=3x-5=3×1-5=-2

y= -2

answer: x=1, y=-2
