Find the value of x in the equation 3(x + 2) = x.

1 answer:

4 0

First number = x
Consecutive number = x+1
"squares differ by 31" means to square both numbers and subtract them:
(x+1)^2 - (x)^2 = 31
x^2+2x+1 - x^2 = 31
2x+1 = 31
2x = 30
x = 15 (first number)
x+1 = 15+1 = 16 (consecutive number)

A coordinate map of the local grocery store is shown below. Ice cream is located at the point (-8,0)(−8,0)left parenthesis, minu

Alona [7]

Answer:

Step-by-step explanation:

If on the coordinate map, ice cream is located at the point (-8,0) and sprinkles are located at the point (-8,6), we can find the distance between the coordinate points using the formula;

D = √(x2-x1)²+(y2-y1)²

Given

x1 = -8, y1 = 0, x2 = -8 and y2 = 6

Substitute

D = √(x2-x1)²+(y2-y1)²

D = √(-8-(-8))²+(6-0)²

D = √0²+6²

D = √36

D = 6units

Hence the distance between the coordinate points is 6units

Answer:A. The theoretical probability for pink is 95/185 or about 51.35%

B. The theoretical probability for brown is 90/185 or about 47.82%.

C. To find the experimental probability, we will make another fraction. The number of outcomes will be the numerator and the total will be the denominator.

Pink 36/69 = 52.17%

Brown 33/69 = 47.82%
