Answer:

100 times

Step-by-step explanation:

multiples of 3 on a number cube are 3 and 6

probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3

1/3 x 300 = 100

Write an equation for the line in slope intercept form to parallel to -x + 3y =-2 that contains the point (12,7)
kvasek [131]

The parallel lines have the same slope.

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

We have

-x+3y=-2\qquad|\text{add x to both sides}\\\\3y=x-2\qquad|\text{divide both sides by 3}\\\\y=\dfrac{1}{3}x-\dfrac{2}{3}\to m=\dfrac{1}{3}

Therefore searched line equation is:

y=\dfrac{1}{3}x+b

The line passes through point (12, 7). Put the coordinates of the point into the equation of the line:

7=\dfrac{1}{3}(12)+b\\\\7=4+b\qquad|\text{subtract 4 from both sides}\\\\3=b\to b=3

Answer: y=\dfrac{1}{3}x+3

A football stadium holds 17,700 seats. The lower level has 300 seats less than 4 times the number of seats in the upper level. T
grigory [225]

Answer:

6x + 200 = 17,000

Step-by-step explanation:

Lower level = 4x - 300

Mid level = 2x + 500

Combine the two equations to find the number of seats in the upper level

(2x + 500) × (4x - 300) = 17,000

Combine like terms

4x × 2x + 500 - 300 = 17,000

<em>6x + 200 = 17,000</em>
