Given

The attached histogram

Required

The number of times the team gain at least 6 yards

From the question, the entry that fall in the category of at least 6 yards are:

$6\ to\ 8$ , $9\ to\ 11$ and $12\ to\ 14$

Their frequencies are:

#6) BRAINLIEST + 10 + POINTS! :D

kumpel [21]

Answer:

Step-by-step explanation:

Notice that if we divide our given equation (2x - 4 = 6) by 2 from both sides, we get:

(2/2)x - (4/2) = (6/2)

x - 2 = 3

Now, notice what happens if we multiply this by -3:

-3 * (x - 2) = 3 * (-3)

-3 * x + (-3) * (-2) = -9

-3x + 6 = -9

This matches B.

Hope this helps!

Last Sunday a certain store sold copies of Newspaper A for $1 and Newspaper B for 1.25. If r percent of the stores revenue came

Oksanka [162]

Answer:

Option 400p/500-p

Step-by-step explanation:

Let the number of newspaper A sold be 'x'

and the number of newspaper A sold be 'y'

Therefore,

Total revenue = $1x + $1.25y

Total newspapers sold = x + y

Therefore,

according to the question

r = $\frac{x}{x + 1.25y}\times100$ ..........(1)

and,

p = $\frac{x}{x + y}\times100$

(x + y)p = 100x

y = $\frac{x}{p}\times100-x$

y = $\frac{x(100-p)}{p}$

substituting y in 1

r = $\frac{x}{x + 1.25(\frac{x(100-p)}{p})}\times100$

r = $\frac{100p}{p+125-1.25p}$

r = $\frac{100p}{125-0.25p}$

multiply and divide the RHS with 4

we get

r = (400p)÷(500-p)

hence,

Option 400p/500-p
