Answer:

B. 33

Step-by-step explanation:

Let the number of Fuji trees be F, the number of gala be G and the total number of trees be x.

10% cross pollinated, this means 1/10 cross pollinated or 0.1x

Number of Fuji plus cross pollinated is 187.

And cross pollinated is 3/4 of total or let’s say 0.75 of total which is 0.75x

Now, adding 0.1x + 0.75x would equal 187

0.85x = 187

x = 187/0.85 = 220 trees

The total number of trees is 220.

The number of gala trees is thus 220 - 187 = 33 trees

PLEASEEEEEEE HELPPPPP
coldgirl [10]

If their perimeters are equal, we can add up all the side lengths of each triangle, and set the perimeters equal to each other to find the value of x that satisfies the equation:

x - 2 + x + 3x + 1 = 2x - 5 + x + 4 + 6x - 7

Combine like terms:

5x - 1 = 9x - 8

And finally, solve for x:

7 = 4x

x = \frac{7}{4}

Therefore, x is equal to \frac{7}{4}.

<em>Hope this helps! :)</em>
