Answer:

There are 324 boys and 32 girls in grade 8 at Euclid's middle school.

Explanation:

Let's break down the information provided to solve for the number of boys and girls in grade 8. Let's assume the number of boys in grade 8 is represented by "b" and the number of girls is represented by "g."

From the given information:

"Thirty-four more than four times the number of girls is equal to half the number of boys":

4g + 34 = (1/2)b

"There are 356 grade 8 students":

b + g = 356

Now we have a system of two equations with two variables. We can solve this system to find the values of b and g.

Using equation 2, we can rewrite it as:

b = 356 - g

Substituting this value in equation 1:

4g + 34 = (1/2)(356 - g)

Multiplying both sides by 2 to eliminate the fraction:

8g + 68 = 356 - g

Combining like terms:

9g + 68 = 356

Subtracting 68 from both sides:

9g = 288

Dividing both sides by 9:

g = 32

Now we can substitute the value of g back into equation 2 to find the value of b:

b + 32 = 356

b = 356 - 32

b = 324

Therefore, there are 324 boys and 32 girls in grade 8 at Euclid's middle school.
