Answer:
∠ HCF = 108°
Step-by-step explanation:
∠ ABG and ∠ HCF are alternate exterior angles and are congruent, thus
12x = 11x + 9 ( subtract 11x from both sides )
x = 9
Thus
∠ HCF = 11x + 9 = 11(9) + 9 = 99 + 9 = 108°
Answer:
Plug in a 3 every time you see an "x" and the left side should equal the right side
Step-by-step explanation:
none are correct. the right answer is 4y=16x-8 is equivalent to y=4x-2
Answer:
375 girls
Step-by-step explanation:
Let the number of girls in the school be y.
Then, we can write the equation:

We can now solve for y by multiplying both sides by




Therefore there are 375 girls in the school.
