1819 T1W09 Math GRO6 Assessment Task 01 v01
Use the following information to answer questions 4 and 5
Wells College in Aurora, New York was previously an all-girls college. In 2005, the college began to allow boys
to enroll. By 2012, the ratio of boys to girls was 3 to 7.
4. Write an equivalent ratio to 3 boys for every 7 girls. Prove that the ratios are equivalent and include
appropriate labels. (2 points)

i believe that is true.

step-by-step explanation:

hope my answer has you if not i'm sorry.

its 4 because 2 times 2 is 4, if you double the number two you get four

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
