The rotio of blue marbles to red marbles in a bag is 11: 9.if there are 99 blue marbles in the bag how many red marbles are there

81

Step-by-step explanation:

let the number of blue and red marbles be 11x and 9x res

pectively

then,

11x=99

x=99/11

x=9

so

no. of red marbles= 9x=9×9=81

the answer is two. hope this !

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
