The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?

xeze [42]

Answer:

$222$ boys

Step-by-step explanation:

Let $x$ = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

$\frac{5}{6+5}x = 185$ (number of girls in ninth grade)

$\frac{5}{11}x = 185$

$x=407$

To find for the number of boys, we can use substitution:

$\frac{6}{6+5}x = \frac{6}{11}(407)$

$=222$

∴ There are $222$ boys in the class.

Hope this helps :)

Someone please help me before I frl cry

Anna71 [15]

Answer:

Equation: 4x = 128

$m\angle 1 = 84\degree$

$m\angle 2 = 96\degree$

Step-by-step explanation:

$m\angle 1+ m\angle 2 =180\degree$ (Linear pair angles)

-> (x + 52)° + (3x)° = 180°

-> (4x + 52)° = 180°

-> 4x + 52 = 180

-> 4x = 180 - 52

-> 4x = 128 ( This is the required equation)

-> x = 128/4

-> x = 32

$m\angle 1 = (32+52)\degree = 84\degree$

$m\angle 2 = (3*32)\degree = 96\degree$
