A group of 266 persons consist of men, women, and children. There are four times as many men as children. And twice as many wome

lara [203]

There are 152 men, 76 women and 38 children.

Step-by-step explanation:

Total persons = 266

Let,

men = m

women = w

children = c

According to given statement;

m+w+c=266 Eqn 1

m = 4c Eqn 2

w = 2c Eqn 3

Putting value of m and w from Eqn 2 and 3 in Eqn 1

$4c+2c+c=266\\7c=266\\$

Dividing both sides by 7

$\frac{7c}{7}=\frac{266}{7}\\c=38$

Putting c=38 in Eqn 2;

$m=4(38)\\m=152$

Putting c=38 in Eqn 1;

$w=2(38)\\w=76$

There are 152 men, 76 women and 38 children.

Suppose point D is in the interior of ∠ABC

pashok25 [27]

Answer:

$ABC = 130$

Step-by-step explanation:

Given

$ABC=12x - 110$

$ABD=3x+40$

$DBC=2x - 10$

Required

Determine the measure of ABC --- <em>Missing part of the question</em>

First, we need to determine the value of x

Since, D is an interior of ABC, then

$ABC = ABD + DBC$

$12x - 110 = 3x + 40 + 2x - 10$

Collect Like Terms

$12x - 3x - 2x = 110 + 40 - 10$

$7x = 140$

Solve for x

$x = 140/7$

$x = 20$

Substitute 20 for x in $ABC=12x - 110$

$ABC = 12 * 20 - 110$

$ABC = 240 - 110$

$ABC = 130$
