Linda,\ aldo\ and\ tom\ sent\ a\ total\ of\ 147\ text\ messages\ during\ the\ weekend.\ Tom\ sent\ 4\ times\ as\ many\ messages\

BabaBlast [244]

Answer:

Linda Sent 32 messages, Aldo sent 23 messages and Tom sent 92 messages.

Step-by-step explanation:

Let number of messages sent by Linda=l

Let number of messages sent by Aldo=a

Let number of messages sent by Tom=t

Linda, Aldo and Tom sent a total of 147 messages

t+a+l=147.........(i)

If Tom sent 4 times as many messages as Aldo,

t=4a ......(ii)

Linda Sent 9 more messages than Aldo

l=a+9.........(iii)

We are required to find the number of messages each sent i.e. l, a and t

Substituting Equations (ii) and (iii) into (i)

t+a+l=147

4a+a+(a+9)=147

6a+9=147

6a=147-9

6a=138

a=138/6=23

From (ii). t=4a

t=4X23=92

From (iii), l=a+9=23+9=32

Therefore:

Linda Sent 32 messages, Aldo sent 23 messages and Tom sent 92 messages.

In AWXY, m_W = (10x +17), m_X = (2x – 9)", and m_Y = (3x + 7)º.<br> Find mZY

ella [17]

Answer:

$m\angle Y=40^\circ$

Step-by-step explanation:

Suppose we have a triangle WXY whose internal angles are:

$m\angle W = 10x+17$

$m\angle X=2x-9$

$m\angle Y=3x+7$

The sum of the measures of the angles must be 180°, thus:

$10x+17 + 2x-9+3x+7=180$

Simplifying:

15x + 15 = 180

Subtracting 15:

15x = 165

Dividing by 15:

x = 11

Thus, the measure of angle Y is

$m\angle Y=3x+7=3*11+7=33+7=40$

$\mathbf{m\angle Y=40^\circ}$
