Jessica, Miguel, and Dan sent a total of 75 text messages over their cell phones during the weekend. Dan sent 3 times as many me

SCORPION-xisa [38]

Answer:

number of messages sent by Jessica = 17

Number of messages sent by Miguel = 7

Number of messages sent by Dan = 51

Step-by-step explanation:

Let number of messages sent by Jessica = $x$

As per given statement,

Number of messages sent by Dan = $3 \imes x$ and

Number of messages sent by Jessica are 10 more than that of Miguel.

So, Number of messages sent by Miguel are 10 lesser than that of Jessica.

Number of messages sent by Miguel = $x-10$

It is also given that,

Total number of messages sent = 75

Adding the number of messages sent by each one of them and putting them equal to 75:

$x+3x+x-10=75\\\Rightarrow 5x-10=75\\\Rightarrow 5x=85\\\Rightarrow x=17$

So, number of messages sent by Jessica, $x$ = 17

Number of messages sent by Miguel, $x-10$ = 7

Number of messages sent by Dan, $3x$ = 3 $\times$ 17 = 51

The diagram shows a rectangle ABCD. The point A is (2, 14), B is (−2, 8) and C lies on the x-axis. Find

Eva8 [605]

Answer:

Step-by-step explanation:

since AB and BC are perpendicular so AB.BC=0, (scalar product)

AB=(-4, -6), and BC=(xc+2, yc-8)

AB.BC= -4x-8-6y+48 =0

so the equation of BC is 2x+3y-20=0

C is on the line BC, so 2xc+3yc-20=0, but yc=0, so xc=20/2=10

AB and CD are parallel, so det(AB, CD)=0

AB and AD are perpendicular so AB.AD=0

AB=(-4, -6) and CD =(x-10, y), AD= (x-2, y-14)

det(AB, CD)=0

x-10-y = 0 equivalent to x-y = -10

AB.AD=0

-4x+8-6y+84=0 equivalent to 2x+3y=44

let's solve

x-y = -10

2x+3y=44

-5y = -64, y = 64/5, x= -10+64/5=14/5

finally D(14/5, 64/5)
