AC = AB + BC
= x + 2 + 7x - 3
= 8x - 1


QR = PR - PQ
= 13y + 25 - (8y + 5)
= 13y + 25 - 8y - 5
= 5y + 20

Answer:

PR = 13y +25

QR = 5y+20

Step-by-step explanation:

<u>For figure a.</u>

AB = x+2

BC = 7x-3

AC and AB + BC coincides with each other, so they should be equal

i.e AC = AB + BC

{ We know that things which coincide with each other are equal }

Therefore,

AC = AB + BC = ( x+2 ) + ( 7x-3 ) = x+2+7x-3 = 8x-1

<u>For figure b.</u>

PQ = 8y + 5

PR = 13y +25

PR and PQ + QR coincides with each other , so they should be equal

i.e PR = PQ + QR

{ We know that things which coincide with each other are equal }

Therefore,

PR = PQ + QR

QR = PR - PQ

QR = ( 13y +25 ) - ( 8y + 5 )

QR = 13y+25-8y-5

QR = 5y+20

timama [110]

Answer:

5X + 8Y >= 300;    intersection at  (-20, 50)

Step-by-step explanation:

let t = work hours

0 < t < 30

X = time lawn mowing

Y = time babysitting.

X + Y < 30

5X + 8Y >= 300

We could solve...

X < 30 - Y

5(30 - Y) + 8Y  >=300

150 - 5Y + 8Y >= 300

3Y >=150

Y >=50

then  X < -20  

intersection at  (-20, 50)
