Hi:) I need help with part 9(ii) ? Thanks :)!

Goshia [24]

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2 $\left[\begin{array}{ccc}10.5\\10\\\end{array}\right]$ + 5 $\left[\begin{array}{ccc}0\\3\\\end{array}\right]$ = 7t

$\left[\begin{array}{ccc}21\\20\\\end{array}\right]$ + $\left[\begin{array}{ccc}0\\15\\\end{array}\right]$ = 7t

$\left[\begin{array}{ccc}21\\35\\\end{array}\right]$ = 7t , thus

t = $\frac{1}{7}$ $\left[\begin{array}{ccc}21\\35\\\end{array}\right]$ = $\left[\begin{array}{ccc}3\\5\\\end{array}\right]$

Hence T = (3, 5 )

let

brenda: b

will: 3b

b + 3b = 240

4b = 240

b = 60 lbs (BRENDA)

3b = will

180 = WILL
