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 )

marissa [1.9K]

No, not reasonable.

98.3 divides by 52.6

Brady used compatible numbers 100 divided by 5 =20

He should've used 100 divided by 50 = 2

Car A travels 20 mph faster than Car B. In the same time that Car A travels 252 miles, Car B travels 196 miles. Find their speed

RoseWind [281]

Answer:

A = 70

B = 90

Step-by-step explanation:

We know that Car A travels 20 mph faster than Car B.

Assuming the speed of Car B to be x and the speed of Car A to be x+20, we can write:

$\frac{196}{x} =\frac{252}{x+20}$

Taking the reciprocal of both sides to make x the subject:

$196(x+20)=252x$

$196x+3920=252x$

$252x-196x=3920$

$56x=3920$

$x=70$ ---> speed of Car A

Finding the speed of Car B: $x+20 = 70+20=90$

Therefore, the speed of Car A = 70 and the speed of Car B = 90.
