$\bf \cfrac{4}{2(x-3)}=\cfrac{5}{3(14-x)}\implies \stackrel{\textit{distributing in the denominators}}{\cfrac{4}{2x-6}=\cfrac{5}{42-3x}} \\\\\\ 4(42-3x)=5(2x-6)\implies \stackrel{\textit{distributing again}}{168-12x=10x-30}\implies 198=22x \\\\\\ \cfrac{198}{22}=x\implies \boxed{9=x}$

Answer:

x = 9

Step-by-step explanation:

Since the angle is bisected by rhe segment then the ratio of the sides to the corresponding parts of the base are equal, that is

$\frac{15}{x}$ = $\frac{20}{12}$ ( cross- multiply )

20x = 180 ( divide both sides by 20 )

x = 9

Mason and Nora decided to swim across the river. Mason began swimming 1 minute earlier than Nora.

Mademuasel [1]

Mason:

time = t
V = 6 ft/s
Distance = v * t = 6t

Nora:

time = t - 60 [ I passed 1 minute to seconds]
V = 8 ft/s
Dsitance = v*t = 8 (t - 60)

Both distance are equal

6t = 8(t-60)
6t = 8t - 480
8t -6t = 480
2t = 480
t = 480/2
t = 240 s

Mason had been swimming for 240 seconds when both had swan the same distance.

1. solve the following simultaneous equations graphically. y = 8-x y=x-2

egoroff_w [7]

Answer:

(5,3)

Step-by-step explanation:

Well to solve the following,

y = 8 - x

y = x - 2

Graphically.

We need to graph both equations,

Look at the image below ↓

By looking at the graph we can tell the intercept point is at (5,3).

Thus,

the solution is (5,3).

Hope this helps :)
