Solve the following simultaneous equation using either the substitution method or the elimination method, showing all the necess

slavikrds [6]

Answer:

$x=1\frac{83}{91}\\y=-2\frac{73}{91}$

Step-by-step explanation:

#Using the method of substitution and replacement of unknown values.

Given that

$\frac{3}{2}x+\frac{2}{3}y=1...(i)\\and\\\frac{1}{6}x-\frac{3}{5}y=2...(ii)\\$

Express eqtn (ii) in terms of x

$\frac{1}{6}x=2+\frac{3}{5}y\\x=12+\frac{18}{5}y$

Replacing for x in eqtn (i)

$\frac{3}{2}(12+\frac{18}{5}y)+\frac{2}{3}y=1\\18+\frac{27}{5}y+\frac{2}{3}y=1\\18-1=-\frac{91}{15}y\\y=-2\frac{73}{91}$

Substitute y value in eqtn(ii) to obtain x

$Y=-2\frac{73}{91}\\\frac{1}{6}x-\frac{3}{5}y=2\\x=2+\frac{3}{5}(-2\frac{73}{91})\\x=1\frac{83}{91}$

The scale of map is 14 cm long. Calculate the actual length of the river in kilometres

Helen [10]

Answer:

Step-by-step explanation:

Given:

1cm = 85 km (on the map)

so map is

14 x 14 long or 85 x 85

Part A:

since the map is 14cm long, and the river is also 14 cm long, and each centimeter is equal to 85km, that means, =

14 x 85 = 1190km

so the river is 1190km long

Part B:

we can use just convert 765 into map cm to get answer,

sooo

765/85 = 9cm

SO THERE YOU HAVE IT:D
