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}

what is the surface area of a rectangular prism that has a height of 5cm a width of 10cm and a depth of 4cm
Kamila [148]

2(5*10)+2(10*4)+2(5*4)=

2(50)+2(40)+2(20)=100+80+40=

220 cm^2

I found the answer by finding the areas of the 3 different sides, multiplying each area by 2 since each side has another side that is equal on a rectangular prism, then adding all of them together.
