x = \frac{13}{14}

Step-by-step explanation:

8x+4y=16

7y=15

the easiest unknown to find first is y because we have the second equation contains only y :

7y=15   we divide both sides by 7 we get : y=\frac{15}{7}

then we can substitute this value in the first equation to find x :

8x+4 \frac{15}{7} = 16

means : 8x+\frac{60}{7} = 16

8x=16-\frac{60}{7}

8x = \frac{52}{7}

divide both sides by 8 :

x = \frac{13}{14}

so the solution is (\frac{13}{14},\frac{15}{7})

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
