1.94x - 10/8x + 4.32 = [2(1.15x+8.5)]

kipiarov [429]

$1,94x-\frac{10}{8}x+4,32=[2(1,15x+8,5)]\\\\
1,94x-1,25x+4,32=2,3x+17\\\\
0,69x+4,32=2,3x+17\ \ \ |Subtract\ 2,3x\\\\
-1,61x+4,32=17\ \ \ |Subtract\ 4,32\\\\
-1,61x=12,68\ \ \ |Divide\ by\ -1,61\\\\\boxed{x\approx7,9}

You are building a house and are making a drawing of the kitchen. the sink is 3 feet away from the dishwasher, and the sink is 8

Natasha_Volkova [10]

Consider the triangle with vertices S (sink), D (dishwasher) and F (fridge). From the conditions data SD=3, SF=8 and ∠S=48°.

Use the cosine theorem to find unknown distance:

$FD^2=SD^2+SF^2-2SD\cdot SF\cdot \cos S$ ,

$FD^2=3^2+8^2-2\cdot 3\cdot 8\cdot \cos 48^{\circ},\\ FD^2=9+64-48\cdot 0.67,\\ FD^2=40.84, \\ FD=\sqrt{40.84}, \\ FD=6.39$ feet.

Then the distance between dishwasher and fridge is 6.39 feet.

Are these dimensions reasonable is up to kitchen owner))
