8x + 5y = 27.15
what is x and y?

Step-by-step explanation:

Simplifying

8x + 5y = 27.15

Solving

8x + 5y = 27.15

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5y' to each side of the equation.

8x + 5y + -5y = 27.15 + -5y

Combine like terms: 5y + -5y = 0

8x + 0 = 27.15 + -5y

8x = 27.15 + -5y

Divide each side by '8'.

x = 3.39375 + -0.625y

Simplifying

x = 3.39375 + -0.625y

Infinite solutions

Step-by-step explanation:

There is no one right answer, plug in numbers for x and you will see

y = -8/5(x) + 27.15/5

answer: ur mum is gay

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
