4.25x + 7 = 53.75 solve this equation for x

4.25x + 7 = 53.75

Subtract 7 from both sides:

4.25x = 46.75

Divide both sides by 4.25:

X = 46.75 / 4.25

x = 11

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°

hope this

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
