The sum of 3 and the quotient of a number and 4 is 22. what is the number

 x = 76

Step-by-step explanation:

3 + x/4 = 22

-3           -3

x/4      = 19

time both sides by 4

x         = 76

Step-by-step explanation:

The projection of u on v is expressed as;

Given

u=1.6i+3.3j

v=-2.1i-.5j

u*v = (1.6i+3.3j )*(-2.1i-0.5j )

u*v = 1.6i(-2.1i) + 3.3j(-0.5j)

u*v = -3.36 - 1.65

u*v = -5.01

|v|² = (√(-2.1)²+(-0.5)²)²

|v|² = (-2.1)²+(-0.5)²

|v|² = 4.41+0.25

|v|² = 4.66

Substitute into the formula;
