Answer:

x = 14

Step-by-step explanation:

let the number be x.

4 times the number = 4x
10 added to 4 times the number = 4x + 10

now,

5 times the number = 5x
4 less than 5 times the number = 5x - 4

Given that,

4x + 10 = 5x - 4

moving all x terms to the LHS and the constants to the RHS

4x - 5x = -4 - 10

-x = -14

dividing both sides by -1

x = 14

Cosθ=0.5 (to nearest degree)

mylen [45]

Step-by-step explanation:

Hey, there!!

Given,

cos theta = 0.5

To convert it into angle, you have to take cos to right side making it (cos inverse).

Therefore, theta = cos inverse (0.5)

= 60°.
