Using scalar multiplication, it is found that 5u = <10,20>.

<h3>What is scalar multiplication?</h3>
  • It is when a vector is multiplied by a constant, and it means that each term of the vector is multiplied by the constant.

In this problem, the vector is:

u = <2,4>

Since each term is multiplied by 5:

5u = <5 x 2, 5 x 4> = <10,20>.

Five times a number plus 5 has the same value as twice the number plus 10
NemiM [27]

Answer: x=5/3

Step-by-step explanation:

For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.

5x+5=2x+10

The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".

5x+5=2x+10                     [subtract both sides by 2x]

3x+5=10                           [subtract both sides by 5]

3x=5                                [divide both sides by 3]

x=5/3

Now, we have found the unknown number, x=5/3.

Find the missing side lengths​
Vera_Pavlovna [14]

Cos( 30 ) = 19√3 / x

√3 / 2 = 19√3 / x

Simplify √3 from both sides

1 / 2 = 19 / x

Multiply both sides by x

1 /2 × x = 19 / x × x

x / 2 = 19

Multiply both sides by 2

x / 2 × 2 = 19 × 2

x = 38

_____________________________

Sin( 30 ) = y / x

1 / 2 = y / 38

Multiply both sides by 38

38 × 1 / 2 = 38 × y / 38

38 / 2 = y

19 = y

y = 19
