5 0

Answer:

x=3

Step-by-step explanation:

5(2x+1)=35

Step 1: Simplify both sides of the equation.

5(2x+1)=35

(5)(2x)+(5)(1)=35(Distribute)

10x+5=35

Step 2: Subtract 5 from both sides.

10x+5−5=35−5

10x=30

Step 3: Divide both sides by 10.

x=3

SashulF [63]

The scale of the drawing by using proportion is 3 : 5.

According to the given question.

Melissa drew a scale drawing of a city.

The width of the park in the drawing is 36 inches.

And the actual width of the park is 60 yards.

As we know that, a proportion is a fraction of a total amount, and the measures are related using a rule of three.

Therefore, the scale of the drawing by using proportion

= 36iches/ 60 yards

= 3/5

= 3 : 5

Hence, the scale of the drawing by using proportion is 3 : 5.

If cot 0= 4/3, find csc 0
miskamm [114]

Answer:

5/3

Step-by-step explanation:

Trigonometric ratio

Cot θ = Adjacent side/Opposite side

It is given that,

Cot θ  = 4/3

Adjacent side = 4

Opposite side = 3

Csc θ = Hypotenuse/Opposite side

To find the Hypotenuse

Hypotenuse² = Opposite side² + Adjacent side ² = 3²+ 4²

Hypotenuse = √(3²+ 4²) = 5

To find Csc θ

Csc θ = Hypotenuse/Opposite side = 5/3
