Answer: 5x - 7 = 9

Explanation:

Let's think the unknown number as, "x"

Product means multiplication so 5 multiply the unknown number which is 5x. Seven less mean's to subtract so 5x - 7. And then the result is 9. So 5x - 7 is 9 or 5x - 7 = 9.

Sorry for not providing enough explanation last time. But I hope this is enough-

12. Use a trigonometric ratio to find the measure of O in the triangle below. Give your answer to the nearest degree.

Given :-

A right angled triangle with two sides 10cm and 9cm .

To Find :-

The value of theta .

Solution :-

At angle theta , 9cm side will be considered as the perpendicular and 10cm side will be hypotenuse . So , as we know that ;

$\longrightarrow sin\theta =\dfrac{perpendicular}{hypotenuse}$

Substituting the respective values,

$\longrightarrow sin\theta =\dfrac{9cm}{10cm}$

Simplify,

$\longrightarrow sin\theta= 0.9$

Take arcsin both sides ,

$\longrightarrow \theta =sin^{-1}(0.9)$

$\\\longrightarrow\underline{\underline{\theta = 64.15^o }}$

Hence the required answer is 64.15° .

Two times a number, plus five, equals the number, minus five.

kirza4 [7]

Answer:

x= -5

Step-by-step explanation:

let the number be x.

2x+5= -5 ====> equation

2x= -5-5. (shifted the +5 to the other side)

2x= -10

x= -10/2 ( shifted 2 on the other side as it was multiplying with x)

x= -5
