11 more than five if a certain number is twenty more than 2 times of that number. what is the number?
Thepotemich [5.8K]
11 more than five of a certain number would be written as 5x+11 and it is (means equal to) twenty more than two times that number, which would be 2x+20. So the equation would be
5x+11=2x+20
-2x -2x (get the x's on one side)
3x+11=20
-11 -11 (get the numbers on one side)
3x=9
/3 /3 (divide by 3, so you can get the x by itself)
X=3 (the number is 3)

70 is what percent of 56
Cloud [144]
Percent means parts out of 100
so x%=x/100

'of' means mutiply

70 is what percent of 56
70=x/100 times 56
solve for x

70=x/100 times 56
mutliply both sides by 100
7000=x times 56
divide both sides by 56
125=x

answer is 125%

2. Translate the following equation into a verbal sentence. x + 5 = 2(7 + x)
Stells [14]

Answer:

G

Step-by-step explanation:

Some points to note

  • "is" means equal
  • "times" means multiplication
  • "quotient" means division
  • "sum" is addition

Now, let's look at the left side of the equation.

It is "x + 5"

This means the sum of the number x and 5, or the number x plus 5

It eliminates F and J

Now, let's look at right side of equation.

It is "2(7+x)"

"7+x" is in brackets, so this is the sum of 7 and x. Then it is multiplied by 2. Thus, we can say:

"2 times the sum of 7 and x"

From the choices G and H left, we select G to be correct.

Suppose Cotangent (theta) = StartFraction 5 Over 12 EndFraction, where Pi less-than theta less-than StartFraction 3 pi Over 2 En
Agata [3.3K]

Answer:

Sin theta = 12/13

Step-by-step explanation:

From the question;

Cot theta = 5/12

Kindly recall;

Cot theta = 1/ tan theta

Hence, tan theta = 12/5

Mathematically

tan theta= opposite/adjacent

to get hypotenuse, we will use Pythagoras’ theorem which states that the square of the hypotenuse equals sum of the squares of the two other sides

let hypotenuse be h

h^2 = 12^2 + 5^2

h^2 = 144 + 25

h^2 = 169

h = √169

h = 13

But sine theta = opposite/ hypotenuse = 12/13
