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)
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%
Answer:
n < 3
Step-by-step explanation:
6n + 9n < 50
15n < 50
n < 50/15
n < 3.33
Approximately
n < 3

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.
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
