Which of the follwing is true 3 3/9+7 6/11=10 87/99 2 3/8+6 4/5=8 12/40 ,3 3/7+4 2/3=7 2/21 4 5/6+5 5/7=9 10/13

garri49 [273]

Answer: 3 3/9+7 6/11 = 10 87/99

Step-by-step explanation:

a. 3 3/9+7 6/11 = 10 87/99

First and foremost, we need to know the lowest common multiple of 9 and 11 which is 99.

Therefore, 3 3/9 + 7 6/11 would be:

= 3 33/99 + 7 54/99

= 10 87/99

This is correct

b. 2 3/8 + 6 4/5 = 8 12/40

First and foremost, we need to know the lowest common multiple of 8 and 5 which is 40.

Therefore, 2 3/8 + 6 4/5 would be:

= 2 15/40 + 6 32/40

= 8 47/40

= 9 7/40

Since the answer gotten is 8 12/40. This is wrong.

c. 3 3/7 + 4 2/3 = 7 2/21

First and foremost, we need to know the lowest common multiple of 7 and 3 which is 21.

Therefore, 3 3/7 + 4 2/3 would be:

= 3 9/21 + 4 14/21

= 7 23/21

= 8 2/21

Since the answer gotten is 7 2/21. This is wrong.

d. 4 5/6 + 5 5/7 = 9 10/13

First and foremost, we need to know the lowest common multiple of 6 and 7 which is 42.

Therefore, 4 5/6 + 5 5/7 would be:

= 4 35/42 + 5 30/42

= 9 65/42

= 10 23/42

This is wrong as the answer gotten is 9 10/13

Therefore, the true option is

3 3/9+7 6/11 = 10 87/99

What is the zero of the function below?

Ymorist [56]

x = 1

Step-by-step explanation:

Given data: $f(x)=3 \sqrt{x+3}-6$

Recall: If f(x) = 0, then x is called the zero of the function.

To find zero of the function, take f(x) = 0.

$\Rightarrow 3 \sqrt{x+3}-6=0$

Add 6 to both sides of the equation.

$\Rightarrow 3 \sqrt{x+3}=6$

Divide both sides of the equation by 3.

$\Rightarrow \sqrt{x+3}=2$

Taking square on both sides of the equation.

$\Rightarrow(x+3)=2^{2}$

⇒ x + 3 = 4

⇒ x = 1

Hence, the zero of the function is 1.
