Answer:
4.07
Step-by-step explanation:
11 1/5 divided by 2 3/4
= 11 1/5 ÷ 2 3/4
= 56/5 ÷ 11/4
= 56/5 × 4/11
= (56*4) / (5*11)
= 224/55
= 4.07
The best estimate of 11 1/5 divided by 2 3/4 is 4.07
Answer:
y = 
Step-by-step explanation:
Hello!
The graph linked above is what is known as a "Reciprocal Graph"
A reciprocal in math is a multiplicative inverse or reciprocal for a number x.
For example the reciprocal of 1/2 is:
With this in mind we know that our graph will have the function 
Shown below is the graph of
The value of x is 8 when y = 12 if variables x and y have proportional relationship.
According to the given question.
Variables y and x have proportional relationship.
⇒ y ∝ x
Let k be the constant of proportionality.
⇒ y = kx
Also, it is given that
y = 21 when x = 14
Substitute the value of y = 21 and x = 14 in y = kx to find the value of k.
21 = k(14)
⇒ k = 21/14
⇒ k = 3/2
Therefore, the value of x when y = 12
y = kx
⇒ 12 = (3/2)x
⇒ 12 × 2 = 3x
⇒ 24 = 3x
⇒ x = 24/3
⇒ x = 8
Hence, the value of x is 8 when y = 12.

Answer:
Step-by-step explanation:
In this equation what is strange is probably using the letter a as the unknown, but this is a matter of choice we could have calle y or z for that matter. Then we will treat it ans any other equation and solve it.
-11 -5a = 6(5a+4)
-11 -5a= 30a + 24
-11 - 24 = 30a + 5a (placing the unknown a in the rght side and the numbers in the left to solve the equation)
- 35 = 35a
-35/35 = a
- 1= a
