Answer:

x = 2

Step-by-step explanation:

12/7.5 = 1.6

x+6/2x+1 = 1.6

to find the value of x :

$\frac{x+6}{2x+1} = \frac{1.6}{1}$

x + 6 = 3.2x + 1.6

x - 3.2x = 1.6 - 6

- 2.2x = - 4.4

- x = - 4.4/2.2

- x = - 2

x = 2

The graph relates the number of gallons of white paint to the number of gallons of red paint Jess used to make the perfect pink.

Effectus [21]

Answer:

y = $\frac{1}{4}x$

Step-by-step explanation:

Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.

Let the number of gallons of white paint required = x

and number of gallons of red paint required = y

y ∝ x

y = kx [k = proportionality constant]

Since a point (4, 1) lies on this line,

1 = 4k

k = $\frac{1}{4}$

Therefore, equation that describes the relationship will be,

y = $\frac{1}{4}x$

Given n(A) = 1300, n(A U B) = 2290, and n(A n B) = 360, find n(B).

Stels [109]

Answer:

n(B) = 1350

Step-by-step explanation:

Using Venn sets, we have that:

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

Three values are given in the exercise.

The other is n(B), which we have to find. So

$n(A \cup B) = n(A) + n(B) - n(A \cap B)$

$2290 = 1300 + n(B) - 360$

$940 + n(B) = 2290$

$n(B) = 2290 - 940 = 1350$

n(B) = 1350
