Answer:
960
Step-by-step explanation:
You have to figure out what 1/4th of 640 is, which is 160.
It says that number is 1/6th of boys, so you multiply by the inverse.
160x6 = 960
Answer:
x = -1,-5
Step-by-step explanation:
X^2 + 3x + 5 = -3x
x^2 + 6x + 5 = 0
(x + 5)(x + 1) = 0
x = -1,-5
Answer:

Step-by-step explanation:
Given:
The given inequality is:

The given inequality has variable 'x' on both sides of the inequality.
In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.
Therefore, we could either add
on both sides or add
both sides to bring the variable terms on same side.
If we add
both sides, we get:

So, among all the given options, third option matches the above inequality.
Therefore, the first step in solving the given inequality is 
Answer:
j = 44/3
Step-by-step explanation:
j varies jointly as g and v. This can be represented mathematically as:
.............(1)
Where k is a constant of proportionality
j = 2 when g = 4 and v = 3
Substitute these values into equation (1)
2 = k * 4 * 3
2 = 12 k
k = 1/6
when g = 8 and v = 11:
j = (1/6) * 8 * 11
j = 44/3
1) Slope = 1, Y-Int = 4, 2) Slope = 2, Y-Int = -2
