"x" represents an unknown number, we know that 70% of x equals 63.
To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:
So the 70% of x can be calculated as:
You can simplify this expression by solving the division
Then the expression that shows you the relationship is
Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7
The value of x is 90
This is the answer 104.4285714285714
Answer:
C. (0, -3)
Step-by-step explanation:
The given system is
The point that satisfies both inequalities is the solution to the system.
When x=0 and y=-3.
We substitute into the first inequality to get:
We again substitute into the second inequality to get:
The point (0,-3) is a solution to the system of inequalities.
Answer:
y = m x + b is the standard form of a straight line
m = (y2 - y1) / (x2 - x1) = (10 - (-8)) / (-3 - 0) = 18 / -3 = -6
When x = 0 y = b from the equation for a line
y = - 8
So our equation is
y = -6 x - 8
As a check let x = -2 then
y = (-6 * -2) - 8 = 12 - 8 = 4
Check on the graph to verify that this equation holds
First I'd assume each "pizza" refers to the number of pizza pies. Each pizza pie includes 8 slices. Since there are 12 team members, and each at three, therefore 36 slices total were eaten by each of the 12 team members (12x3). Since you know that 8 slices make up a pizza pie, how many pies do you need to have at least 36 slices? The answer is 5 pies (or 40 slices). So the team ate 36/40 slices or 9/10 pizzas.
