Which inequality is true is x=4?
-25x>100
-25x _< 100
25x < 100
25x _< 100
Step-by-step explanation:
One inequality could be x > 3. So when x = 4 this is true because 4 is greater than 3.

u < 28
Step-by-step explanation:
To find if a value works for an inequality, one has to substitute in the value and simplify. If the resulting equation is true, then the value is a part of the solution set of the inequality.
When simplifying an inequality, one must follow all the same rules as simplifying an equation. The only difference is that when one multiplies or divides by a negative number one must flip the inequality sign for the inequality to remain true. In this case, this rule won't come into play.

Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?
Two apples are split among 3 people. How much of an apple does each person receive?
Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?
Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?
Answer:
The first, second, and fourth questions.
Step-by-step explanation:
None of these result in an answer of 23, so I'm assuming that you meant 2/3.
"Two gallons of water are needed to fill 3 fish tanks of equal size. How many gallons of water are required for each tank?"
2 gallons divided between 3 tanks is 2 divided by 3, so 2/3.
"Three cats share 2 cans of tuna. How much of a can does each cat receive?"
2 cans divided between 3 cats - it's the same as the above problem, just with cats and tuna cans instead of tanks and gallons of water. Each cat gets 2/3 of a can.
"Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?"
2 bags divided between 5 parrots would be 2/5 of a bag for each parrot.
"Two apples are split among 3 people. How much of an apple does each person receive?"
Two apples split among 3 people - like the first 2 questions, this also equals 2/3.
"Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?"
Three dogs EACH drink 2 cups of water means that the answer is 2*3=6 cups.
"Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?"
Three cupcakes are split between 2 children - they will each get 3/2 of a cupcake, or 1 1/2.

Tell whether (4, 27) is a solution of y=3x+15
Answer:
Yes
Step-by-step explanation:
We have two properties for our question :
(4, 27)
y = 3x + 15
We are being asked whether the point (4, 27) is a solution of y = 3x + 15
So how do we figure this out? Well, what we have to know first that (4, 27) represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.
y = 3x + 15
y = 27 and x = 4
27 = 3(4) + 15
27 = 12 + 15
27 = 27
Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

Raina bought 6 CDs that were each the same price. Including sales tax, she paid a total of $73.20. of that total, S7.80 was tax. What was the price of each
before tax?
Answer:
$4.40
Step-by-step explanation: First you divide 73.20 by 6 to get 12.2. Thats how much each costs with tax. Then you have to take tax off so 12.2-7.80=4.4. So $4.40.

Answer:
23
Step-by-step explanation:
the angles are equal to each other so we use the equation
6x-7=9x-22 and solve for x
step 1 subtract 6 from each side
-7=3x-22
step 2 add 22 to each side
3x=15
step 3 divide each side by 3
x=5
then to find the angle abd we plug in 5 to 9x-22
9x5=45
45-22=23 so angle abd=23
hope this helps (:

What is the y-intercept of the line?
(0,1) or 1
Solution:The y-intercept of a line is the point where the graph touches the y-axis.The y-intercept is usually written as (0,b) where b stands for the y-intercept.Since the given graph touches the y-axis at (0,1), the y-intercept of the line is (0,1) or 1.Hope it helps.

Find the ratio in which the point P(11, y) divides the line segment
Joining the points A(15,5) and B(9, 20). Also, find the value of y.
Answer:
ratio: 2:1
y = 15
Step-by-step explanation:
The ratio would be 15-11:11-9 = 4:2 = 2:1
This is because you can subtract the x values of the two points with 11.
To find the value of y:
Figure out the equation of the line between the two points by putting it in the form y = mx + b where m is the slope and b is the y-intercept.
To find the slope, use change in y/change in x so:
20 - 5/9-15 = 15/-6 = 5/-2 = -2.5
That means the slope is -2.5, so you have:
y = -2.5x + b
since you know the point (15, 5) is a solution, you can plug x = 15 and y = 5 into the equation:
5 = -2.5 * 15 + b
5 = -37.5 + b
b = 42.5
The equation is: y = -2.5x + 42.5
Then, plug in x = 11 into the equation:
y = -2.5*11 + 42.5
y = -27.5 + 42.5
y = 15
