A -3
B -1
C о
D 4
Answer:
D
Step-by-step explanation:
Solving the inequality
- 3x + 5 > 4 ( subtract 5 from both sides )
- 3x > - 1
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative value.
x < [tex]\frac{1}{3}[/tex]

-3x-5=16
what is x in the equation
Answer:
x=−7
Step-by-step explanation:
Step 1: Add 5 to both sides.
−3x−5+5=16+5
−3x=21
Step 2: Divide both sides by -3.
−3x/−3=21/−3
Answer:
x = -7
Step-by-step explanation:
Hello.
I can help.
To solve algebraic equations all you need to do is get rid of everything on the side of the x except the x.
Lets look at your problem.
-3x - 5 = 16
An important thing to note is we are going to get rid of things on the left side of the = by doing the opposite of what they're doing.
If it is addition we do subtraction
If it is division we do multiplication
and so on.
ALSO
Whatever we do on the left side of the = we must do the same thing to the number on the right.
Now, let us start trying to solve this.
You always want to start with the number that is alone without the variable / letter.
So :
-3x - 5 = 16
Since it is -5 lets add 5 to make it 0 and get rid of it.
-3x - 5 = 16
+5 +5
(Remember to do it to the other side of the = too)
Now we have :
-3x = 21
Now we want to get rid of the 3 attached to the x. And since these two are multiplying we need to divide the -3 by itself to make it 1. Since one number divided by itself is 1.
So like this :
-3x = 21
/-3 /-3
NOTE : When you are dividing or multiplying negative numbers there is an important key to be aware of. Here is a short key to go off of :
- x - = +
- x + = -
So a negative times a negative will be a positive.
While a positive times a negative, the negative will over ride the positive and the answer will be negative.
Going back to the equation, here is what we do :
-3x / -3 = +x (Not negative)
And :
21 / -3 = -7 (Is negative)
So now our equation is :
x = -7
And this is our final answer.
I hope this helped.

In a school contest, each student draws a number from 1 to 5 out of a large basket. The outcomes are shown in the table below.
Number Drawn 1 2 3 4 5
Times Drawn 83 79 88 72 85
Based on the data, what is the expected probability of drawing a 3?
Answer:
88/407
Step-by-step explanation:
The required, based on the data given, the expected probability of drawing a 3 is approximately 0.216 or 21.6%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
To find the expected probability of drawing a 3, we need to calculate the total number of times any number was drawn and the number of times a 3 was drawn:
Total number of times any number was drawn = 83 + 79 + 88 + 72 + 85 = 407
The number of times a 3 was drawn = 88
The probability of drawing a 3 is then the number of times a 3 was drawn divided by the total number of times any number was drawn:
Probability of drawing a 3 = 88/407 ≈ 0.216
Therefore, based on the data given, the expected probability of drawing a 3 is approximately 0.216 or 21.6%.

In a triangle, the measure of the first angle is 24 degrees more than the measure of the second angle. The measure of the third angle is four times the measure of the second angle. If the total number of degrees in a triangle is 180, what is the measure of the largest angle?
26 degrees
50 degrees
104 degrees
136 degrees
Here goes the answer. Hope it helps.
Measure of largest angle in a triangle is equals to 104 degrees.
What is triangle?" Triangle is a 2 dimensional geometrical figure which has three sides and three vertices. Sum of all the angles of triangle is equals to 180°."
According to the question,
x represents the measure of first angle
y represents the measure of second angle
z represents the measure of third angle
Situation 1: First angle is 24 degree more than second angle , it represents the equation:
x = 24 + y ____(1)
Situation 2: Third angle is four times the measure of second angle, it represents the equation:
z = 4y ___(2)
Situation 3: Total number of degree in a triangle is 180, it represents the equation :
x + y + z = 180° ____(3)
Substitute the value of (1) and (2) in (3) we get,
24 + y + y + 4y = 180°
⇒ 6y + 24 = 180°
⇒ 6y = 180 - 24
⇒ 6y = 156
⇒ y = 26degrees
Therefore,
x = 24 + 26
= 50 degrees
z = 4 × 26
= 104 degrees
Hence, measure of largest angle in a triangle is equals to 104 degrees.

Does the equation 5(x – 3) = 10x–15 have one solution, infinitely many solutions, or no solution?
Answer:
infinitely many solutions
Step-by-step explanation:
The equation 5(x - 3) = 10x - 15 has one solution, which is x = 0.
Let's simplify the given equation:
5(x - 3) = 10x - 15
Distribute the 5 on the left side:
5x - 15 = 10x - 15
Now, let's isolate the variables on one side by subtracting 5x from both sides:
-15 = 5x - 15
Next, add 15 to both sides:
0 = 5x
Divide both sides by 5:
0/5 = 5x/5
0 = x
Therefore, the equation simplifies to 0 = x. This means that x is equal to 0.
So, the equation 5(x - 3) = 10x - 15 has one solution, which is x = 0.

the owner of a pet shop buys budgie bells in packs of 30 bells. she pays 12p per bell. She sells 3/5 of the bells for 50p each and the rest for 40p each. How much profit does she make on the whole pack of budgie bells?
Answer: 1020p
Step-by-step explanation:
The total cost of the bells will be:
= 12p × 30 = 360p
She sells 3/5 of the bells for 50p each. This will be:
= (3/5 × 30) × 50
= 18 × 50p
= 900p
She sells the remaining 2/5 for 40p each. This will be:
= (2/5 × 30) × 40
= 12 × 40
= 480p
Then, total revenue will be:
= 900p + 480p
= 1380p
Profit = Revenue - Cost
= 1380p - 360p
= 1020p
