Answer:
Choice 3. -4x-3<13
Step-by-step explanation:
First, you will use process of elimination and cross out any obvious wrong answers. You can see that the symbol would not be flipped yet so the "<" would be pointing to less than. That eliminates choice 1 and 4. Now, You can observe the 3rd step and see that -4x<16, to get that, you would need a "-4x" in the equation. Number 2 is 2x so that can't be right. Therefore, the answer is choice 3. This simple process of elimination and looking for clues will help you greatly in multiple choice problems instead of solving it the hard way.

Use the mean formula to write an equation to estimate x , the number of students who attended the fourth meeting.
c. Solve the equation in part (b) to find the number of students who attended the fourth meeting.
answer gets brainliest
Answers
The required formula to find the number of students who attended the fourth meeting is 80 = 56 + x
Using the mean formula, the number of students who attended the fourth meeting is 24
Formula to obtain the mean :
Mean = ΣX/ n
X = number of students that attended each meeting
n = number of meetings
X = meeting 1 + meeting 2 + meeting 3 + meeting 4
n = 4
Mean = 20
Let number of students who attended 4th meeting = x
Mean = ΣX/ n
20 = (18 + 21 + 17 + x) / 4
80 = 56 + x
x = 80 - 56
x = 24
Hence, 24 students attended the fourth meeting.

When are two geometric shapes considered similar?
Answers
Answer:
hope this helped :)
Step-by-step explanation:
Sometimes, two similar or congruent objects may be regarded as having a different shape if a reflection is required to transform one into the other. For instance, the letters " b " and " d " are a reflection of each other, and hence they are congruent and similar, but in some contexts they are not regarded as having the same shape.
Answer:

the width of rectangle is 2w, and the length is (w+5). the perimeter is 40 inches. what are the measurements of the rectangle?
Answers
Width = 2w , Length = w+5 , perimeter = 40
Perimeter of rectangle = 2 (Length + Width)
P= 2 (L + w)
40 = 2 [ (w+5) + (2w) ]
40 = 2 ( 3w+5)
40= 6w +10
6w= 40 – 10
6w= 30
w = 30/6
w = 5
Width = 2w = 2(5) = 10
Length = w + 5 = 5+5 = 10

Convert 625 km per 4.33 hours (km/hr) into meters per second (m/s)
Answers
Answer:11.1374847 Meter per second
Step-by-step explanation:
km / hr
/ = divide
To solve this question, we'll begin by converting 625 km to m. This can be obtained as follow:
1 km = 1000 m
Therefore,
625 km = 625 × 1000
625 km = 625000 m
Thus, 625 km is equivalent to 625000 m.
Next, we shall convert 4.33 hours to second. This can be obtained as follow as follow:
1 h = 3600 s
Therefore,
4.33 h = 4.33 × 3600
4.33 h = 15588 s
Thus, 4.33 h is equivalent to 15588 s.
Finally, we shall convert 625 km per 4.33 hours to m/s
625 km = 625000 m
4.33 h = 15588 s
625 km per 4.33 hours =?625 km per 4.33 hours = 625000 m / 15588 s
625 km per 4.33 hours = 40.09 m/sTherefore, 625 km per 4.33 hours is equivalent to 40.09 m/s

A drawing class was assigned a final project where students had to choose one art medium and one subject. The teacher kept track of the types of projects submitted.
The probability that a student used chalk is 0.3, the probability that a student chose to draw a plant is 0.6, and the probability that a student used chalk and chose to draw a plant is 0.2.
What is the probability that a randomly chosen student used chalk or chose to draw a plant?
Answers
Using probability concepts, it is found that: 0.7 = 70% probability that a randomly chosen student used chalk or chose to draw a plant.
-----------------------------
I am going to treat the probabilities of these events as Venn probabilities, stating that:
Probability A: student used a chalk.Probability B: student chose to draw a plant.-----------------------------
0.3 probability of a student using a chalk, thus [tex]P(A) = 0.3[/tex]0.6 probability that the student chose to draw a plant, thus [tex]P(B) = 0.6[/tex]0.2 probability of both, thus [tex]P(A \cap B) = 0.2[/tex].-----------------------------
The probability of chalk or plant is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
From the bullet points:
[tex]P(A \cup B) = 0.3 + 0.6 - 0.2 = 0.7[/tex]
0.7 = 70% probability that a randomly chosen student used chalk or chose to draw a plant.

Objective; Translating points
A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.
Algebracially:
[tex](x + h)[/tex]
where h is the amount of units we move right or left
and
[tex](y + k)[/tex]
where k is the amount of units we move up or down
For 1. We are asked to translate the figure 3 units up and 7 units to the left.
7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is
Our new coordinates
E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).
2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.
So our new coordinates is
T' (1,3)
U' (4,3)
V'(4,5)
W'(1,5)

can anyone help? please
Answers
Step-by-step explanation:
BCD = 180- 100 = 80
the opposite angles of a parallelogram are of equal measure
SO DAB = X = 80
The sum of all parallelogram angles = 360
360 - 160 = 200
200 equals the measure of angle ADC + ABC
ABC = ADC
200 = 2ABC
ABC = 100
ADB = DBC = 30
Y = 100 - 30 = 70
another way to find y is using the rule that says that the sum of the triangle ADB angles = 180
180 = 80 + 30 + y
y = 70
