abc is an isosceles triangle. Solve for x. In your final answer, include all of the necessary calculations
Answers
1. Using the Rule, sum of interior angles of a Triangle is Equal to 180:
180 - 88 = 92
2. Using the Rule that Angle A = Angle C ( since its an Isosceles triangle ) :
92 / 2 = 46
Therefore A=46 & C=46
3. Using the Rule, Angle of a Straight line is 180:
Angle of C = 46
X = 180 - 46
X = 134
Hence Solved ✌

A) How many points does There have if she has 5 cards?
B) How many points does Mark have if he has 8 cards?
C) Who has more points?
Answers
*Since each card is worth -50 points, you need to remember that a positive times a negative integer gives you a negative integer.*
Part A) Theresa has 5 cards so: 5 x -50 = -250
Theresa has -250 points.
Part B) Mark has 8 cards so: 8 x -50 = -400
Mark has -400 points.
Part C) Theresa has more points because -250 is closer to 0 on a number line.
Answer:
Negative x Positive = Negative
A) -50 x 5 = -250

At least how many schools have participated for 3 to 7 years? (4 points) 3 schools 5 schools 7 schools 8 schools
Answers
*see attachment showing the box plot
Answer:
8 schools
Step-by-step explanation:
In a typical box plot, data set are usually represented and denoted by quartiles in almost equal proportion. That is, 25% of the data set falls between the min and the Q1 value. From Q1 to median value, we have about 25%. From median to Q3, we have 25%, and from Q3 to the max, we have about 25%.
In the box plot given, we have:
Schools that have participated for at least 3 - 7 years fall within Q1 (3) and Q3 (7). Therefore, we have about 50% of the total number of schools that have spent 3 to 7 years.
No of schools that have spent at least 3 - 7 years = [tex] \frac{50}{100}*16 = 8 schools [/tex]

Answers
Answer:
k = -1
Step-by-step explanation:
-3(k-8)-(k+5)=23
Distribute
-3k +24 -k-5 = 23
Combine like terms
-4k +19 = 23
Subtract 19 from each side
-4k +19-19 = 23-19
-4k = 4
Divide by -4
-4k/-4 = 4/-4
k = -1
Answer:
k = -1
Step-by-step explanation:
Use the distributive property to eliminate parentheses. That property tells you that the outside factor multiplies each term inside parentheses:
-3(k -8) -(k +5) = 23
-3k -3(-8) -k -(+5) = 23
-3k +24 -k -5 = 23 . . . . simplify
-4k +19 = 23 . . . . . . . . . collect terms
-4k = 4 . . . . . . . . . . . . . subtract 19 from both sides
k = -1 . . . . . . . . . . . . . . . divide both sides by -4

The rule for manipulating equations is, "any operation performed on one side of the equation must also be performed on the other side." Operations include addition, subtraction, multiplication, division, application of a function. Using the distributive property and collecting terms are ways to simplify equations that don't affect the truth of the equal sign (if those are done correctly).
In general, you make use of inverse operations to undo the operations you don't want. The goal is to get the variable by itself on one side of the equal sign.

The area of the lake is actually 182 square miles 1 inch represents one side 3 miles long the other side is also 3 miles. 3×3=9 square miles. 1 Square Inch on the map represents 9 Square Miles.Step-by-step explanation:
The actual area of the lake is 162 square miles if the map that was created using a scale of 1 inch : 3 miles.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object, is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
We have:
A map that was created using a scale of 1 inch : 3 miles
1 inch = 3 miles
1 square inch = 9 square miles
The area of the lake = 18 square inches
The actual area of the lake = 18×9 = 162 square miles

Let's apply the given formula:
A = (1/2)·B·H
The base of this polygon (in this case, the triangle) is B
B = X² - 2X + 6
The height of this polygon is H and is H
H = X + 4
Applying these values (B and H) in the given formula.....

An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b. This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Answers
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
Thus, answer is base=3.1 cm

In step 1, the slope of the line should be One-half
Answer:
y = (1/2)x + 4
Step-by-step explanation:
As we move from the point (-2, 3) to the point (4, 6), x (the 'run') increases by 6 and y (the 'rise')increases by 3. Therefore the slope of the line connecting the two points is m = rise / run = 3/6, or m = 1/2.
We want the slope-intercept form of the equation of this line. The basic form is y = mx + b. Arbitrarily choosing to use the point (4, 6) and using m = 1/2, we get:
6 = (1/2)(4) + b, or b = 4.
Then the desired equation is y = mx + b, or y = (1/2)x + 4

Bottlenose Dolphin: 40 = 20 miles per hour
King Penguin: 40 = 5 miles per hour
Swordfish: 60 miles per hour
Answers
Answer:
It takes the Dolphin 2 hours for swimming 40 miles. The penguin takes 8 hours and the swordfish will take 2/3 of an hour, which is 40 minutes to travel 40 miles.
Step-by-step explanation:
Given :
The bottlenose dolphin travels 40 miles in 2 hours. Or it takes 20 miles in 1 hour.
Now, dividing the distance by unit rate given in the question:
40/20=2 hours
40/5=8 hours
40÷60= 2/3 hour
Therefore,
- the dolphin takes 2 hours for swimming 40 miles.

Answers
The correct answer would be options (A), (D), and (E)
x + y = 28
28 - y = x
28 - x = y
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The first column, yards of red fabric, x, has the entries 1, 2, 3, 4.
The second column, yards of blue fabric, y, has entries 27, 26, 25, and 24.
Sophie is buying fabric to make items for a craft fair.
when substitute x = 1 and y = 27
⇒ x + y = 1 + 27 = 28
So the equations model the total yards of fabric Sophie will buy as
⇒ x + y = 28
⇒ 28 - y = x
⇒ 28 - x = y
Hence, the correct answer would be options (A), (D), and (E)

Answer:
y = 6x
Step-by-step explanation:
Choose two points on the graph of this line for the purpose of calculating the slope (rise/run). One such point is (0, 0), which is a good choice because both x and y are exactly zero there. Another point would be (16, 96), as the line goes through this point exactly.
Then the slope is m = rise / run = 96/16 = 6.
We'll use y = mx + b, with x = 0 and y = 0, learning immediately that b must be 0.
Thus, the equation of this graph is y = mx + b => y = 6x, which is a proportional relationship.
Hi Dear Brainly User!
Answer: y = 6x
y and x:
12 - 2
24 - 4
36 - 6
.......
If we want to find m, we divide y by x. (m: the slope)
m = y/x = 12/2 = 24/4 = 36/6 = ... = 6
We use for find the y:
y = ax + b
Then, we write y = 0 and x = 0 on the formula.
And we find the b is 0.
If we multiply the slope by x, we get y.
y = 6*x = 6x
