What’s the answer for a, and b, and how would you solve it?
Answer:
a) negative
b) -7/6
Step-by-step explanation:
The x value increased, but the y value decreased so the line goes down and has a negative slope
(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line
(4-(-3))/(-1-5)=7/-6
how to do this problem:5(x-2)+(-9)=-7(1-x)

A scale of a living room is shown below. The scale is 1:40.
Show your work to determine the area of the room in square feet.
PLEASE EXPLAIN!
Answer:
24^2 inc
Step-by-step explanation:
The room is in a rectangular shape and to calculate the area of it we multiply width and length :
4 x 6 = 24^2 inches
Please help, it’s linked to polygons
Answer:
It has 15 sides.
Step-by-step explanation:
( n-2 ) × 180 / n = 156
180n - 360 = 156n .
180n - 156n = 360
24 n = 360
n = 360/24 = 180/12 = 90/6 = 15 .
n = 15 sides.
Solve for x. Round to the nearest tenth, if necessary.
Find the area of the circles with : (vi) circumference = 66cm
Answer:
Area = A = 65.999999999997 cm
Step-by-step explanation:
Circumference = 66 cm
Circumference = 2πr
So 2πr = 66 cm
r = 66/2π =10.509554140127
Area of circle = πr² = 3.14(10.509554140127)²
Area = A = 65.999999999997
On a multiple-choice test with five possible answers for each question, what is the probability of answering a question correctly if you make a random guess? (write your answer as a decimal).
The probability of answering correctly if you make a random guess is:
P = 1/5 = 0.2
How to find the probability for a random guess?If you make a random guess, then you have no idea of which could (or couldn't) be the correct answer. Thus, all the 5 options have the exact same probability of being the correct one.
From this, the probability of answering correctly the question is given by the quotient between the number of correct answers (we assume is only one) and the total number of options (5).
So the probability is:
P = 1/5 = 0.2

Answer: BXC =70°
Step-by-step explanation:
XBC= isosceles so XBC=XCB
XBC=55° (isosceles triangle)
BXC+XBC+XCB=180° (angles in a triangle =180°)
BXC=180°- (55°+55°)
BXC=180°-110°
BXC=70°
Andy, Bert, and Charles have 20 pieces of chocolate. Some of the chocolates have nuts, some are plain, and some are filled with caramel (they are split in a ratio of 1:2:2, respectively). Neither Andy nor Charles can eat nuts, and Charles will always take caramels over plain chocolates if he can (the others are indifferent to plain or caramels). If Andy, Bert, and Charles split the chocolates among themselves in a ratio of 3:1:1, respectively, in a way that makes each person as happy as possible, how many pieces of chocolate with caramel does Andy receive?
Answer: 4
The ratio in which the chocolates are divided into types can be seen as splitting the chocolates into 1+2+2 = 5 equal parts. Since there are 20 chocolates, each part corresponds to 20/5 = 4 chocolates. Thus, there are 1*4=4 chocolates with nuts, 2*4=8 plain chocolates, and 2*4=8 chocolates with caramel. Now, the three boys are dividing the chocolates into 3+1+1 = 5 equal parts. Thus, each part again corresponds to 4 chocolates. So, Andy will receive 3*4=12 chocolates, Bert will receive 1*4=4 chocolates, and Charles will receive 1*4=4 chocolates. Because neither Andy nor Charles can eat nuts, and there are four chocolates with nuts, and Bert receives four chocolates, Bert must take all of the chocolates with nuts. Charles receives four chocolates total, and, since he prefers caramel, he will take four of the eight caramels. This leaves eight plain chocolates and four caramels to make up Andy's twelve chocolates. Thus, Andy receives 4 pieces of chocolate with caramel.

What is 1 19/100 as a decimal?
Answer: 1.19
Step-by-step explanation: To convert this mixed number (fraction) to a decimal just follow these two steps:
Step 1: divide numerator (19) by the denominator (100): 19 ÷ 100 = 0.19
Step 2: add this value to the the integer part: 1 + 0.19 = 1.19. So,
1 19/100 = 1.19
Rounded values:
1 19/100 = 1 rounded to 0 decimal places
1 19/100 = 1.2 rounded to 1 decimal place1

I need help with problem 11
Answer:
x = 68
Step-by-step explanation:
The formula for calculating the sum of interior angles of a polygon is: (n - 2) x 180° (where n is the number of sides)
This polygon has 5 sides, so the sum of the interior angles:
(5 - 2) x 180° = 540°
To find x, add together all the angle expressions, equate to 540 and solve for x:
U + V + W + Y + Z = 540
(x - 8) + (3x - 11) + (x + 8) + x + (2x + 7) = 540
Gather like terms: x + 3x + x + x + 2x - 8 - 11 + 8 + 7 = 540
Combine like terms: 8x -4 = 540
Add 4 to both sides: 8x = 544
Divide both sides by 8: x = 68
