Both of these problems will be solved in a similar way, but with different numbers. First, we set up an equation with the values given. Then, we solve. Lastly, we plug into the original expressions to solve for the angles.
[23] ABD = 42°, DBC = 35°
(4x - 2) + (3x + 2) = 77°
4x+ 3x + 2 - 2 = 77°
4x+ 3x= 77°
7x= 77°
x= 11°
-
ABD = (4x - 2) = (4(11°) - 2) = 44° - 2 = 42°
DBC = (3x + 2) = (3(11°) + 2) = 33° + 2 = 35°
[24] ABD = 62°, DBC = 78°
(4x - 8) + (4x + 8) = 140°
4x + 4x + 8 - 8 = 140°
4x + 4x = 140°
8x = 140°
8x = 140°
x = 17.5°
-
ABD = (4x - 8) = (4(17.5°) - 8) = 70° - 8° = 62°
DBC =(4x + 8) = (4(17.5°) + 8) = 70° + 8° = 78°
Given that the distribution of colors for plain MM andies is as follows:
<span>Colors - Purple Yellow Red Orange Green Blue Brown
Percentage - 20% 20% 20% 10% 10% 10% 10%
Suppose
one candy is taken at random from a large bag of plain MM candies, the
probability that the candy is purple of orange is given by:
P(purple candy or orange candy) = P(purple candy) + P(orange candy) = 20% + 10% = <span>30%</span></span>

2Step-by-step explanation:
I’m so confused on how to help you plz explain
To solve this question, let's divide it in parts.
Part 01: "`Product of 7 and the number"
Let's say the unknown number is "a".
So, the product of 7 and "a" is 7a.
Part 02: The sum of -8 and the product of 7 and a number.
Since "the product of 7 and a number" is 7a:
The sum of -8 and 7a is
Answer:
- 8 + 7a
