Answer:
D. 112°
General Formulas and Concepts:
A line is always 180°.
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Set up equation
m∠ABD + m∠DBC = m∠ABC
(3x + 10) + (2x) = 180°
Step 2: Solve for x
Combine like terms: 5x + 10 = 180Subtract 10 on both sides: 5x = 170Divide 5 on both sides: x = 34Step 3: Find m∠ABD
m∠ABD = 3x + 10
Substitute: m∠ABD = 3(34) + 10Multiply: m∠ABD = 102 + 10Add: m∠ABD = 112°Related Questions

the cost (in dollars) of a custom made t shirt is represented by 0.75n + 9.99, where n is the number of words in the design. write and interpret a simplified expression that represents the cost of 12 t shirts
Answers
Answer:
t=9.48n+119.88
Step-by-step explanation:
where t is the total cost of 12 t-shirts, and n is the number of words in the design
0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design
t=12(0.75n+9.99)
where t is the total cost of t-shirts, and n is the number of words in the design
When simplified, this becomes t=9.48n+119.88

You know: 13 + 7 = 20. Therefore: 13 + 7 + 2 = 20 + 2. Which Property of Equality was illustrated?
A. Subtraction Property of Equality
B. Multiplication Property of Equality
C. Division Property of Equality
D. Addition Property of Equality
Answers
Answer:
Addition Property
Step-by-step explanation:
Because since there are the plus sign there is no x - or a ÷sign so its Addition Property
13 + 7 = 20 ⇒ 13 + 7 +2 = 20 + 2 represents addition property of equality.
What is Equality ?
" Equality means representation of any two quantities using mathematical expression with the sign of 'equals to'."
According to the question,
Given,
13 + 7 = 20
Add '2' both the side of the given equality we get,
⇒ 13 + 7 + 2 = 20 + 2
Add both the sides represents addition property of equality.
Hence, Option(D) is the correct answer.

45% of the students who take part in a creative writing competition are boys. If 135 boys take part in the competition, find the total number of students who take part in the competition
Answers
Answer:
300Step-by-step explanation:
let the total number of students be x
45% of x is 135
that is
=(45/100)*x=135
0.45x=135
x= 135/0.45
x= 300students
Therefore the total number of students is 300

Step-by-step explanation:
By steps in the image:
Step 1:
To eliminate, you need one of the coefficients to be the same in both equations. We will use the term "-6x" found in the first equation.
To get this, multiply the entire second equation by 6 and simplify using the distributive property. The new equation is:
[tex]6x-6y=54[/tex]
Step 2:
Now you need to subtract the first equation and the new version of the second equation. By doing this, the "-6x" in both equations will cancel each other out.
Step 3:
Solve for x in the given equation by:
Dividing both sides by -14Simplify the value of x by dividing top and bottom by 2Step 4:
Solve for y by:
Substitute the value of x into the second equationMultiply both sides of the equation by 7Add 2 to both sides of the equationDivide both sides of the equation by -7Solution:
[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

Answer:
Part 1: 61 degrees Part 2: 90 degrees
Step-by-step explanation:
m<a = 180 - m<b - m<c - 29
m<c = 29
m<b = 90-29
m<b = 61
m<a = 180 - 61 -29 -29
m<a = 61 degrees
m<c + m<b = 29 + 61
m<c + m<b 90 degrees

a local hamburger shop sold a combined total of 750 hamburgers and cheeseburgers on tuesday there were 50 more cheeseburgers sold than hamburgers how many hamburgers were sold on tuesday
Answers
Answer:
350 hamburgers
Step-by-step explanation:
x = hamburgers
y = cheeseburgers
x + y = 750
y = x + 50
Using substitution:
x + (x + 50) = 750
2x + 50 = 750
2x = 700
x = 350
y = 350 + 50 = 400
