Answer:
75
Step-by-step explanation:
We have a 90 degree angle and a 15 degree angle that add up to 105. The angle that is missing can be found by doing 180 - 105 = 75 (since it's a straight line). X is vertical from the 75 degree angle, so 75 is your answer.
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable (a letter), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient.
So the terms are 9a, 4b, and 18.
hope it helps!
We have been given the truth table for three variables p, q, and r. as shown below
p q r
A T T T
B T T F
C T F T
D T F F
E F T T
F F T F
G F F T
H F F F
Now we need to find Which statements are true for rows A and E for the following statements:
p ↔ q p ↔ r q ↔ p q ↔ r r ↔ p r ↔ q
To find that we need to use table of P <-> Q as shown in picture.
We know that if both statements are true for P and Q then only P <-> Q will be true. So using that trick we see that only q<->r and r<->q are the final answer as shown in the attached picture.
Here you go!
3n-4=14
+4 +4
3n=18
(Divide both sides by 3)
n=6
Step 1: Set up a table.

Step 2: Fill in the table with information given in the question.
John is twice as old as his friend Peter. Peter is 5 years older than Alice. In 5 years, John will be three times as old as Alice. How old is Peter now?
Let x be Peter’s age now. Add 5 to get the ages in 5 yrs.
Algebra Age Problems
Write the new relationship in an equation using the ages in 5 yrs.
In 5 years, John will be three times as old as Alice.
2x + 5 = 3(x – 5 + 5)
2x + 5 = 3x
Isolate variable x
x = 5
Answer: Peter is now 5 years old.
