Answer:
The man is 27 years old.
Step-by-step explanation:
You can create a system of equations.
Let x = the age of the man
Let y = the age of his son
You can create the following equations based on what was given in the problem:
1. x = y + 18
2. (x - 3) = 4(y - 3)
You can simplify the second equation:
x - 3 = 4y - 12
x = 4y - 9
Then, solve the system of equations:
x = y + 18
-
x = 4y - 9
____________
0 = -3x + 27
The son's age is 9, therefore the father is 27 years old.
149 pennies.
Very likely: extremely likely, highly reasonable, almost certainly.
Considering the above definitions of "very likely", a jar of 150 coins, 149 of them being pennies, would satisfy each definition given for "very likely".
Almost certainly indicates that there is a possibility that you'd choose a coin that's not a penny, so a jar of 150 coins which are all pennies doesn't satisfy this definition.
Answer:
so u take all angles and add them then find the value of x by dividing it by 180degrees
Answer:
40/48
Step-by-step explanation:
10*4=40
12*4=48
Step-by-step explanation:
8. 120° - Obtuse angle
9. 40° - Acute angle
10. 180° - Straight angle
11. 90° - Right angle
