Answer:
80
Step-by-step explanation:
We can start of with Junior's age. Then if dad is twice as old as Junior, then we add 2 parts and get 3 parts. Then Gramps is twice as old as Dad so we add 4 parts and get 7 parts. Now we divided 140 by 7. We get 20. This is Junior's age. By looking at that, we know Dad is 40, and Gramps is 80.
Gramps is 80 years old.

Step-by-step explanation:
Answer:
“the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.
Step-by-step explanation:
Let us breakdown and translate the word expression into an algebraic expression.
The sum of 3c and 8 is algebraically represented as:
⇒ 3c + 8
Thus, “the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.
Answer:
D
Step-by-step explanation:
cos 30 = 9/x
x = 9/(
) = 6
(6)² - 9² = x²
x² = 27
x = 3
