There are a total of 68 cars in the parking lot (sum of all values on the table).
Selecting blue OR a chevy, means all blue and all chevies are valid choices...there are 7+9+8+7+5 (blue cars and chevy cars) = 36:
36/68 = 9/17
Selecting blue AND a chevy - There are 8 blue chevies:
<span>8/68= </span>2/17
GIVEN that the car is blue means we're <em>only selecting from </em>the 7+9+8 = 24 blue cars on the lot which are chevies...and there are 8 blue chevies:
8/24 = 1/3
Answer:
13 - 17
Step-by-step explanation:
Using the rule
× = a
Each term in the second factor is multiplied by each term in the first factor, that is
2 ( - 9 ) + 1 ( - 9 )
Distribute both parenthesis
= (2 × 11) - 18 + - 9
= 22 - 17 - 9
= 13 - 17
Answer:
3rd option
Step-by-step explanation:
Given
y + 
= 6 ( multiply through by 4 to clear the fraction
4y + 3 = 24 ( subtract 3 from both sides )
4y = 21 ( divide both sides by 4 )
y = 
= 5 
To solve this, follow these steps:
5x + 27 = 9 (x+3) - 4x
Distribute the 9 within the parenthesis:
5x + 27 = 9x + 27 - 4x
Then combine like terms:
5x + 27 = 5x + 27
These two then cancel each other out completely.
This is an identity because an identity in math is when both equations equal each other, which is shown above.
Hope this helps!
Answer:
Step-by-step explanation:
A=2i+3j+4k
B=i-2j+3k
Sum of the vectors:
A + B = 2i+3j+4k + i-2j+3k = 3i + j + 7k
Direction of the sum of the vectors:
