Answer:
s = 17
Step-by-step explanation:
17 = 4(s - 14) - (-5)
distribute the 4
17 = 4s - 56 - (-5)
combine like terms
17 = 4s - 56 + 5
17 = 4s - 51
add 51 to both sides
68 = 4s
divide by 4
68/4 = 17
s = 17
Answer:
The value of 
- 
is 3 ⇒ 2nd
Step-by-step explanation:
The dimensions of any matrix are (m × n), where
- m is the number of its row
- n is the number of its column
Ex: Matrix A of dimensions (2 × 3) has 2 rows and 3 columns, where
means the element in the 1st row and 1st column
means the element in the 1st row and 2nd column
means the element in the 1st row and 3rd column
means the element in the 2nd row and 1st column
means the element in the 2nd row and 2nd column
means the element in the 2nd row and 3rd column
Now lets solve the problem
∵ The matrix B has 3 rows
∴ m = 3
∵ The matrix B has 4 columns
∴ n = 4
∴ The dimensions of matrix B are (3 × 4)
∵ means the element in the 2nd row and 4th column
∴ = 9
∵ means the element in the 3rd row and 2nd column
∴ = 6
- Find the value of -
∵ - = 9 - 6
∴ - = 3
Answer:
a. Ryan 70mph. Janelle 65mph.
b. 4 hours and 48 minutes.
Step-by-step explanation:
a. Ryan 245/3.5=70 mph. Janelle 260/4=65 mph.
b. If Janelle drives 575 miles with the speed of 65 mph, in total it would take her 575/65=8.8 hours, which is 4.8 hours more than 4 hours. (0.8 hours is 48 minutes).
