Answer:
25 meters.
Step-by-step explanation:
Given in the question that,
Initial depth of the submarine = 8 meters
After the order of the captain, the submarine was made to dive another 17 meters.
So, the final cruising depth of the submarine can be calculated by <u>adding the initial depth of the submarine and the depth further increased upon the order of the captain</u>.
Thus, final cruising depth of the submarine = 8 + 17 = 25 meters.
Answer:
(x - y)(j - s).
Step-by-step explanation:
jx + sy - sx - jy
= jx - sx + sy - jy
= x(j - s) - y(j - s)
= (x - y)(j - s).
Answer:
112, 119 and 126.
Step-by-step explanation:
Let the consecutive multiples of 7 be 7n, 7(n+1) and 7(n+2) where n is an integer, then:-
7n + 7n + 7 + 7n + 14 = 357
21n + 21 = 357
21(n + 1) = 357
n = (357/21) - 1
n = 17 + 1 = 16.
So the numbers are 7*16 = 112, 7*17 = 119 and 7*18 = 126.
