There is a 99.3 chance that neither occur cause you would add 0.3 and 0.4 together and get 0.7 then you would subtract 100 and 0.7 and get 99.3. So your answer is 99.3. Hope this helped :D
<em>multiply the numbers.</em>
4 x 6 + y = 20
<em>move constant (24) to the right side and change its sign.</em>
24 + y = 20
<em>calculate the difference and you get the answer.</em>
y = 20 - 24
y = -4
So the value of y is -4.
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:
Step-by-step explanation:
Let the dogs' ages be represented by b and m.
b + m = 16
b - m = 2
Adding these equations gives ...
2b = 18
b = 9 . . . . . . divide by 2
m = 7 . . . . . . 2 years younger than Beau
Beau is 9; Max is 7.
_____
Once you realize the above solution is generic, you can write down the answer that <em>(older)</em> Beau is half the <em>sum</em> of the given numbers: (16 +2)/2 = 9. Then Max's age is easily found, or it can be computed as half the difference of the given numbers: (16 -2)/2 = 7.
(9x - 8)(9x + 8)
9x × 9x = 81x²
9x × 8 = 72x
-8 × 9x = -72x
-8 × 8 = -64
= 81x² + 72x - 72x - 64
The 72x cancels out, so you're left with 81x² - 64.
The answer is 81x² - 64.
