3 ft is less than 21 ft
(if you ment 21 inches 3ft=36 inches so if you ment that 3 ft would be larger in that case)
Hello!
Okay so our starting point is - 1,260 feet
Now it is descending (-) 5 ft per minute for 12 minutes
So we multiply -5 (negative because it is descending) by 12
-5 x 12 = -60
So now we add -60 to -1,260
This would be -1,320
So the submarine's new position in relation to the sea level is -1,320
Hope this helped. Have a great day!
STEP 1:
Divide the length of the ribbon by the size of the pieces.
12 inches= 1 foot
= 9 ft ÷ 15 inch pieces
convert ft to inches
= (12)(9) ÷ 15
= 108 ÷ 15
= 7.2 pieces from one roll
STEP 2:
multiply the number of pieces that can be cut from one roll by the number of rolls
= 7.2 pieces * 5 rolls
= 36 pieces total from 5 rolls
ANSWER: The greatest number of 15-inch pieces that can be cut from five 9-foot rolls is 36.
Hope this helps! :)
Third option.
Use y = mx + b (slope-intercept form) to get
y = (1/3)x + b.
Then plug in the point (1,-2) for x and y to figure out b...
-2 = (1/3)(1) + b
-2 - 1/3 = b, so b = -7/3
Now you have y = (1/3)x - 7/3. Convert to standard form by multiplying each term by 3 to get
3y = x - 7. Then move the 3y to the other side to get 0 = x - 3y - 7
Answer:
5x
Step-by-step explanation:
If the blank were to be occupied with 5x there would be no solutions
Observe...
5x - 8 = 5x + 2
* subtract 5x from each side *
5x - 5x cancels out
5x - 5x cancels out
we're left with -8 = 2
which is not true
Hence if the blank = 5x the equation will have no solution
