The answer is 9 because you solve it from left to right and 3x5 equals 15, 15 subtracted by 6 equals 9
Answer:
x = 24 , y = 19
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
2x - 8 = x + 16 ( subtract x from both sides )
x - 8 = 16 ( add 8 to both sides )
x = 24
and
2y = y + 19 ( subtract y from both sides )
y = 19
Answer: 0.75 (choice B)
=============================================
Explanation:
One way to set up the equation is to think of it like this
vertical/horizontal = vertical/horizontal
So we could say
(3.5)/(28) = x/6
Cross multiply and solve for x
3.5*6 = 28*x
21 = 28x
x = 21/28
x = (3*7)/(4*7)
x = 3/4 in fraction form
x = 0.75 in decimal form
-------------
Another possible set up equation is
28/6 = (3.5)/x
in this case I divided the horizontal sides together (28 and 6) and the vertical sides divide to form their own separate fraction as well.
Solving that equation should lead you to x = 3/4 = 0.75
Other equations are possible.

Answer:
D
Step-by-step explanation:
Hi there!
We're given the equation y=-75x-50, which represents a submarine DESCENDING towards the ocean floor, where y is the depth in feet, and x is the number of minutes the submarine is descending
Since the submarine is DESCENDING, we can immediately eliminate A and C, which talk about the submarine ASCENDING
That leaves B and D
Looking at the given equation, y=-75x-50, -75 is the slope, or rate of change, and -50 is the y intercept, or the "beginning" (where the equation will "start")
Therefore, the submarine will start at -50 feet, or 50 feet below sea level
As x is the number of minutes the submarine is descending, that means that if the submarine travels 1 minute, it will descend 75 feet (-75*1=-75), at 2 minutes, it'll descend 150 feet (-75*2=-150), and so on
So that means the submarine must be descending at a rate of 75 feet per minute
Therefore D is the correct answer
Hope this helps! Good luck on your assignment :)
