The answer is B, 30 x 5 The answer is reasonable. Ryder is correct. It reasonable because if 25 x 5 is 125, then 30 x 5 won't be too much to be unreasonable. 30 x 5 is 150, therefore it is only 25 windows higher, so it is reasonable. Hope this helps! :)
Isolate the y for both questions. Note that what you do to one side, you do to the other. Do the opposite of PEMDAS.
First question: x - 5y ≥ 3
First, subtract x from both sides
x (-x) - 5y ≥ 3 (-x)
-5y ≥ -x + 3
Divide -5 from both sides. Note that when you divide by a negative number, you flip the equation.
(-5y)/-5 ≥ (-x + 3)/-5
y ≤ (-x + 3)/-5
y ≤ x/5 - 0.6

Do the same for the second one. Subtract x from both sides
x + y < 0
x (-x) + y < 0 (-x)
y < - x

12:45. Quarter past twelve is 15 minutes and 15 + 30 = 45. Hence, you get 12:45 as your time.
Answer:
-54
Explanation:
First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.
Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.
Now we can substitute -9 for x, so do 6×-9 and you get -54.
Hope this helps :)
Put numbers up and down the X and Y axis showing what the graph values are. (Ex: see picture ) make sure you do it accurately based on what the slope will look like.
