Answer:
9
Step-by-step explanation:
there is likely a number missing in what you said the width was equal, so you may need to plug in a number in the work I provide, if so.
A=x-16
W=x+1 (assuming it just wants any number to be able to be added to the 1)
We first need to use the area formula to setup the problem
A=W*L
area equals width times length
We can divide both sides by W to solve for L and get
A/W=L
from here we can just plug in the given values for area and the width
(x-16)/(x+1)=L
This should answer your question, but the x in the denominator may need replaced if the * in your given width is actually a different value besides x.
Answer:
(b) 3x -5
Step-by-step explanation:
You can slog through the entire long division process, or you can realize that the product of the quotient constant and the divisor constant must match the dividend constant. If we let q represent the quotient constant, you must have ...
4q = -20
q = -20/4 = -5
The only answer choice with a constant of -5 is choice B, 3x -5.
Answer:
Option C and D
Step-by-step explanation:
The teacher wants to evaluate how many students will attends the comedy class and how many will attend the musical performance. Hence, He must be able to determine the number of students attending the drama club and theatre club as this will help him in determining the approximately correct number of students attending comedy or music class.
Hence, option C and D are correct
Step-by-step explanation:
2nd number = x
1st number = x - 7
5 (x - 7) = 6x + 9
5x - 35 = 6x + 9
- x = 44
x = - 44
1st number = -51
2nd number = -44
Proof: 5 (-51) = 6(-44) + 9
-255 = -264 + 9
-255 = -255

Also, I think that Brainly is an awesome app, but there's an app which is doing great work for me in maths, named Gauthmath. I will suggest it. Video concepts and answers from real tutors.
