Solve x
Substitute -y+6 for x in 3x-4y=-31
3x-4y=-31
3(-y+6)-4y=-31
Simplify both sides of the equation
-7y + 18 = -31
Add -18 to both sides
-7y+18-18=-31-18
7y= -49
Divide both sides by -7
7y/-7= -49/-7
y= 7
Substitute 7 for y in x = -y+6
x= -y+6
x= -7+6
Simplify both sides of the equation
x= -1
Answer : x= -1 and y = 7
I hope that's help and have a great night !
Answer:
Step-by-step explanation:
Jacob is dividing 6 aquariums into 1/8 of an aquarium sections for his different animals. How many 1/8's are there in Jacobs aquariums?
To get the number of 1/8 in Jacobs aquariums,we simply divide 6 by 1/8
6 ÷ 1/8
But whenever you are dividing by a fraction, you can simply change the division to multiplication in order to make your work easier, all you need to do to change the division to multiplication is to simply turn the number over, that is; the denominator becomes the numerator and the numerator becomes the denominator,
In this case 8 becomes the numerator and 1 becomes the denominator
Hence;
6 × 8 /1 = 6 × 8 = 48
Therefore, the number of 1/8's in Jacobs aquariums are 48

Answer:
Option C.
Step-by-step explanation:
A perpendicular line to 2/3 will be the reciprocal and negative of this fraction. Therefore:
Slope of perpendicular line = -3/2.
Remember, the equation for solving for the slope is:
We must find points that when plugged into this equation, equal to -3/2.
Plugging in the points in option A:
Option B:
Option C: This is the correct answer.
Option D:
