Answer: (3, 6)
Step-by-step explanation:
3x + y = 15
y = 2x
Using substitution:
3x + 2x = 15
5x = 15
x = 15/5
x = 3
y = 2x
y = 2 * 3
y = 6
x = 3
y = 6
= (3, 6)
Yes. 5 meters = 500 centimeters.
The correct choice is w-23=84.
Letting w be the number of wolves on January 1, we know that there are 23 fewer the next year which is given by w-23. We also know that this is a total of 84, so w-23=84.
Use cross multiplication to get x
First you will combine the “x’s” so x+2x=3x then you would add 10 and 6 16 and subtract it to move it to the other side of the = so 2-16= -14 then you would divide 3x and -14 by 3 then there is your answer hope this helps
