Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 3y − 11
The perimeter of a square is a^2. In this case a= (4x-2y) so a^2=(4x-2y)^2 , a^2={16(x)^2-16xy+4(y)^2}
Answer:
-75, -73, -71
Step-by-step explanation:
<u>Let the numbers be:</u>
<u>The sum:</u>
- x + 2 +x + x+2 = -219
- 3x = -219
- x = -73
<u>The numbers:</u>
Answer:
Half a mile
Step-by-step explanation:
A mile is 1600 meters so half a mile is 800 meters
Answer:
6:9
Step-by-step explanation:
Lets assume the relationship between the amount of blue and red marbles are proportional. If there are 6 red marbles , then we would need need to find out how much times you multiplied 2 by to get.
6/2 is 3, which means that you multiplied the red marbles by 3 to get 6 of them.
Since the relationship between red and blue marbles is equivalent, we just need to multiply the blue marbles by 3 as well, to even it out.
3x3=9
There are 9 blue marbles if there are 6 red marbles.
