Answer:
x= -2, y = -2
Step-by-step explanation:
Solve the following system:
{2 y - 4 x = 4 | (equation 1)
{4 x - y = -6 | (equation 2)
Add equation 1 to equation 2:
{-(4 x) + 2 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by 2:
{-(2 x) + y = 2 | (equation 1)
{0 x+y = -2 | (equation 2)
Subtract equation 2 from equation 1:
{-(2 x)+0 y = 4 | (equation 1)
{0 x+y = -2 | (equation 2)
Divide equation 1 by -2:
{x+0 y = -2 | (equation 1)
{0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = -2

Answer:
The answer is A
Step-by-step explanation:
That is because one million has 6 digits and I'm guessing that the flea is measured in millimeters. So you just add the two decimal places. So, you add the one million (count the number of zeroes in a million) to the number of decimal places that the dot was moved. So from a measure of meter you move the dot one place right and you decrease the measuring unit. So, first is meter then centimeter and then millimeter.
She gonna need to buy 32 boxes because 315 divided by 10 is 31 r 5 and also you can't buy 31 boxes because 5 kids aren't gonna have pencils so she needs to buy 32 boxes of pencils
X=3
okay so Angles YXZ and YZX are congruent.
180 = 136 + 2(10x-8).
180-136 = 2(10x-8).
44 = 2(10x-8).
44/2 = 10x-8.
22=10x-8.
22+8 = 10x.
30 = 10x.
3 = x.
