Ivan only, because an odd number of negatives does not always make negatives while an even number does.
Answer:
D:) (2,2,) is the Answer
Step-by-step explanation:
Solve the following system:
{X - 2 Y = -2 | (equation 1)
{3 X - 2 Y = 2 | (equation 2)
Swap equation 1 with equation 2:
{3 X - 2 Y = 2 | (equation 1)
{X - 2 Y = -2 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 X - 2 Y = 2 | (equation 1)
{0 X - (4 Y)/3 = (-8)/3 | (equation 2)
Multiply equation 2 by -3/4:
{3 X - 2 Y = 2 | (equation 1)
{0 X+Y = 2 | (equation 2)
Add 2 × (equation 2) to equation 1:
{3 X+0 Y = 6 | (equation 1)
{0 X+Y = 2 | (equation 2)
Divide equation 1 by 3:
{X+0 Y = 2 | (equation 1)
{0 X+Y = 2 | (equation 2)
Collect results:
Answer: {X = 2 , Y = 2
You could say 8r+2 times s +4 or –5x2y4
Answer:
10 quarts = 20 pints.
Step-by-step explanation:
Hope my answer has helped you and if not I am sorry.
Simplify 7/20 to decimals by dividing.
7 divided by 20= 0.35
Rose bought 0.35 kilograms of candy and 0.4 kilograms of fruit.
So, she bought more fruit, since 7/20 is less than 0.4.
I hope this helps :)
