Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
Answer:
Step-by-step explanation:
-2 1/3 2 5/9 2.43 2.43
Ok so the base length is 8, the height is 2.72.
So 1/2 * 8 *2.72 should get u the answer.
66.67% decrease. you take the new number and put it over the old number, and then simplify and you have your answer.
