Answer:
x = -3, y = 9
Step-by-step explanation:
-5x - 5y = -30
x - y = 6
x = -y + 6
10x + 3y = -3
10(-y + 6) + 3y = -3 (plug in x from the previous equation)
60 - 10y + 3y = -3
60 - 7y = -3
-7y = -63
<em>y = 9</em>
x = -y + 6
x = -(9) + 6
<em>x = -3</em>
Answer:
1120
Step-by-step explanation:
Hey there!
Let's find their areas first. Rectangle area is defined as length times width, so we have:
A- 10 * 4 = 40 units squared
B- 4 * 2 = 8 units squared
Let's try all of our answers:
A) If A had twice the area, it's area would be 8. No
B) This is true, as 40 is 8 times 5, so rectangle A has 5 times as much area.
Your answer is B.
Hope this helps!
