P=7 because when you do bring 63 on the other side it'll be 9p=63 and after that divide both sides by 9 and you'll have p=7
Is this for area and perimeter? If so, first make the fraction a decimal, (that would be 3.5). Then, for permeter, add 3.5 + 3.5 + 9 + 9, which is 25, for area, multiply 3.5 by 9, which is 31.5. Hope this helped!
Yes you are correct. You divide both sides by -6 to isolate x. Dividing both sides by a negative number will flip the inequality sign.
If you need to graph this, then you'll have a closed circle at -12 on the number line. Then you'll have shading to the left of this closed circle. The closed circle indicates "include this endpoint as part of the shaded solution set".
Answer:
-8
Step-by-step explanation:
-1 - y = x
0 - -4 = 4
x / 4 = -2
x = 4 * -2
x = -8
a) 5, 10, -10, -6 (5 and 10 earned from work, 10 and 6 spent on expenses)
b) I'm sorry I can't plot on the computer
c) 3/2, 2/3, 0.5, 5/4; week one and four has the greatest amount eaten because 3/2 and 5/4 are the two largest numbers.
