First one, third one and the last one. Hope this helps
2/5 + p = 4/5 + 3/5 pSimplifyp + 2/5 = 3/5 p + 4/5Subtract 3/5p from both sidesp + 2/5 -3/5p = 3/5p + 4/5 -3/5 p2/5 p + 2/5 =4/5Subtract 2/5 from both sides2/5 p +2/5 -2/5 = 4/5 -2/52/5 p = 2/5Divide both sides by 2/52/5 p / 2/5 = 2/5 /2/5p = 1
7x-2(x+1)=6x+14
7x-2x-2=6x+14
5x-6x=14+2
-x=16
x=-16
Sphere surface area is A=4pi*r^2. So r is sqrt(A/4pi)
r=4cm. So d=8cm
The inequality represents x, the number of microwave burritos, and y,
the number of peanut butter sandwiches, she can eat each week is 490x +
700y < 4000. I hope the answer will help.
