Answer:
there will be 300 6th graders
Step-by-step explanation:
Divide 200 by 2 to find 1/5 of the school.
D = 14
1/6d + 2/3 = 1/4d - 1/2
2d + 4*2 = 3d - 6
2d - 3d = -6-8
-d = -14
d = 14
It should be
3cm
1.3cm
7in
the pythagorean theorem is that the two smaller sides is equivalent to the biggest side. (A+B = C)
$2.99/20 will be the unit price of soup. Then the amount Riley has to pay for 12 ounce would be 12*2.99/20=$1.794
