1,000 pennies.
<span>If it was 7/10 full then after she removed 200 pennies it was 5/10 full. (5/10 = 1/2) </span>
<span>Therefore 2/10 is equal to 200 pennies. (7/10 - 5/10 = 2/10) </span>
<span>If 2/10 is 200 then 10/10 is 1000 pennies.</span>

Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=
base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
I'm not sure if you use "x" as your variable, so:
# + 5 = 3 or x + 5 = 3
