Answer:
He made seven A's.
Step-by-step explanation:
360-220=140
140/20=7
H = 3.
FIRST STEP:
<span>Add 1 to both sides to get rid of the -1 on the left side.
4h-1 = 3h+2
</span><span>4h-1 (+1) = 3h+2 (+1)
</span><span>4h = 3h+3
SECOND (FINAL) STEP:
Subtract 3h from both sides to get rid of the 3h on the right side.
</span>4h(-3h) = 3h+3 (-3h)
h = 3
Hope this helps, sorry if it's hard to understand :)

Answer:
30 J
Step-by-step explanation:
Given : -
Height ( h ) = 3m
Weight ( W ) = 10 N
To find : GPE = ?
Note : -
GPE is Gravitational Potential Energy.
It is expressed in Joules ( J ).
Formula : -
W = mg
mg = 10 N
Formula : -
GPE = mgh
GPE = 10 x 3
GPE = 30 J
Therefore,
A bird weighs 10 N and is standing 3 m, it's
GPE is 30 J.
1 meter = 100 cm
To convert meters to cm multiply the given meters ( 0.03) by 100.
0.03 x 100 = 3
The answer would be 3
