20x-7= 5+16x
Add 7 to both sides
20x= 12+16x
Subtract 16x from both sides
4x=12
Divide both sides by 4
x=3
Final answer: x=3
We have that
<span>log10 E = 4.4 + 1.5<span>M
</span></span>E=<span>the released energy in Joules (J)
M= </span><span>earthquake measures---------- > 3.6
</span>log10 E = 4.4 + 1.5*3.6
log10 E = 9.8----------> E=10^(9.8)= 6.309573444 x10^9 J
<span>
the answer is </span>6.309573444 x10^9 J<span>

Answer:
(7.5, 3)
Step-by-step explanation:
(5,5) and (10, 1)
Midpoint:
28 is 4 times 7, so we will rewrite it like that.
7 is 7 times 7, so we will rewrite it like that.
So the simplest form is,
Answer:
12 and 16
Step-by-step explanation:
The ratio between the groups is 3:4, so the fractions are 3/7 and 4/7.
3/7 (28) = 12
4/7 (28) = 16
Check your answer: 12 + 16 = 28, and 12/16 = 3/4.
