First....6÷1/2= 12
so.....12*3.9=46.8 milligram
If you subtract $43.78 by $27.86 you'd get $15.92 cents left. And if you take that and divide it with $3.98 cents you would get the answer choice C : 4 notebooks
$48.45
Step-by-step explanation:
6.8 ÷ 0.4. = 17
17 × 2.85 = 48.45
I hope this helps you, have a great day!
Answer:
16
Step-by-step explanation:
1st group = 30% or .3 as a decimal
.3 * 40 = 12
2nd group = ate 7
Third group = 1/8 or .125 as a decimal
.125 * 20 = 5
12 + 7 + 5 = 24
40 -24 = 16

Answer: m = 25</h3>
====================================================
Work Shown:
Triangle ABC is congruent to triangle DEF. The order of the lettering is important because it tells us how the angles pair up. We see that angle B and angle E are the second letters of ABC and DEF respectively. Because the triangles are congruent, this leads to angle B = angle E.
Angle B is shown to be 20 degrees, so,
angle E = angle B
2(m-15) = 20
m-15 = 20/2
m-15 = 10
m = 10+15
m = 25
------------------
A slightly alternative way to solve:
2(m-15) = 20
2m-30 = 20
2m = 20+30
2m = 50
m = 50/2
m = 25
------------------
Checking the answer:
2(m-15) = 20
2(25-15) = 20
2(10) = 20
20 = 20
We get the same thing on both sides, so we end up with a true equation. This means the first equation is true when m = 25. The solution has been confirmed.
