the answer for this is:
subtract 7 from 4 to get -3
you then have 2^-3
remove the negative exponent by rewriting as 1/(2^3)
The answer would be "Nine students each make 2 models of Mars and its moons. How many models did they make in total?" Since the answer is 18 and there are 9 students (and also since 18 can be divided into 9), you can divide 18 and 9 to get 2. This makes sense because if each student makes 2 models (as stated), there'd be a total of 18 models (as stated in the question you gave). Hope this helped!
Answer:
x=0
Step-by-step explanation:
Hey there!
<u>Solve </u><u>the </u><u>equation</u><u>:</u>
c = 7 ✅
2c + 3 = 3c - 4
<em>></em><em>></em><em> </em><em>Subtract </em><em>3</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
<em> </em>
2c + 3 - 3 = 3c - 4 - 3
2c = 3c - 7
<em>></em><em>></em><em> </em><em>Substrat </em><em>3</em><em>c</em><em> </em><em>from </em><em>both </em><em>sides </em><em>:</em>
2c - 3c = 3c - 7 - 3c
-c = -7
<em>></em><em>></em><em> </em><em>Divide</em><em> </em><em>each </em><em>side </em><em>by </em><em>-</em><em>1</em><em> </em><em>:</em>
-c / -1 = -7 / -1
c = 7
2c + 3 ⇔ 2(7) + 3 ⇔ 14 + 3 ⇔ 17
3c - 4 ⇔ 3(7) - 4 ⇔ 21 - 4 ⇔ 17
Therefore, your answer is c = 7 .
