Answer:
There were 186 math textbooks sold and 62 physics textbooks sold.
Given:
- 248 books sold in total
- math textbooks and physics textbooks sold
- math is three times physics
Step-by-step explanation:
[] First, we can set up mathematical equations for this scenario;
- Let <em>m</em> be math textbooks and <em>p</em> be physics textbooks
<em>m</em> = 3<em>p</em>
248 = <em>p</em> + (3<em>p</em>)
248 = 4<em>p</em>
62 = <em>p</em>
[] Now we can solve for the amount of each books sold;
<em>p</em> = 62 books
3 * <em>p</em> = <em>m</em>
3 * 62 = <em>m</em>
<em>m</em> = 186
[] Lastly, we can check to make sure this will work;
186 + 62 = 248 ✓
Have a nice day!

D.
9
Step-by-step explanation:
Yes, she eventually stops talking; either due to hoarseness, fatigue or death.
the exponent tells you how many times to multiply the base number by itself.
for 35 the base number or base is 3 and the exponent is 5
the value is 3 x 3 x 3 x 3 x 3 which has 3 multiplied by itself five times
So your question is going in the opposite direction.
Rather than going from a power and expanding it, we have the expanded form and we are asked to write the power
3 x 3 x 3 is written 33
2/5x + 1.5y = 7x - 2y
1.5 y + 2y = 7 x - 2/5x
You can this
1.5 y + 2y = 7x - 0.4x
3.5y = 6.6x
