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!

The answer is B. 3
It is the only value not attached to a variable, thus remaining constant.
Answer:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Step-by-step explanation:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Divide 230 by 16 and you'll get 14 point a lot of numbers so then just keep adding some cents like $14.20 then multiply by 16 so 16 x $14.20 =227 so then do 16 x $14.40 =230 so your answer is $14.40 I believe
Answer:
y = x + 1
Step-by-step explanation:
I've already explained the process to you, but:
Slope intercept form is y = mx + b
When we count rise over run, we get 1/1, or just 1.
y = x + b (you don't have to write 1x)
The line intersects the y-axis at 1
y = x + 1
