The equation to your question would be P =10(c)+20. meaning 10 pencils in each box multiplied by the number of boxes (c) plus the 20 pencils the teacher gives her will equal the number of pencils (P) she has altogether. (C stands for the number of boxes and P stands for pencils)
so lets say she has 3 boxes. well, c stands for boxes soooo...... all you have to do is plug in 3 were c is. giving you this equation P = 10(3)+20. then all you have to do is solve. P = 10(3)+20
10 times 3 = 30 so P = 30+20
then add 30 and 20 P = 50 she has 50 pencils altogether
(remember this is just an example, 50 pencils is NOT the answer to your question. but you can use the equation i gave you to find your own answer!) :) Hope this helps!!
Answer:
52
Step-by-step explanation:
each inch cost 4 cents
X - 7 < 3
Add 7 to both sides
Final Answer: x < 10
Answer:
B is correct
Step-by-step explanation:
A, C, and D all depend on the first event in some way, but B is the only one that does not depend on the first event in any way.
A) Parallel lines have the same slope. 5 and 1/5 are not equal, so they are not parallel.
b) Perpendicular lines have negative reciprocal slopes. That means when you multiply the slopes together, you get -1. Let's try our slopes. 5 * 1/5 = 1, not -1, so these slopes are not negative reciprocals, and the lines are not perpendicular.
c) A vertical line has undefined slope since the slope of a vertical line involves division by zero. Here, the two lines have well defined slopes. The lines are not vertical.
d) This is the only choice left, so it is the answer.
