Answer:

90 coins

Step-by-step explanation:

Nickels = .05

Quarters = .25

half dollars = .50

Since you have an equal number of them, call that x

.05x+.25x+.50x = 24

Combine like terms

.80x = 24

Divide by .8

.80x/.8 = 24/.8

x =30

You have 30 nickes, 30 quarters and 30 half dollars

The total number of coins is

30+30+30 = 90 coins

Answer:

The survey results will be inaccurate since the entire sample of the population was eating at the same restaurant.

Step-by-step explanation:

When doing a survey you must make sure it is unbiased by asking a variety of people for example if you are wondering what is the favorite class at school you have to ask a certain amount of people from each class because if you ask only people from P.E the answer more than likely will be P.E or if u ask 3 people from Art and 17 from P.E your answer will properly be P.E. Make sense?

Answer:

The answer is A) y = -7x - 7.

Step-by-step explanation:

First, you need to subtract '7x' from both sides, and once that is done, the equation is in slope-intercept form because it is in y=mx+b form. I'll attach a photo below that explains my process! :) And another possible answer would be y = 7x + 7, but that is not an option listed above.
