To use algebraic methods to solve geometric problems.
Put the value of x = -2 to the equation of the function y = -4x + 3:
y = -4(-2) + 3 = 8 + 3 = 11
<h3>Answer: A. (-2, 11)</h3>
Here, we need to set up a proportion.
4.5 miles in 15 minutes.
In 75 minutes, how much miles can he ride?
4.5/15 = x/75
Cross multiply
4.5 * 75 = 337.5
15*x = 15x
15x = 337.5
15x/15 = 337.5/15
x= 22.5
Final answer:- Tommy can ride 22.5 miles in 75 minutes.
Based on the information given, it should be noted that the least number of marbles that can be in the bag will be 10 marbles.
<h2>
Solution to the probability.</h2>
If the bag contains 60 marbles, the number of red marbles will be:
= 1/5 × 60
= 12 marbles.
The number of white marbles will be:
= 3/10 × 60
= 18 marbles.
The number of blue marbles will be:
= 60 - (12 + 18)
= 60 - 30
= 30 marbles.
Furthermore, when the bag has 4 red marbles and 6 white marbles, there'll be 10 blue marbles.
Lastly, to find the probability of choosing a blue marble, we've to multiply 1/2 by the number given.
