Jude has 30 coins of quarters and nickels. The total amount he has is $5.10. How many of each coin does Jude have? Write the system. Write the equations in the order that they appear in the problem.
Answer: Required system
x+y= 30
0.25x+0.05y=5.10
Jude has 18 quarters and 12 nickels.
Step-by-step explanation:
Let x= Number of quarters
y= Number of nickels
As per given,
x+y= 30 (i)
0.25x+0.05y=5.10 (ii) [1 quarter = $0.25 , 1 nickel = $0.05]
Multiply 0.25 on both sides of equation (i)
0.25x+0.25y= 7.5 (iii)
Eliminate (ii) from (iii) , we get
0.20y=2.4
⇒ y = 12 [divide both sides by 0.20]
Put value of y in (i\), we get
x+12=30
⇒ x= 30-12= 18
Hence, Jude has 18 quarters and 12 nickels.

Answer:
x = 12, y = 128
Step-by-step explanation:
9 * 12 + 19 = 127
5 * 12 - 7 = 53
127 + 53 = 180
180 - 53 + 1 = 128
y = 128
Answer:
x = 12
y = 128
Step-by-step explanation:
straight lines equal 180 degrees. so then you would just set them equal to 180

9x+7y=7 find the slope
Answer:
-9/7
Step-by-step explanation:
Put the equation into y = mx + b form, by first isolating y:
9x + 7y= 7
7y = -9x + 7
Divide each side by 7:
y = -9/7x + 1
So, -9/7 is the slope.
A game show contestant starts a game by answering three
questions incorrectly. Each incorrect answer costs the
contestant $900. What integer would represent the point total
for the contestant?
(Pls help)
Answer:
The negative integer would show for subtraction of money but when the person earns money the money will show in positive integer
The integer -3 will represent the total points for the contestant.
What are the different interpretation of negative numbers?A negative number is a number that is less than zero.Numbers that are to the left of zero on the number line.A number that is the opposite of a positive number. A negative number represents loss or absence of something.According to the given question.
Let +1 point will be awarded to the contestant for giving the correct answer. And -1 point for giving the incorrect answer.
Number of questions for which the contestant given the answer
incorrectly = 3
Amount of money have to pay by contestant for each incorrect answer
= $900
Therefore, the amount have to pay the contestant for three incorrect questions = -3 × $900 = -$2700
Where, a negative number shows the amount contestant has to pay or loss of the contestant.
Hence, the integer which represent the total point for the contestant is -3.

An employee is walking home from work and wants to take the long way to get more exercise. The diagram represents the two
different routes, where A is the employee's work and B is the employee's home. Which route is longer and by how much? will mark brainliest
Answer:
The route from A to the corner to B is longer then going directly from A to B. It is roughly 1.6 miles longer.
Step-by-step explanation:
The distance from A to the corner to B is 5.9 miles because
[tex]3.8 + 2.1 = 5.9[/tex]
Going directly from A to B is roughly 4.3 miles because of
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex]5.9 - 4.3 = 1.6[/tex]
Answer:
Walking to the right and downwards to reach B from A.
Approximately [tex]1.6[/tex] miles.
Step-by-step explanation:
Route 1 - Walking to the right and downwards to reach B from A:
The distance is [tex]2.1+3.8=5.9[/tex] miles
Route 2 - Walking straight to B from A:
[tex]\sqrt{3.8^2+2.1^2} = \sqrt{14.44+4.41}[/tex] (using the Pythagorean theorem, the two lengths are perpendicular)
[tex]=\sqrt{18.85}[/tex]
[tex]=4.341658669[/tex] miles (approximately from calculator)
Since [tex]5.9[/tex] miles is greater than [tex]4.341658669[/tex] miles, therefore walking to the right and downwards to reach home from work is the longest distance.
Difference in distance:
[tex]5.9-4.341658669=1.558341331[/tex] miles
Route 1 is longer than route 2 by [tex]1.558341331[/tex] miles, or approximately [tex]1.6[/tex] miles.
