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.

Answers

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.

Step-by-step explanation:

12) y = 4 + 7x

x = 3,-1

y = 4 + 7(3) = 25

13) y = x - 11

x = 72,

y = 72 - 11 = 61

14) y = 6x - 5

y = 6(-4) - 5 = -29

y = -11 (x = -1)

y = -5 (x = 0)

y = 13 (x = 3)

15) y = x + 1, each relation is a function

16) An = 22 + (n-1)11

A(2) = 22 + 1(11) = 33

9x+7y=7 find the slope

Answers

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.

The answer is -9/7 I hope this helps

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

Answers

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.
