7. Jerry has 23 coins in nickels, n, and dimes, d. He
has $1.95 altogether. How many nickels does Jerry
have?

Answers

Answer 1

Answer:

17 nickles !

Step-by-step explanation:

First, identify the variables:

n = amount of nickels

d = amount of dimes

Next, setup the equations based on what you know.  The first equation is:

n + d = 28

For the second equation, we know that a dime is worth 10¢ and a nickel is 5¢, so it should be:

0.05n + 0.10d = 1.95

This a three-step answer:

In one formula (you can use any of them; most people use the simplest one), single out the variable on one side

Apply the first formula into the second formula, and solve it to get the value of one variable

Apply the answer from the second formula into the first formula, and solve it to get the value of the other variable

======

Step One:

n + d = 28

n + d - d = 28 - d

n = 28 - d

Step Two:

0.05n + 0.10d = 1.95

(0.05 * (28 - d)) + 0.10d = 1.95

1.40 - 0.05d + 0.10d = 1.95

1.40 + 0.05d = 1.95

1.40 - 1.40 + 0.05d = 1.95 - 1.40

0.05d = 0.55

d = 11

Step Three:

n = 28 - d

n = 28 - 11

n = 17

======

Your answer should be 17 nickels and 11 dimes.

You can double check by applying the variables into both formulas.

n + d = 28

17 + 11 = 28

28 = 28

0.05n + 0.10d = 1.95

(0.05 * 17) + (0.10 * 11) = 1.95

0.85 + 1.10 = 1.95

1.95 = 1.95

I hope this helped.

Answers

Answer:

Adjacent

x = 14

Step-by-step explanation:

Find the diagram attached

Adjacent angles places side by side and can also be on the same straight line. Since 5x and x+96 are on the same straight line ans placed side by side, then the angles are adjacent.

The sum of angle on a straight line is 180 degrees, hence;

5x + x+ 96 = 180

6x = 180 - 96

6x = 84

x = 84/6

Write and evaluate two equivalent numerical expressions that show Distributive Property of Multiplication

Answers

Answer:

2(x+5) = 2x+10

Step-by-step explanation:

I'm assuming you can use any possible combination of two equivalent numerical expressions for your question.

2(x+5) = 2x+10

2 times x is 2x. 2 times 5 is 10. So, you get 2x+10

The distributive property of multiplication involves taking the product a certain value and another variable joined by either an addition or subtraction operator.

3(x + 5) = 3x + 15

For instance :

a(b + c) = a×b + a×c = ab + ac

The expressions below shows distributive property of multiplication :

3(x + 5) and 3x + 15 exhibits the distributive property of multiplication.

3(x + 5)

Opening the bracket :

3×x + 3×5 = 3x + 15

Hence,

3(x + 5) = 3x + 15

Use the slope and y-intercept to write an equation for the red cab.

Answers

Answer:

y = 1/4x + 6

Step-by-step explanation:

For the red cab:

Points on the graph: (0, 6) and (8, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-6)/(8-0)

m=2/8

m= 1/4

Slope-intercept:

y - y1 = m(x - x1)

y - 6 = 1/4(x - 0)

y - 6 = 1/4x

y = 1/4x + 6

Answer:

y = [tex]\frac{1}{4} x[/tex] + 6

Step-by-step explanation:

The slope can be determined by taking any two random pair of points on the red line.

For example, (0,6) and (4,7)

m = y2-y1 / x2-x1 = 1/4

Your y intercept is where your line intersects on the y axis. Here, it is at y = 6.

Now, you have the slope and y intercept to write the equation of the red cab.

y = [tex]\frac{1}{4} x[/tex] + 6

Answers

Line 1

x - 5y = 15

x - 15 = 5y

Therefore slope = 1/5

Line 2

Point = (-5,7)

Slope = 1/5

Therefore: 7 = (1*-5)/5 + c

=> 7 = -1 + c

=> c = 8

Therefore equation: y = x/5 + 8
