What’s the proportion

Answers

Answer 1

Answer:

10/k=8/4

10*4=8k

K=40/8

K=5

Answer 2

Hey there!

“10 / k = 8 / 4”

FIRST: CROSS MULTIPLY

10(8) = 4(k)

10(8) = 80

4(k) = 4k

NEW EQUATION: 80 = 4k

SECOND: FLIP/TURN the EQUATION

4k = 80

THIRD: DIVIDE both SIDES by 4

4k / 4 = 80 / 4

CANCEL: 4 / 4 because that gives you 1

KEEP: 80 / 4 because that gives you the value of k

NEW EQUATION: 80 / 4 = v ; v = 80 / 4

FOURTH: SOLVE above and you have the k-value

Answer:

k = 5☑️

Good luck on your assignment and enjoy your day!

System of equations
There are
nickels in your pocket and
dimes in your pocket

Answers

Answer:

6 nickels and 4 dimes

Step-by-step explanation:

6 times .05 is .30

4 times .10 is .40

just add them

.40 + .30 = .70

The equation should be:

.70 = .10y + .05x

I have 4 dimes and 6 nickels.

The question is ill-formatted. The following is the question.

You have a total of ten coins in your pocket, all of which are nickels and dimes. The total value of the coins is $0.70. To find nickels and dimes in your pocket, write and solve a system of linear equations. Let x represents the number of nickels and let y represent the number of dimes. Find the number of nickels and dimes.

How much is a cent?

One-hundredth of a dollar is equivalent to one cent.

How much is a nickel?

A nickel is worth 5 cents. That means $0.05.

How much is a dime?

A dime is worth 10 cents. That means $0.10.

How to solve the question?

As per the question,

conversion of the statements into mathematical equations:

"You have a total of ten coins in your possession, all of which are nickels and dimes."
this statement is converted into
x+y=10"The coins have a total value of $0.70."
this statement is converted into
0.05x+0.10y=0.70
⇒x+2y=14

Subtracting the above equation from the below equation we get y=4.
And by substituting y=4 in x+y=10 we get x=6.

Hence, I have 4 dimes and 6 nickels.

C. Discount: $13.56; Sale Price: $4.39

D. Discount: $7.18; Sale Price: $10.77

Answers

Answer:

Step-by-step explanation:

multiply $17.95 by 40% to get the discount ($17.95 x .4), which equals $7.18.

the sale price is the initial price of the book less the discount ($17.95-$7.18), which equals $10.77.

Answer:

Step-by-step explanation:

-2x +4 < 12

-2x < 12 -4

-2x < 8

x > -8/2

x > -4

Answer:

x > - 4

Step-by-step explanation:

- 2x + 4 < 12 ( subtract 4 from both sides )

- 2x < 8

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x > - 4

A family has three children.The oldest is 4 years older than the middle,and the youngest child is 2 years younger than the middle child.The sum of the ages of the children is 26.

Answers

Answer:

The age of the youngest child = x = 6 years

The age of middle child = y = 8 years

The age of the oldest child = z = 12 years

Step-by-step explanation:

Let us represent:

The age of the youngest child = x

The age of middle child = y

The age of the oldest child = z

The sum of the ages of the children is 26.

Hence: x + y + z = 26...... Equation 1

The oldest is 4 years older than the middle

z = 4 + y

The youngest child is 2 years younger than the middle child

x = y - 2

Hence, we substitute 4 + y for z and y - 2 for x in Equation 1

x + y + z = 26...... Equation 1

y - 2 + y + 4 + y = 26

y + y + y -2 +4 = 26

3y + 2 = 26

Subtract 2 from both sides

3y + 2 - 2 = 26 - 2

3y = 26 - 2

3y = 24

y = 24/3

y = 8

Solving for x

x = y - 2

x = 8 - 2

x = 6

Solving for z

z = 4 + y

z = 4 + 8

z = 12

Therefore:

The age of the youngest child = x = 6 years

The age of middle child = y = 8 years

The age of the oldest child = z = 12 years
