Answer:

Step-by-step explanation:

Let's disect the problem. Three times a particular number plus fourteen equals 20. Let's make an equation, and replace the number with x.

<h2>3x + 14 = 20</h2><h3>The "3x" represents the 3 times the number,</h3><h3>the 14 represents the 14 added to make 20.</h3><h2>Let's solve the equation!</h2>

We'll first minus 14 from each side to balance the equation, but with the intention of isolating the variable, x.

We have almost successfully isolated the variable. To isolate the variable, we can divide by three on each side.

<h2>x = 2</h2><h2>The number is 2.</h2>

Answer:

$11$ bushels of apples were sold

Step-by-step explanation:

Let

x----> bushels of peaches

y----> bushels of apples

we know that

$7x+6y=346$ -----> equation A

$x=y+29$ -----> equation B

substitute equation B in equation A and solve for y

$7(y+29)+6y=346$

$7y+203+6y=346$

$13y=346-203$

$13y=143$

$y=143/13=11$

Answer:

{5, 10, 15, 20}

Step-by-step explanation:

Multiples of 5 are of the form 5n, where n is an integer. The ones of interest will satisfy ...

0 < 5n < 23

0 < n < 4.6

That is, the multiples of 5 we want are for values of n that are 1 through 4. The set is ...

5 × {1, 2, 3, 4} = {5, 10, 15, 20}

Solve for 6y+12=3y-3

kherson [118]

6y + 12 = 3y - 3

Subtract 3y on both sides

3y + 12 = -3

Subtract 12 on both sides

3y = -15

Divide by 3 on both sides

y = -5
