At the beginning of the season, MacDonald had to remove 5 orange trees from his farm. Each of the remaining trees produced 210 o

Korolek [52]

Let t = initial number of trees "remove 5 trees at the start of the season" means (t - 5) remain "each remaining tree made 210 oranges for a total of 41,790 oranges" means ( t - 5) * 210 = 41790 Now, you can solve for t: (t-5)(210) = 41790 [just re-writing] 210t - 1050 = 41790 [distribute] 210t = 42840 [add 1050 to each side] t = 204 [divide each side by 210] There were initially 204 trees. After 5 were removed, the remaining 199 produced 210 oranges each for a total of 199*210 = 41790 oranges.

The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to e

shutvik [7]

Given:

The system of equations is

$x+3y=42$ ...(i)

$2x-y=14$ ...(ii)

To find:

The number that must be multiplied with the second equation to eliminate the y-variable.

Solution:

Coefficient of y variable in equation (i) is 3 and in equation (ii) is -1.

To eliminate y-variable the absolute value of coefficients of y-variables should be same.

So, we need to multiply the second equation by 3 to eliminate the y-variable

Multiplying equation (ii) by 3, we get

$6x-3y=42$ ...(iii)

Adding (i) and (iii), we get

$x+3y+6x-3y=42+42$

$7x=84$

Divide both sides by 7.

$x=12$

Put x=12 in (i).

$12+3y=42$

$3y=42-12$

$3y=30$

Divide both sides by 10.

$y=10$

Therefore, x=12 and y=10.

you are a school photographer taking individual and class pictures for 2 classes of 21 students each on average each individual

uysha [10]

Answer: Approximately 146 minutes (or if you need the simplified version the answer is 2 hours and 26 minutes). Step-by-step explanation: Step 1. Two classes of 21 students. To calculate that you would multiply 21 by 2. 21*2=42 Step 2. So now we know you need 42 individual pictures. If they each take 3 minutes to take you need to multiply 42 by 3. 42*3=126. So now you know it’ll take 126 minutes to take all the individual pictures. Step 3. Now, there are 2 classes of people and it takes 10 minutes to take each class picture. So do calculate that you need to multiply 10 by 2. 10*2=20. So it’ll take 20 minutes to take both class pictures. Step 4. Now we know it’ll take 126 minutes to take all the individual photos and 20 minutes to take the class photos. Now to calculate the total amount of time it’ll take to take all the photos you need to add 20 to 126. 126+20=146. So, it’ll take 146 minutes to take all the photos. Step 5. (You can skip this step if no simplification is needed in your problem) So, we all know there is 60 minutes in an hour so we’ll divide 146 by 60. 146/60=2.43. So, now we know it’ll take 2.43 hours to take all the photos. 2.43 hours is 2 hours and 26 minutes. I hope this helps!
