Answer: y=15

Step-by-step explanation:

Solution for (5y+3)+(4y+8)=146 equation:

Simplifying

(5y + 3) + (4y + 8) = 146

Reorder the terms:

(3 + 5y) + (4y + 8) = 146

Remove parenthesis around (3 + 5y)

3 + 5y + (4y + 8) = 146

Reorder the terms:

3 + 5y + (8 + 4y) = 146

Remove parenthesis around (8 + 4y)

3 + 5y + 8 + 4y = 146

Reorder the terms:

3 + 8 + 5y + 4y = 146

Combine like terms: 3 + 8 = 11

11 + 5y + 4y = 146

Combine like terms: 5y + 4y = 9y

11 + 9y = 146

Solving

11 + 9y = 146

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-11' to each side of the equation.

11 + -11 + 9y = 146 + -11

Combine like terms: 11 + -11 = 0

0 + 9y = 146 + -11

9y = 146 + -11

Combine like terms: 146 + -11 = 135

9y = 135

Divide each side by '9'.

y = 15

Answer:

$12.55 per CD

Step-by-step explanation:

If each CD is of equal price, you must then divide the price by the number of CD's. (75.30/6=12.55)

Answer:

$75.30/6 = $12.55 per CD

Step-by-step explanation:

Since the CDs are equally-priced, my thought is that you would divided the quantity that you purchased by your total to get your answer. So, your total, $75.30 divided by, the amount of CDs purchased, 6. This would lead you to the answer $12.55, which is the cost of each CD. To check your answer you would multiply $12.55 by 6 to get $75.30.

Answer:

Okay so if your current scores are 93, 97, 89 and 81, You would have to score at least a 90. Even if you scored a 100%, the highest you would be able to make is a 92 average.

Step-by-step explanation:

Here's the thing about average, all you do is take all of the numbers, add them up, then divide them by the number of numbers there are.

For example, 93 + 97 + 89 + 81 = 360. There are 4 numbers so you would take 360 and divide it by 4 which gets you 90. 90 is your average.

To figure out the highest score you are able to get, take the highest score you can possibly score (100) and add it to the mix. 93 + 97 + 89 + 81 + 100 = 460. Now, there are 5 numbers. So you take 460 and divide it by 5 which will get you 92.

Answer:

Step-by-step explanation:

1.  Equation representing when both companies will cost the same amount :

[tex]350 + 15x = 275 + 20x[/tex]

2. Let x equal the number of hours a job takes , then the first house painting company will charge 350+15x , the second house painting will charge 275 +20x. If the two companies charge the same amount , we will have;  

[tex]350 +15x = 275+20x\\\\350 - 275 = 20x - 15x\\\\75 = 5x\\\\\frac{75}{5} = \frac{5x}{5} \\\\15 = x\\\\x = 15\:hours[/tex]

3. For a job that takes 15 hours , the first company will cost ;

[tex]350 + 15(15) = 575[/tex]

For a job that takes 15 hours , the second company will cost ;

[tex]275+20x\\\\275+20(15)\\\\275 +300\\\\=575[/tex]

Answer: x = 30

Step-by-step explanation:

Since AB and CD are straight lines, vertical angles formed by them are congruent. Angle DOB is equal to angle AOC which is equal to 2x. Since you know that a straight angle is equal to 180 degrees, you can say :

2x + 90 + x = 180

3x + 90 = 180

3x = 90

x=30

Answer:

73

Step-by-step explanation:

Answer:73

Step-by-step explanation:

Answer/Step-by-step explanation:

1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°

2. m<ECF = m<BCD (corresponding angles)

m<ECF = 38° (substitution)

3. m<DCF + m<ECF = 180° (linear pair)

m<DCF + 38° = 180° (substitution)

m<DCF = 180° - 38° (Subtraction property of equality)

m<DCF = 142°

The measure of the following angles are as follows;

∠BCD = 38°

∠ECF = 38°

∠DCF = 142°

When a transversal line cut across parallel lines, the angles form include corresponding angles, alternate angles etc.

Therefore,

∠BCD = 38 degrees(alternate angles)

∠ECF = 38 degrees(corresponding angles)

∠DCF = 180 - 38 = 142 degrees(angles on a straight line)

Answer:

11 minutes and 15 seconds (11.25 minutes/ 11 and 1/4)

Step-by-step explanation:

create the corresponding ratio by dividing 200 by 15, 200 calories per 15 minutes. Which equates to 40 calories every three minutes which means 40/3 or 13 1/3 calories every minute. You can verify this by multiplying 15 and 40/3 to get 200 again.

The last step is to divide the calories burned by the corresponding ratio (40/3)

150/(40/3) = 11.25

and .25 or 1/4 of 60 seconds(in a minute) is 15 since 60/4 = 15.

Answer:

x=16

Step-by-step explanation:
