The coefficients of x are different in the expressions, but the constant values are the same. Zero times any value is zero, so both expressions will be equal to -5.9. If Ryan tried any other number, he would see that the expressions are not equivalent.

if my answer helps please mark as brainliest.
Answer:
B
Step-by-step explanation:
Number of rooms to be cleaned in 6 days = 72
Number of rooms to be cleaned in 1 day = 72 ÷ 6 = 12
Number of rooms to be cleaned in 9 days = 12 * 9 = 108 days
You plan on purchasing a car in the next year. The car that you are interested in lists for $23,000 after taxes, license, and doc fees. You currently have two-thirds of the vehicles value saved and you get paid $1,312.00 twice a month. Given that monthly expenses total $1,150.12, Social Security is 6.2% of your income, Medicare is 1.45% of your income, and you pay State and Federal taxes in the amount of $53.00 and $101.35, respectively, twice a month, determine in how many months you will have to save for so that you can purchase the car without financing. Round all your answers to the nearest cent. Round your answer to the nearest month.
a.
7 months
c.
8 months
b.
6 months
d.
9 months
Answers
Answer:
c. 8 months.
Step-by-step explanation:
First let's break down all the expenses and taxes to come up with how much we save each month and subtract it to our total salary monthly.
Total Salary : $1312.00 x 2 = $2,624.00
Current Savings : 2/3 or 0.67 = $15333.33
| Expenses |
Monthly Expenses : $1,150.12
Social Security : 6.2% or 0.062 x 2,624 = $162.69
Medicare : 1.45 or 0.0145 x 2,624 = $38.05
Taxes: $53 + $101.35 = 154.35 x 2 = $308.7
So we sum up all the expenses.
= $1659.56 Total Expenses.
Now we have to find how much extra money we have each month.
= $964.44 Extra Money
Now we subtract our current savings to the total price of the car.
= -7666.67 Balance
Now we divide the total balance to our extra money monthly.
= 7.949 Months or 8 Months
A construction worker dropped a hammer while building the Grand Canyon skywalk, 4000 feet above the Colorado River. Use the formula, t = h 4 , to find how many seconds it took for the hammer to reach the river. Round your answer to the nearest second.
Answers
Answer: Hammer reaches river after 15.8 seconds.
Step-by-step explanation:
Use formula: t = square root of h divided by 4. In this problem h = 4,000.
Therefore,
T = square root of 4,000 divided by 4.
T = 15.8 seconds
Kamal is buying supplies for a science lab. He needs a piece

A 19 in.
B

74 in.
84 in.
Answers
Answer:
kamal needs to buy 84 in of wire.
Step-by-step explanation:
multiply the length value by 12:
if he wants 7 feet, and the store only sells it in inches, then we know what a foot is twelve inches so 12x7=84.

The Wellbuilt Company produces two types of wood chippers, economy and deluxe. The deluxe model requires 3 hours to assemble and 1/2 hour to paint, and the economy model requires 2 hours to assemble and 1 hour to paint. The maximum number of assembly hours available is 30 per day, and the maximum number of painting hours available is 9 per day. (a) Write the system of inequalities that describes the constraints on the number of each type of wood chipper produced. (Let x represent the number of deluxe models, and let y represent the number of economy models.)
Answers
Answer:
3x + 2y ≤ 30
0.5x + y ≤ 9
Step-by-step explanation:
Number of deluxe model = x
Number of economy models = y
Assembly hours :
Maximum hours = 30
Deluxe model = 3 hours
Economy model = 2 hours
3x + 2y ≤ 30
Painting :
Maximum hours = 9
Deluxe model = 1/2 = 0.5 hours
Economy model = 1 hours
0.5x + y ≤ 9
Therefore the inequality constraints are:
3x + 2y ≤ 30
0.5x + y ≤ 9

Your answer
Answers
Answer:
x = 4
Step-by-step explanation:
3x -5 = -2 + 9
-2 + 9 = 7 so now its 3x - 5 = 7
add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12
divide 12 ÷ 3 = 4
x = 4
3x - 5 = -2 + 9
add -2 + 9 and that gives you 7 so now
3x - 5 = 7 you add -5 on both sides but when you switch the -5 over with the 7 is becomes +5 so now you have 3x = 12 since 5 + 7 is 12
then you’ll divide 3 on both sides and that leaves you with x = 4

Answer:
The area would be 153.86
Step-by-step explanation:
Since the diameter is 14, the radius would be 7.
The area is pi times the radius squared.
7 squared is 49.
If your using 3.14 for pi, then its 3.14 times 49.
That gives you 153.86.

Is 1/6 greater or 1/24
Answers
Answer:
yes
Step-by-step explanation:
Answer: 1/6 is greater than 1/24
=========================================================
Explanation:
Let's assume that 1/6 is equal to 1/24 for now. We'll see later this is false.
1/6 = 1/24
1*24 = 6*1 .... cross multiply
24 = 6
The last equation is false, so the first equation is false.
To fix things, we need to replace every equal sign with a greater than sign like so
1/6 > 1/24
1*24 > 6*1
24 > 6
Now each of those three statements are true, since the last statement is true. This shows that 1/6 is greater than 1/24.
----------------
We can take another approach to use the calculator to see that
1/6 = 0.167 approximately
1/24 = 0.042 approximately
We can see that 0.167 is the larger decimal, so 1/6 is the larger fraction.
If you want, you can move the decimal point over 3 spots to the right for each decimal number. So that would mean 0.167 becomes 167, and 0.042 becomes 42. Then it becomes more clear that 167 is the larger value, helping confirm that 0.167 is the larger decimal.

from the 103 wraps sold. How many of the wraps sold were vegetarian?
Answers
Answer:
Step-by-step explanation:
v+2.5c=191.5 and c+v=103, so c=103-v, using this c in first equation gives you
v+2.5(103-v)=191.5
v+257.5-2.5v=191.5
-1.5v=-66
v=44

A term is a group of numbers and variables.
In your expression, there are 3 term: 3k, 10, and 5n^3A coefficient is just the number attached to the variable.
In the term 3k, the first one in your expression, the 3 is the coefficient because it is being multiplied by an unknown, k. There is also another term with a variable in your expression: 5n^3. 5 would be the coefficient because it is being multiplied by an unknown, n, multiplied by itself three timesA constant is just a number.
In your expression, 10 is a constant because it doesn't have a variable, so no matter what the other variables are, that term will always stay 10Hope this helps :)
