Tony has $300 in his bank account. He takes out $10 each week for "W" weeks. After "W" weeks he has "D" dollars left in his bank account. Write an equation that represents the amount of money left in his bank account after "W" weeks.
Answer:
The Equation :
D = 300 - 10W
Step-by-step explanation:
We are told in the above question that:
Tony has $300 in his bank account. He takes out $10 each week for "W" weeks.
Where W = number of weeks
Our Equation is written as
Total amount in the bank account - $10 × W
= $300 - $10 × W
The Equation is given as
D = 300 - 10W

BASIC RULES FOR ROUNDING
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

The LCM of two numbers is 14 times their HCF. The sum of LCM and HCF is 600. If one number is 280, then find the other number.
Given:
The LCM of two numbers is 14 times their HCF.
The sum of LCM and HCF is 600.
One number is 280.
To find:
The other number.
Solution:
Let HCF of two numbers be x.
The LCM of two numbers is 14 times their HCF.
LCM = 14x
The sum of LCM and HCF is 600.
[tex]14x+x=600[/tex]
[tex]15x=600[/tex]
[tex]x=\dfrac{600}{15}[/tex]
[tex]x=40[/tex]
So, HCF = 40 and the LCM is
[tex]LCM=14(40)[/tex]
[tex]LCM=560[/tex]
We know that, if a and b are two numbers, then
[tex]a\times b=LCM(a,b)\times HCF(a,b)[/tex]
One number is 280.
[tex]280\times b=560\times 40[/tex]
[tex]b=\dfrac{560\times 40}{280}[/tex]
[tex]b=2\times 40[/tex]
[tex]b=80[/tex]
Therefore, the other number is 80.

Find the solution to the system of equations below.
2y = 2x - 8
2x + y = 5
Answer:
The solution to the system of equations is:
(x, y) = (3, -1)The graph is attached below.
Step-by-step explanation:
Given the system of equations
[tex]2y = 2x - 8[/tex]
[tex]2x + y = 5[/tex]
Let us solve the system of equations using the elimination method
[tex]\begin{bmatrix}2y=2x-8\\ 2x+y=5\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}2y-2x=-8\\ y+2x=5\end{bmatrix}[/tex]
Multiply y + 2x = 5 by 2: 2y + 4x = 10
[tex]\begin{bmatrix}2y-2x=-8\\ 2y+4x=10\end{bmatrix}[/tex]
subtracting the equations
[tex]2y+4x=10[/tex]
[tex]-[/tex]
[tex]\underline{2y-2x=-8}[/tex]
[tex]6x=18[/tex]
solve 6x = 18 for x
[tex]6x=18[/tex]
Divide both sides by 6
[tex]\frac{6x}{6}=\frac{18}{6}[/tex]
simplify
[tex]x=3[/tex]
For 2y - 2x = -8 plug in x = 3
[tex]2y-2\cdot \:3=-8[/tex]
[tex]2y-6=-8[/tex]
Add 6 to both sides
[tex]2y-6+6=-8+6[/tex]
Simplify
[tex]2y=-2[/tex]
Divide both sides by 2
[tex]\frac{2y}{2}=\frac{-2}{2}[/tex]
Simplify
[tex]y=-1[/tex]
Therefore, the solution to the system of equations is:
(x, y) = (3, -1)The graph is attached below.

Answer:
The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train. If the two trains are 400 miles apart after 2 hours, what is the rate of the eastbound train?
Answer:
Rate of the Eastbound train is 93 mph.
Step-by-step explanation:
Let the speed of the Eastbound train = x miles per hour
And the speed of the West bound train = y mph
Eastbound train travels 14 mph slower than the westbound train,
So the equation will be,
y - x = 14 ----------(1)
If these trains are 400 miles apart after 2 hours,
Distance traveled by the Eastbound train = Speed × Time
= 2x miles
Distance traveled by the Westbound train = 2y miles
Trains are 400 miles apart after 2 hours,
So the equation will be,
2y + 2x = 400
x + y = 200 ----------(2)
By adding equation (1) and equation (2)
(y - x) + (x + y) = 14 + 200
2y = 214
y = 107 mph
From equation (1)
107 - x = 14
x = 107 - 14
x = 93 mph
Therefore, rate of the Eastbound train is 93 mph.

Step-by-step explanation:
Maya, Ahmad, and Joe served a total of 75 orders Monday at the school cafeteria. Joe served 2 times as many orders as Maya. Ahmad served 5 fewer orders
than Maya. How many orders did they each serve?
Total number of orders served by Maya, Ahmad and Joe on Moday = 75
Let the number of orders Maya served be x.
Then :
Number of orders Joe served = 2x
Number of orders Ahmad served = x - 5
This can be written in an equation as :
[tex] \tt \: 2x + x - 5 + x = 75[/tex]
[tex] = \tt 4x - 5 = 75[/tex]
[tex] = \tt 4x = 75 + 5[/tex]
[tex] = \tt 4x = 80[/tex]
[tex] = \tt \: x = \frac{80}{4} [/tex]
[tex] = \tt \: x = 20[/tex]
Which means :
Number of orders Joe served :
= 2 × 20
= 40
Thus, Joe served 40 orders.
Number of orders Maya served = 20
Number of orders Ahmad served :
= 20 - 5
= 15
Thus, Ahmad served 15 orders.
Therefore, Maya served 20 orders Ahmad served 15 ordersJoe served 40 orders.FITNESS CLASSES Toshelle wants to take strength training classes at the community center. She has to pay a one-time enrollment fee of $ 25 to join the community center, and then $ 45 for each class she wants to take. Write an equation in slope-intercept form to represent the cost of taking x classes.
Answer:
y = 45x + 25
Step-by-step explanation:
Slope-intercept equation/form:
y = mx + b
________________________
x is the amount of classes that Toshelle will take and each class costs $45.
So, you multiply them by one another to get:
45x
_________________________
Additionally, there is a one-time payment of $25.
So, you add 25 to the cost to get:
+25
__________________________
y is the total amount of money Toshelle has to pay.
Therefore, you place 45x and +25 into a slope-intecept equation/form to get:
y = 45x + 25

What is 5/6 of 18? Its a fraction.
Answer:
Step-by-step explanation:
5/6 x 18 = 5 x 18/6 = 5x3 = 15
The requried, fraction 5/6 of 18 is equal to 15. In other words, if you take 5/6 of 18, you get 15.
To find 5/6 of 18, we set up the expression as follows:
(5/6) * 18
To multiply a fraction by a whole number, we simply multiply the numerator (the top number) of the fraction by the whole number. The denominator (the bottom number) remains the same. In this case, we have:
(5 * 18) / 6
Now, we multiply the numerator 5 by the whole number 18:
5 * 18 = 90
So, we have:
(90) / 6
Simplify the fraction.
To simplify the fraction, we divide the numerator (90) by the denominator (6):
90 / 6 = 15
Therefore, 5/6 of 18 is equal to 15. In other words, if you take 5/6 of 18, you get 15.
