Answer:
The value of the equation for y is [tex]y=\frac{-\pi+7x}{2}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex] \pi=7x-2y[/tex]
We need to solve the equation for y.
Subtract 7x to both sides of the equation.
[tex] \pi-7x=7x-7x-2y[/tex]
[tex] \pi-7x=-2y[/tex]
Divide both the sides by -2.
[tex] \frac{\pi-7x}{-2}=\frac{-2y}{-2}[/tex]
[tex]y= \frac{\pi-7x}{-2}[/tex]
[tex]y=\frac{-\pi+7x}{2}[/tex]
Hence, the value of the equation for y is [tex]y=\frac{-\pi+7x}{2}[/tex].

The change in the value of an account when given to the nearest dollar
The net change in the value of the account, when rounded to the nearest dollar, is $550.
To find the net change in the value of the account, you would sum up the amounts deposited, subtract the amounts withdrawn, and add the interest earned:
Net change = (Deposits - Withdrawals) + Interest earne
Net change = ($500 - $250) + $300
= $250 + $300
= $550
Therefore, the net change in the value of the account, when rounded to the nearest dollar, is $550.
The probable question maybe:
"What is the net change in the value of an investment account after depositing $500, withdrawing $250, and earning $300 in interest, when rounded to the nearest dollar?"

How to simplify 6/18
The simplified form of [tex]\frac{6}{18}[/tex] is [tex]\frac{1}{3}[/tex].
To simplify the fraction [tex]\frac{6}{18}[/tex], follow these steps:
Find the greatest common divisor (GCD) of the numerator and the denominator. The numerator is 6 and the denominator is 18. The greatest common divisor of 6 and 18 is 6.
Divide both the numerator and the denominator by their GCD.
When we divide the numerator 6 by 6, we get [tex]\frac{6}{6} = 1[/tex].
When we divide the denominator 18 by 6, we get [tex]\frac{18}{6} = 3[/tex].
Write the simplified fraction: After dividing both parts by 6, the fraction [tex]\frac{6}{18}[/tex] simplifies to [tex]\frac{1}{3}[/tex].
Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold?
Answer:
There are 15 boxes of 10 oz boxes
Step-by-step explanation:
Let the number of boxes of 10 oz = x
and let the number of boxes of 16 oz = y
By the statement
"Total number of boxes sold is 24"
Equation for the statement will be
x + y =24 ---------------(1)
By the statement
"she collected $97.50 while rate of 10 oz box is $3.50 and rate of 16 oz box is $5.00."
Equation for the statement will be
1.5x + 5y = $97.50 ------------(2)
From equation (1) we put the value of y = 24 - x in equation (2)
1.5x + 5(24 - x) = 97.50
1.5x + 120 - 5x = 97.50
-3.5x = 97.50 - 120
3.5x = 22.50
x = [tex]\frac{22.5}{1.5}[/tex]
x = 15
Therefore, number of 10 oz boxes is 15.

What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Let's simplify the left-hand side first:
4y - 7 + 2y = 6y - 7
Now let's simplify the right-hand side:
-3(y - 1) - 1 = -3y + 2
Now we can substitute these simplified expressions back into the original equation and solve for y:
6y - 7 = -3y + 2
Adding 3y to both sides, we get:
9y - 7 = 2
Adding 7 to both sides, we get:
9y = 9
Dividing both sides by 9, we get:
y = 1
Therefore, the solution is y = 1.

A helicopter is flying at a altitude of 785 feet.It descends 570 feet, and then ascends 595 feet.
Answer:
810 feet.
Step-by-step explanation:
We are supposed to find the final altitude of the helicopter.
We have been given that a helicopter is flying at a altitude of 785 feet, this means that altitude of helicopter is positive.
Further, the helicopter descends 570 feet, this means that altitude of helicopter is [tex]-570[/tex].
Finally, the helicopter ascends 595 feet, this means that altitude of helicopter is [tex]595[/tex].
[tex]\text{Helicopter's final elevation}=785\text{ ft}-570\text{ ft}+595\text{ ft}[/tex]
[tex]\text{Helicopter's final elevation}=810\text{ ft}[/tex]
Therefore, the final elevation of helicopter is 810 feet.

Fred Salmon purchased six $1,000 bonds at 92. The bonds pay 6.5%. What was the cost of the bonds? What was the total annual interest? What is the yield?
Answer:
Cost:$ 920 each or $5,520
Total annual interest: $65 per bond and $390 total
Yield: 7.06%
Step-by-step explanation:
The cost of the bonds is given by the multiplication of the value of the bonds by 92 and divided by 100:
1000*92/100=920
So the cost of each bond would be $920
Then the interest that is payed by the bonds is based on its value which is $1000, so he receives 65 dollars per bond a year, that multiplied by the 6 bonds is equal to $390.
The yield is the real money paid to return interest rate relation, so you just have to take the percentage if 5,520 is the 100, how much is $390=
5520/100=390/x
x=39000/5520=7.06%
Write the fraction 8/9=as an equivalent fraction with the given denominator 18
The equivalent fraction of 8/9 with the denominator 18 is 16/18.
Explanation:To write the fraction 8/9 as an equivalent fraction with the given denominator 18, we have to find a number that we multiply by 9 (the original denominator) to get 18. This number, in this case, is 2. What we do to the bottom of a fraction, we should also do to the top, therefore we would also multiply the numerator (8) by the same number (2). So, the equivalent fraction is 8 * 2 / 9 * 2 = 16 / 18.
