Answer: 1.5x + 12.3

Step-by-step explanation:

(3x + 5.3) + (7 - 1.5x)

Since this is not multiplication, try arranging the equation so like terms are together.

3x - 1.5x + 5.3 + 7 =

Combine like terms by adding or subtracting.

3x - 1.5x + 5.3 + 7 = 1.5x + 12.3

Answer:

(5, 0)

Step-by-step explanation:

The slope of the first line is -(-1 / 1) = 1.

The slope of the second line is -(3 / 5) = -3/5.

Since the lines have different slopes, they intersect at a single point. Therefore, there is only one solution. To find it, solve the system of equations.

Using elimination, multiply the first equation by 3 and add it to the second.

-3x + 3y = -15

3x + 5y = 15

-------------------

8y = 0

y = 0

Using substitution, find x:

-x + 0 = -5

x = 5

The solution is (5, 0).

Answer:

119 eggs

Step-by-step explanation:

To start off, we know that this number has to be of some multiple of 7. Because if the eggs are taken out 7 at a time, and no eggs are left over, then the total number of eggs can be divisible by 7. Because there is however a multiple if you take out the eggs 2-6 times, there are eggs left over. The smallest multiple of 7 we can test is simply 7. To check, we can start with dividing 7 by 6 and getting a remainder of 1 instead of 5. So we know that 7x1 doesn't work.

The next smallest multiple of 7 that isn't multiplied from 2-6 is 7x7 to get 49. from here we can check that 49/6 = 8 r1 (r meaning remainder). So we know that 7x7 can't work. From here, the next smallest number would be 7x11.

7x11 = 77. 77/6 is 12 r5. This so far looks good. Now we can try 5. 77/5 = 15 r2. This doesn't work, so we try the next largest number which is 7x13 which is 91.

91/6 = 15 r1 which doesn't work. Next we try 7x17 which is 119. 119/6 is 19 r5 (looks good), 119/5 = 23 r4 (looks good), 119/4 is 29 r3, 119/3 is 39 r2, and 119/2 is 59 r1! Which means our answer is that the least number of eggs in the basket is 119.

It will take 5.01 years for Mantago to repay the money that he would borrow.

Assume that it will take 't' years for Mantago to repay the money that he would borrow.

Here, we use monthly cashflow formula:

The equation must satisfies the Kent calculation is k² - 8k + 12 = 0

The term equation in math is called as a mathematical expression that contains an equals symbol.

Here we have given that Kent multiplies both sides of the equation below by an expression.

And then he moves all the terms to one side of the equal sign in the resulting equation.

Here we have the given equation is

=> k+12/k= 8

When we multiply both sides by k.

=> k² + 12 = 8k

Now we have to subtract 8k from both sides to move all the terms to one side of the equal sign then we get

=> k² + 12 - 8k = 0

Hence the required equation is k2 - 8k + 12 = 0.

Andrew's initial deposit will grow to about $543 in 7 months.

You can use the formula A = P * e^(rt) to calculate this, where A is the final amount, P is the initial deposit, r is the interest rate, and t is the time in years. The equation for "continual" growth (or decay) is A = Pert, where "A", is the ending amount, "P" is the beginning amount (principal, in the case of money), "r" is the growth or decay rate (expressed as a decimal), and "t" is the time (in whatever unit was used on the growth/decay rate).

A = P * e^(rt)

Plug in the given values:

A = $543

P = $500

r = 0.065 (6.5% expressed as decimal)

Solving for t:

t = ln(A/P) / r

t = ln(543/500) / 0.065

t = 0.07 ( 7 months)\

Therefore, Andrew's initial deposit will grow to about $543 in 7 months.

Step-by-step explanation:

There are 7!/3! ways for 8 people to sit around a circular table if Alice, Bob, and Eve do not want to sit next to each other.

Rotation is the process of rotating an object in two or three dimensions around an axis. This axis can be a point in space, a line, or a plane. Rotation can also refer to a continuous change of direction, such as the rotation of the Earth around its axis. Rotation can be described using terms such as clockwise, counterclockwise, and angular velocity. Rotation can also be described using mathematical equations, such as Euler's rotation theorem. Rotation can be used to create symmetry in design, or to create motion in an animation.

This is because we can pick any of the 7 people to be seated first, then any of the 6 people to be seated second, then any of the 5 people to be seated third, and so on. However, since Alice, Bob, and Eve do not want to sit next to each other, we must divide the 7! by 3! to account for the fact that the order in which Alice, Bob, and Eve are seated does not matter. The 3! accounts for the fact that we could arrange the three of them in 3! = 6 different orders. Therefore, the total number of ways for 8 people to sit around a circular table if Alice, Bob, and Eve do not want to sit next to each other is 7!/(3!) = 840 ways.

Using mathematical operations, we know that Bakery B makes 209/28 more cake than Bakery A per hour.

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.

The operation's arity is determined by the number of operands.

Scalars in MATLAB can be multiplied, divided, added to, subtracted from, multiplied by, and have exponents applied to them.

These operators can be used to arrange calculations involving vectors and matrices in a straightforward manner.

So, bakery A:

4 1/4 cake in 4 hours.

16+1/4

17/4 cake in 4 hours

Bakery B:

11 5/7 cake in 3 hours:

77*5/7

82/7 cake in 3 hours

Then, Bakery A: 17/4 * 7/7 =  119/28

Bakery B: 82/7 * 4/4 =  328/28

More, cake by Bakery B:
328/28 - 119/28

The area of a regular octagon inscribed in a circle of radius 4 meters is 45.255 square meters. So, option C is correct

An octagon is a polygon with 8 sides, and a regular octagon has all sides of equal length. To find the area of a regular octagon inscribed in a circle of radius 4 meters, we can use the formula:

Area = (2 * (4^2) * (1 + sqrt(2))) / (4 * tan(pi/8))

Plugging in the values we get:

Area = (2 * (4*cos(pi/8))^2 * (1 + sqrt(2))) / (tan(pi/8)) = 16 * (1 + sqrt(2)) * (sqrt(2) / sqrt(2+ sqrt(2)))

        = 8 * 1/2 * 4 * 4 * sin45°

The setup cost for printing the math workbooks, given the printed cost of the books, is $ 1, 800

The setup cost for printing the math workbooks is a fixed cost which means that it will not change regardless of the number of books that are printed.

Since we know that 1, 000 books are printed to be $ 14, 300 and that 5, 000 books cost $ 64, 300, we can find the cost of the books without the setup cost to be :

= Difference in cost of books / ( Difference in number of books )

= ( 64, 300 - 14, 300 ) / ( 5, 000 - 1, 000 )

= 50, 000 / 4, 000
