The step by step formula for figuring out a home mortgage is given by the equation: M = P [ i (1 + i )ⁿ ] / [ (1 + i )ⁿ - 1]

A standard mortgage payment means paying back your loan amount and any interest that the bank stated at the time of giving the loan.

It can also include taxes and insurance with your monthly mortgage rate, but this can be calculated separately.

The equation takes into account your total loan payment with the monthly interest rate and the length of time you have to pay off your loan that is the time period. It gives you a fixed monthly mortgage rate.

Therefore, the step by step formula for figuring out a home mortgage is given by the equation: M = P [ i (1 + i )ⁿ ] / [ (1 + i )ⁿ - 1]

Answer: x=-15

Step-by-step explanation:

11=x/-5+8

minus 8 on both sides

3=x/-5

multiply by -5 on both sides

x=-15

Answer:

x = -15

Step-by-step explanation:

Given: 11 = x/-5 + 8

We need to get x by itself to make a formula or get an answer

Step 1: Subtract 8 on both sides

We need to subtract 8 on both sides in order to cancel out the 8 on the right and bring it to the left

so, 11 -8 = x/-5 +8 -8 = 3 = x/-5

Step 2: Multiply by -5

We need to multiply by -5 in order to cancel our the -5 on the right and bring it to the left

so, 3*-5=x/-5*5 = -15 = x

Therefore, x = -15.

smaller number = y

larger number = x

x - y = 69

4y = x + 3

you can solve this using substitution

x = 69 + y

(isolating one of the variables)

4y = 69 + y + 3

(substituting 69 + y for x into the other equation)

4y = 72 + y

3y = 72

y = 24

(simplify)

x - 24 = 69

x = 93

(substituting 24 into one of the original equations)

The second pair represent a unit rate. And the graph is shown.

An ordered pair is a pair made up of two parts that are written inside parantheses and are separated by commas. For instance, the ordered pair (x, y) denotes an ordered pair where "x" is the first member and "y" is the second element. These elements, which can either be variables or constants depending on the context in which they are used, have distinct names.

In an ordered pair, the element order is somewhat significant. It implies that (x, y) may not always be equivalent to (y, x).

When describing a point's location on the coordinate plane with respect to the origin, a coordinate geometry ordered pair is employed.

Hence the graph is attached and the second pair represents the unit rate.

Answer:

172.63

Step-by-step explanation:

First let's write the problem as an expression

56.6% * 305

Let's convert 56.6 to a decimal

0.566% * 305

Now finish by multiplying

0.566% * 305

The two inequalities that can be used to find the solution are x-1 < 3 and x-1 > -3.

The given inequality is 3 + 2|x-1| < 9.

The absolute value |x-1| can be (x-1) or -(x-1).

We need to solve this inequality for this two cases.

So first if |x-1| = (x-1), then,

3 + 2|x-1| < 9

⇒ 3 + 2(x-1) < 9

⇒ 2(x-1) < 6

⇒ x-1 < 3

⇒ x < 4 is the solution.

Now if |x-1| = -(x-1), then,

3 + 2|x-1| < 9

⇒ 3 - 2(x-1) < 9

⇒ -2(x-1) < 6

⇒ -(x-1) < 3  

⇒ x-1 > -3  [When multiplied with (-1), the inequality reverses]

⇒ x > -2 is the solution.

Going through these steps, we can conclude that the two inequalities that can be used to find the solution to the absolute value inequality,

3 + 2|x-1| < 9 are x-1 < 3 and x-1 > -3.

Remember that a year has 12 months, if they are only able to save the above in a year, then in 12 months they cannot meet with the saving target.

Increasing saving by 120 for 18 months = 120 x 18= $2160

Based on the exterior angle theorem, the indicated measures are: t + p = 135°.

In a triangle where an exterior angle is formed outside the triangle by an extended side of the triangle, the exterior angle theorem states that the measure of this exterior angle must be equal to the sum of the two interior angles that are directly opposite this exterior angle.

Angle t and angle p are interior angles of the triangle that are opposite the exterior angle that measures 135 degrees.

This implies that: the sum of angles t and p would be equal to 135 degrees.

At a cost of $3.70, we can buy 7.40 ounces of barley.

Given that,
Barley cost per pound = $8
To determine how many ounces of barley can be bought at a cost of $3.70.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
1 pound  = 16 ounces
since 1 pound = $8
divide both the side by 16
1 / 16 pound  = 8 /16
1 / 16 pound =  $0.5
1 ounce = $0.5 cost
Now,
at 1$ = 2 ounces
multiply both sides by $3.70.
3.70 = 2*3.70 ounces
at $3.70 = 7.40 ounces

Thus, at a cost of $3.70, we can buy 7.40 ounces of barley.

3.0 CUBIC YARDS I WILL NEED TO ORDER TO PUT A 2 INCH THICK LAYER OF TOPSOIL

As a result, the problem gives you the volume of the space you are trying to fill with soil ( 20ft by 24ft by 2 in). Let's measure everything in feet first, and then we can measure the volume in yards. You may acquire a volume of approximately (rounding to two decimal places)80.00  cubic feet by converting 2 inches to feet, or 2/12. Then, to obtain your volume, multiply that by 20 times 24. Since there are 3 feet in 1 yard, we divide this volume in yards by 3, giving us 3.0 cubic yards. You will need 3.0 cubic yards if the business only sells in 1/4 cubic yard increments.
