Answer:

225

Step-by-step explanation:

To square a number, you simply multiply it by itself.

15² = 15 · 15 = 225

Answer:

i also can't at all

Step-by-step explanation:

This is hard for me

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 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.

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]

Option D. From the question that we have here, we would have it that neither option A or option B would help the Green in order to meet up with the plan that they have.

The house they want to put an addition on is in 18 months. The amount to be saved is $10620, the total amount saved after a year = 6120

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

This is still below the target.

Hence we would conclude by saying that Neither option A nor option B will allow them to meet their goal.

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.

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

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:

Parallel lines never intersect, but they must be in the same plane. The definition does not require the undefined term point, but it does require plane. Because they intersect, perpendicular lines must be coplanar; consequently, plane is not required in the definition.

It would take 3.43 hours to paint living room working together.

In this question, we have been given Fran were to paint her living room alone, it would take her 5 hours. Her sister Wanda could do the job in 8 hours.

We need to find the amount of time required them working together.

Let they need 'x' hours to paint living room together.

So, we get an equation,

1/6 + 1/8 = 1/x

We need to find the value of x.

1/x = (8 + 6) / 48

1/x = 14/48

x = 48 / 14

x = 3.43 hours

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.

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.
