The value of the equation 7a = 28 is a = 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

7a = 28

On simplifying the equation , we get

Divide by 7 on  both sides of the equation , we get

a = 28 / 7

a = 4

Therefore , the value of a is 4

Hence , The value of the equation 7a = 28 is a = 4

Answer: three x plus 4 y raised to the power of three

Step-by-step explanation:

By using the fact that all the triangles are equilateral, we will see that AB = 32 units.

Here we have a figure made of equilateral triangles. Remember that all the sides of an equilateral triangle have the same measure.

Now we can see that FE = 16, then with that we can conclude that each segment of two consecutive vertices also measures 16 unints.

Now, we can write AB as:

AB = AD + DB

And we know that:

AD = 16 units

DB = 16 units.

Then:

AB = 16 + 16 = 32 units

That is the length of segment AB.

The product of -1.8 and = -1.8 x ?

3 more than a number = 3 + n

The product of -1.8 and 3 more than a number = -1.8(3 + n)

Is the same as 1/10 = equals (equal sign) 1/10

Full Equation: -1.8(3 + n) = 1/10

Steps to solve:

1. Divide both sides by -1.8 (or - 9/5)

(3 + n) = 1/10 x -5/9

3 + n = -5/90

2. Subtract 3 from both sides

n = -5/90 - 270/90

n = -30 5/9

The best answer would be that 2x greater then zero which satisfy the condition.

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex at (0,0). The range is from the y-coordinate of the vertex to positive infinity.

If x ≥ 0, then we need to determine the value of x+|x|

Since {x | x < 0} and {x | x > 0} which is no number less than zero and greater than zero at the same time.

Here we need to add that is;

x+|x|  = 2x

Therefore, in conclusion we get that 2x is greater then zero which satisfy the condition.

The number of bananas are 6 and the number of peaches are 4.

What is system of equations?

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.

Given:

Hua and her children went into a grocery store and she bought $9

worth of bananas and peaches.

Each banana costs $0.50 and each

peach costs $1.50. She bought a total of 10 bananas and peaches altogether.

Let

B = number of bananas

P = number of peaches

0.5 * B = cost of number of bananas purchased

1.5 * P = cost of number of peaches purchased

So,

B + P = 10                 ..(1)

0.5B + 1.5P = 9         ..(2)

From equation (1),

B = 10 - P        ..(3)

Plug value of B in equation (2),

0.5(10 - P) + 1.5P = 9

5 - 0.5P + 1.5P = 9

5 + P = 9

P = 4

Plug P = 4 in equation (3)

B = 10 - 4

B = 6

Hence, the number of bananas are 6 and the number of peaches are 4.

Yes, natural numbers are an example of closed under addition.

Natural numbers are closed under addition and also multiplication. The addition of two or more natural numbers results in always a natural number.  while for the case of subtraction and division, natural numbers don't obey the closure property, which means dividing or subtracting two natural numbers might not give a natural number. for example, considering two numbers 5 and 7, when we add both of them the result we come up with is 12, which is also a natural number.

Answer: It will take about 8.5 years for the balance of the savings account to reach $3827.25.

Step-by-step explanation:

To find the number of years it will take for the balance of the savings account to reach $3827.25, we can set up the following equation:

$3500 * (1 + 0.011 * t) = 3827.25$

We can then solve for t, the number of years, by dividing both sides of the equation by 3500 and then rearranging the terms to get t by itself:

$t = \frac{3827.25 - 3500}{3500 * 0.011}$

Next, we can plug in the given values and solve for t to find the number of years it will take for the balance of the account to reach $3827.25:

$t = \frac{3827.25 - 3500}{3500 * 0.011} = \frac{327.25}{38.5} = 8.5$

Therefore, it will take about 8.5 years for the balance of the savings account to reach $3827.25.

The conditions are not met by the extreme outliers, hence we are unable to draw inferences based on the statistical output presented above.

So, option e is correct.

The null hypothesis, often known as H₀, is the assertion that there is no difference between two sets of data or variables under analysis, or that there is no relationship between them. Because there is no underlying causative relationship, the null hypothesis holds that any experimentally detected difference is merely the result of chance; therefore, the name "null."

We can create a z-test hypothesis by assuming that the amount of rain produced by thunderheads follows a distribution that is nearly normal:

300 acre feet is the null hypothesis for the average quantity of rain that thunderheads produce on their own without fertilizing the clouds.

Alternative Hypothesis: The amount of rain that thunderheads often produce by seeding the clouds is greater than 300 acre feet.

This test has a right tail.

Margarite must deposit $3174 as the principal in her account.

The addition of interest to the principal of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. It occurs when interest is reinvested, added to the lent capital instead of being paid out, or the borrower is required to pay it, resulting in the next period's interest being generated on the principal amount plus any accumulated interest. Finance and economics both use compound interest frequently.

In contrast to simple interest, which does not compound since past interest is not added to the current period's principal, compound interest allows for the accumulation of interest from prior periods.

As given:

42000 dollars are required for the journey to Japan.

Let P be the account's principal deposit.

Interest rates are 3.5% each day, compounded.

The duration is 8 years.

4200=P(1+(3.5/365×100))³⁶⁵⁽⁸⁾

4200=P(1.00009589)²⁹²⁰

4200=P×1.323110

P=4200/1.323110

P=3174.33
