Step-by-step explanation:

Hello!

For this question it's important to know what form an expression takes, which is essentially a group of "things" (such as x, y, and numbers) that don't necessarily equal anything else, that would be an equation

In other words, an expression is a mathematical statement that does not include an = sign.

An equation to model this situation is M = t/3 + 3, which is shown in the graph attached below.

In order to solve this word problem, we would assign variables to the amount of time taken by Rick's bus ride and Matt's bus ride to school, and then translate the word problem into algebraic equation as follows:

Therefore, translating the word problem into an algebraic equation, we have the following;

M = 1/4(t) + 3

M = t/3 + 3

Based on the graph (see attachment) which models the relationship between the amount of time taken by Rick's bus ride and Matt's bus ride, we can logically deduce that the slope of the graph is 1/4 and the y-intercept is equal to 3.

the answer is 148 the reason is two angle interception

Step-by-step explanation:

The angle on top of x(x+4) is equal to 148.

The angle at x(x+4) = 180 -148 = 32

[tex]x(x + 4) = 32 \\ {x}^{2} + 4x = 32 \\ {x}^{2} + 4x - 32 = 0 \\ (x - 4)(x + 8) = 0[/tex]

What is convincing evidence?

The proof is sufficient evidence or a sufficient argument for the truth of a proposition. The concept applies in a variety of disciplines, with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent.

if our test statistic is: positive and greater than the critical value, then we have sufficient evidence to reject the null hypothesis and accept the alternative hypothesis. positive and lower than or equal to the critical value, we must accept the null hypothesis.

Answer:

156

Step-by-step explanation:

36*3=108

8*-6=-48

108-(-48)=156

The solution of the expression 36(3) - 8(-6) will be 156.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 36(3) - 8(-6). the expression will be solved as below,

E = 36(3) - 8(-6)

E = 108 - ( -48 )

E = 108 + 48

E = 156

Hence, the solution will be 156.

Answer:

Step-by-step explanation:

This is a special right triangle with side lengths 5-12-13 respectively.

If we can't remember the lengths we can use the following formula to calculate the lentgh of hypotenuse:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

the sum of square measure of both legs is equal to the square measure of hypotenuse

[tex] {5}^{2} + {12}^{2} = {c}^{2} [/tex]

25 + 144 = c^2

169 = c^2 find the root of both sides

13 = c, hypotenuse.

Situations a and c can represent a proportional relationship. Options a and c are correct.

It is defined as the relationship between two quantities as one quantity increases the other quantity also increases and vice versa.

The following situations are found to represent proportionality using the concept of proportionality:

A) The total amount a babysitter makes who earns $10 an hour for babysitting r hours.

Answer:

n = 8

Step-by-step explanation:

to solve this equation you must first isolate the variable

that is n

so first

add 2n to both sides to get rid of n on one of the sides

-4n + 2n + 14 = -2 - 2n + 2n

-2n + 14 = -2

now subtract 14 to both sides to isolate n

-2n + 14 - 14 = -2 - 14

-2n = -16

now divide everything by -2 to isolate n completely

(-2n)/(-2) = (-16)/(-2)

n = 8

that is your answer

Answer:

[tex]\boxed{\sf n=8}[/tex]

Step-by-step explanation:

[tex]\sf -4n+14=-2-2n[/tex]

Subtract 14 from both sides:-

[tex]\sf -4n+14-14=-2-2n-14[/tex]

Simplify:-

[tex]\sf -4n=-2n-16[/tex]

Add 2n to both sides:-

[tex]\sf -4n+2n=-2n-16+2n[/tex]

Simplify:-

[tex]\sf -2n=-16[/tex]

Divide both sides by -2:-

[tex]\sf \cfrac{-2n}{-2}=\cfrac{-16}{-2}[/tex]

The amount after four years is £2649.79 .

Now we know that we need to obtain the rate for the compounding of the money and we need to recall that for the amount, we have;

A = P(1 +r/n)^nt

A = amount

P = principal

r = rate

n = number of times compounded

t = time

For one year in which the interest is compounded annually;

2496.96 = 2448(1 + r)^1

2496.96/ 2448 = (1 + r)
