What is the value of x?
edge2020

Answers

Answer 1

Answer:

95⁰

Step-by-step explanation:

next time you want to figure this out, here's how

- they are supplementary angles, so you just subtract 45⁰ from 180⁰

180-45=95

so, you would get the answer 95⁰

for next time, you might not have as much information as you do in this equation so be careful

hope this helps!

Answer 2

Answer:

Step-by-step explanation:

Since this is supplementary, these two angles add up to 180 degrees. Therefore:

180 - 45 = 135

135 = 2x - 5

140 = 2x

x = 70

Which graph shows a constant of proportionality of 2?

Answers

Answer:

Im pretty sure its C

Step-by-step explanation:

Hope you get it right! :)

The constant of proportionality of a line is also referred to as its slope. The graph shows a constant of proportionality of 2 is the Graph C

Constant of proportionality

The constant of proportionality of a line is also referred to as its slope. Hence according to the question, we are to determine the line that has a slope of 2.

The formula for calculating slope of a line is expressed as:

Slope = y2-y1/x2-x1

Using the graph with coordinate points (3, 6) and (1, 2). The slope of the line is expressed as:

Slope = 2-6/1-3
Slope = -4/-2
Slope = 2

Hence the graph shows a constant of proportionality of 2 is the Graph C

Which equation represents a line that passes through the two points in the table? x3,6 y 1,6

Answers

The lines is represented by (D)

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides.

As, the solution given:

put x=3

y-1 = 0

y=1

Similarly, x= 6

y-1= 5/3 * (3)

y-1 = 5

y=6

Hence, the lines represent y-1 = 5/3 ( x- 3)

7.82 change the decimals to fractions reduced to lowest terms.

Answers

Answer:

7.82 = 391

= 741

as a fraction

To convert the decimal 7.82 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

7.82 = 7.82

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

7.82

= (7.82 × 100)

(1 × 100)

= 782

100

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(782,100) = 2. So,

(782÷2)

(100÷2)

= 391

when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 782

100

is also equal to 741

when expressed as a mixed number.

a) whatever is in the bracket you substitute into x.

c(100) = (1.25*100) + 2175

= 125 + 2175

= 2300

Another exmaple: if it says c(2 + x) then you substitute that into x

→ 1.25(2 + x) + 2175 (and then expand that)

b) A physical interpretation of this could be:

A company that manufactures dishwashers is testing their latest product to see how long it takes to cool down once a cycle is complete. The function, f(x) = 360 - 15x, represents the cooling cycle, where x is equal to the number of minutes and f(x) is equal to the temperature of the dishwasher after x minutes.

Answers

Step-by-step explanation:

Given that the function for the temperature of the dishwasher is

f(x) = 360 - 15x

We are told that x represents the number of minutes it takes to cool down.

with a given/known value of x we can predict the temperature of the dishwasher.

Say x=12 minutes, we can tell what the temperature will be after 12 minutes

by plugin in the value of x=12 in the expressions for the temperature

f(x) = 360 - 15(12)

f(x) = 360 - 180

f(x) = 180

The temperature after 12 minutes will be 180°

4. Which is NOT a way in which thermal energy is transferred? A. Conduction , B. Convection , C. Radiation , D. Sublimation

WILL MARK BRAINLIEST!!

Answers

Answer:

Convection

Step-by-step explanation:

Conduction means the heat energy is being transferred .Hence its not the ansRadiation is a process happened in radioactive elements like radium,uranium etc by which they release beta or alpha particles.Sublimation happens like a solid converted to gas or gas converted to solid directly.

The correct option is C Radiation.

Conduction means transfer of energy (heat) arising from temperature differences between adjacent parts of a body.

Convection is the transfer of thermal energy by the physical movement of fluid (liquid, gas, or plasma) from one location to another.

Radiation is an electromagnetic radiation that is emitted by a body as a result of its temperature. All objects with a temperature above absolute zero emit thermal radiation in a spectrum of wavelength.

Sublimation is the process of changing a solid into a gas without passing through the liquid phase. To sublime a substance, a certain energy must be transferred to the substance via heat (q) or work (w).

Hence from all the above definitions it is clear that every phenomenon except radiation transfer some amount of thermal energy.

Hence through Radiation thermal energy is not transferred.

Which value of x satisfies the equation
5/6 (3/8 - x)
= 16

Answers

Answer:

[tex]x = - 18.825[/tex]

Step-by-step explanation:

[tex] \frac{5}{6}( \frac{3}{8} - x)

= 16 \\ \frac{(5)(3)}{(6)(8)} - \frac{5x}{6} = 16 \\ 15 - 40x = 768\\ 40x = 15 - 768\\ x = - 18.825[/tex]

The value of x for the equation to be equal is- 40/753

Solution to linear equation

Given the linear equation expressed as:

5/6 (3/8 - x) = 16

Open the parenthesis

5/16 - 5/6x = 16

Collect the like terms

-5/6x = 16 - 5/16
-5/6x = 251/16

Cross multiply

1506x = -80
x = -80/1506
x = -40/753
Hence the value of x for the equation to be equal is- 40/753

how do you combine like terms

Answers

Answer: you add them up

Step-by-step explanation:

Explanation:

Combining like terms is commonly used to solve algebraic expressions. Like terms are those species or variables that are the same in any algebraic representation.

Different mathematical operations can be performed on like species. We can add, divide, multiply, subtract, factorize, etc those terms.

Take for example;

Solve;

5x + 3 = 4x + 6

To solve this simply collect the like terms;

5x and 4x, 3 and 6 are like terms

5x - 4x = 6 - 3

x = 3

This is one way of solving problems by collecting like terms.
