Solve. h + 11.5 = -11.5

Answers

Answer:

-23

Step-by-step explanation:

h+11.5=-11.5

h=-11.5-11.5

h=-23

you will subtract -11.5 on both sides which leaves h alone on one side

Step-by-step explanation:

subtract 11.5 from both side of equation

h + 11.5 = -11.5

h + 11.5 - 11.5 = -11.5 - 11.5

h + 0 = -23

h = -23

Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?

Answers

Answer:

8 gallons

Step-by-step explanation:

Total gas in the car = 14 gallons

Each hour gas usage = 1.5 gallons

Total hours traveled = 4 hours

Left gas after 4 hours

= 14-1.5(4)

=14-6

=8 gallons

Left gas after t hours

=14-1.5t

Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t

The amount of gas in the tank after driving for 4 hours will be 6 gallons. The amount of gas that is left after t hours will be 14 - 1.5t.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Nayeli is driving on a long road trip. She currently has 14 gallons of gas in her car. Each hour that she drives, her car uses up 1.5 gallons of gas.

The amount of gas in the tank after driving for 4 hours will be

⇒ 1.5 x 4

⇒ 6 gallons

The amount of gas that is left after t hours will be

⇒ 14 - 1.5t

The amount of gas in the tank after driving for 4 hours will be 6 gallons. The amount of gas that is left after t hours will be 14 - 1.5t.

For this exercise we must correct the error of the given fraction, differentiating the properties of addition and multiplication, so:

1)This error occurs frequently because when simplifying in a multiplication or division it cannot be done in the operations of subtraction and addition.

2)As this error is very common, it has probably already occurred. But one way to resolve this is to pay attention and redo the math.

to understand this error we have to:

[tex]\frac{(3)(5)}{3} = 5[/tex]

In the case of multiplication the 3 of the numerator can be simplified with the 3 of the denominator, the other case will be:

[tex]\frac{3+5}{3} = \frac{8}{5}[/tex]

In the case of addition or subtraction, you should always keep the denominator.

Answer:

£67.87

Step-by-step explanation:

(Total increase) = (Original Amount) × (Multiplier)²

Rearrange the equation to find the original amount

(Total increase) ÷ ( Multiplier)² = (Original amount)

To find the Multiplier, add 1 to 3% = 1.03

Substitute what you can

(72) ÷ (1.03)² = Original amount

£67.8669054576 = Original Amount

Round up the number to 2 decimal places since it is British Pounds currency

Give the slope values that are parallel and perpendicular to a slope of 1/4.

Answers

Step-by-step explanation:

Finding the Slopes of Parallel and Perpendicular Lines

How do we know if two distinct lines are parallel, perpendicular or neither? To make that determination, we need to review some background knowledge about slope.

Concept 1: When two points are given, the slope of a line can be algebraically solved using the following formula:

Slope Formula

The slope,mm, of a line passing through two arbitrary points \left( {{x_1},{y_1}} \right)(x  

1

,y  

1

) and \left( {{x_2},{y_2}} \right)(x  

2

,y  

2

) is calculated as follows…

m = (ysub2-ysub1)/(xsub2-xsub1)

Concept 2: When a linear equation is given, we can find the slope by transforming it into the Slope-Intercept Form. The value of slope will stand out, as it is the coefficient of the linear term (xx-term).

Slope-Intercept Form of a Line

The linear equation written in the form y = mx + by=mx+b is in slope-intercept form where:

m is the slope, and b is the y-intercept

Now, suppose we have two distinct and nonvertical lines, {\ell _1}ℓ  

1

 and {\ell _2}ℓ  

2

 in Slope-Intercept Form.

Line 1:

line 1 → y=msub1x+b

Line 2:

line 2 → y = msub2x+b

Parallel Lines: The lines are parallel if their slopes are equal or the same. That means

Equal Slopes:

msub1 = msub2

Graph:

graph showing line 1 and line 2 parallel on the coordinate plane.

Perpendicular Lines: The lines are perpendicular if their slopes are opposite reciprocals of each other. Or, if we multiply their slopes together, we get a product of - \,1−1. These lines intersect at a ninety-degree angle, 90°.

Opposite Reciprocal Slopes:

msub1 = -(1/msub2)

Product of Slopes:

msub1× msub2 = -1

Graph:

graph showing line 1 and line 2 perpendicular to each other on the coordinate plane.

Examples of How to Find the Slopes of Parallel and Perpendicular Lines

Example 1: Line 1 passes through the points \left( {1,3} \right)(1,3) and \left( {4,9} \right)(4,9), while line 2 passes through \left( {2,5} \right)(2,5) and \left( { - \,2, - \,3} \right)(−2,−3). Tell whether these lines are parallel, perpendicular, or neither.
