What is the solution set for StartAbsoluteValue 4 minus StartFraction x over 2 EndFraction EndAbsoluteValue = 8?
A.x = negative 24 and x = negative 8
B.x = negative 24 and x = 24
C.x = negative 8 and x = 8
D.x = negative 8 and x = 24

The solution to the set is .x = negative 8 and x = 24.

What is Absolute value?

The separation of a number from a number line's origin is referred to as a number's absolute value. It is denoted by the symbol |a|, which specifies the size of any integer 'a'. Any integer's absolute value, regardless of its sign or whether it is positive or negative, will be a real number. The modulus of a, which is how two vertical lines |a| are used to symbolise it.

Given:

|4 - x/2| = 8

So, there are two possibilities

4- x/2 = 8  or 4 - x/2 = -8

-x/2 = 8-4 or -x/2 = -8-4

-x/2 = 4  or -x/2 = -12

x= -8 or x= 24

Hence, the solution to the set is .x = negative 8 and x = 24

Last month, Harri drove 850miles in his car. His car's fuel consumption is 45.6 miles per gallon petrol cost £1.09 per litre given that 8 pints=1 gallon work out how much Harri spent on fuel last month

Answers

Using proportions, it is found that Harri spent £76.91 on fuel last month.

What is a proportion?

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations, especially multiplication and division with the rates.

For this problem, we have that Harri drove 850 miles with a rate of 45.6 miles per gallon hence the number of gallons that Harri used is given as follows:

850/45.6 = 18.64 gallons.

Each gallon is equivalent to 3.78541 liters, hence the number of liters that Harri used is given as follows:

18.64 x 3.78541 = 70.56 liters.

The cost per liter was of £1.09, hence the amount that Harri spent during the last month is given as follows:

70.56 x 1.09 = £76.91.

Mina tiene \dfrac{4}{5} 5 4 ​ start fraction, 4, divided by, 5, end fraction de la harina necesaria para hacer una hogaza. Se necesita la misma cantidad de harina para hacer 111 hogaza que para hacer 121212 panes. ¿Cuál es el mayor número de panes que Mina puede hacer con la harina que tiene?

Answers

Answer:

El mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

Step-by-step explanation:

Una hogaza equivale a 12 torrejas de pan, si Mina tiene [tex]\frac{4}{5}[/tex] de la harina necesaria para preparar una hogaza. Entonces, el número total de torrejas es [tex]\frac{4}{5}[/tex] de 12 torrejas de pan. Es decir,

[tex]x = \frac{4}{5}\times 12[/tex]

[tex]x = 9.6[/tex]

Puesto que la cantidad de hogazas en un número entero, se trunca al entero más cercano. En consecuencia, el mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.

Set up the following ratio which applies to all angle bisectors  and the side opposite.

8 / (x + 4) = 12 / (2x + 1)                Cross multiply

8 * (2x + 1) = 12 * (x + 4)

16x + 8 = 12x + 48                        Subtract 8 from both sides

16x + 8 -8 = 12x + 48-8

16x = 12x + 40                              Subtract 12x from both sides

16x - 12x = 40

4x = 40                                         Divide by 4

4x/4 = 40/4

x = 10

16h 45min - 16h 35min= 10min

So, the answer is yes, she does and she still has 10 minutes free.

Yes she dose 1430+105+20=1555 hence there she made it to the bus stop on time.
