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
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.

There are 42 more red marbles in a jar than there are white marbles. If there are 238 marbles in the jar, how many of them are red and how many are white?
Answers
Answer:
Red: 161 White: 77
Step-by-step explanation:
Given there are 238 marbles in a jar, and there are 42 more red marbles than white marbles, we need to divide the number of marbles by two, as there are, presumably, two colors.
238 / 2 = 119
After doing this, we subtract 42 from one of the two 119s, and we add 42 to the other.
119 - 42 = 77
119 + 42 = 161
The value with 42 added is the red marble count, and the value with 42 subtracted is the white marble count.

The symbol _____________ means "is similar to" and the symbol ____________ is the abbreviation for the word angle.
Answers
Answer:The symbol \sim∼ means "is similar to" and the symbol \angle∠ is the abbreviation for the word
angle.
Step-by-step explanation: i hope it is right i am sure it is
The symbol "[tex]{\sim}[/tex]" is commonly used to represent the mathematical concept of "is similar to." while "∠" represents the concept of an angle.
The symbol "[tex]{\sim}[/tex]" is commonly used to represent the mathematical concept of "is similar to." often used in mathematical equations or geometric diagrams to indicate the presence of a similarity.
On the other hand, the symbol "∠" is the abbreviation for the word "angle." In geometry, an angle is formed when two rays or line segments share a common endpoint.
Thus, the symbol "[tex]{\sim}[/tex]" is commonly used to represent the mathematical concept of "is similar to." while "∠" represents the concept of an angle.

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.
