The value of y will be equal to 4.61.

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.

The value of y will be calculated by using the Pythagorean theorem:-

a² + a² = (9√2)²

a = 9

Applying angle property in the triangle:-

$tan26 = \dfrac{MK}{9}$

9tan26 = MK

LM = 9 - 9tan26

LM = 9 - 4.38

LM = 4.62

Therefore the value of y will be equal to 4.61.

A+ 2b = 10 2a + b =6

GenaCL600 [577]

First you can solve for b: Subtract a on both sides and get 2b=-a+10, then divide by 2 to get b by itself and get: b=-1/2a+5

Then you can plug in this equation for b in the other: This would give you: 2a+-1/2a+5=6. Then you can use that equation to solve for a and get: 1.5a+5=6, subtract 5, 1.5a=1, divide by 1.5, a=1/1.5

Then you can plug in the value of a to solve for b.

Elimination <br> 2x - 5y = 8 <br> x - 3y = -1

ruslelena [56]

X=29 and y=10

You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.

How do you create your equations when working on a mixture word problem?

Let's try to think about the general form of a word problem involving mixtures.

In general, we have the following scenario:

a merchant sells two kinds of products (coffee, sweets, etc).

we know the unit prices for both kinds of products and for the final mixture

US dollars per pound for the first kind of product,

US dollars per pound for the second kind of product

US dollars per pound for the mixture

we know the total quantity formed by the mixture of the two products (

pounds)

we have to find out the quantities of each product needed to form the mixture

(here we have the variables:

denoting the quantity of the first kind of product and

denoting the quantity of the second kind of product)

Now, we have sufficient information to work out the equations.

First, we know that the sum of the two quantities is

pounds, which gives us the first equation:

Second, we know that the sale price is the product of quantity and unit price, which gives us the second equation:

⋅

Now, we have a system of two linear equations that can be easily solved by substitution.
