If BY = 6, YC = 10, AX = 18, then XC = <br> a: 10.8 <br> b:5 <br> c:30 <br> d:48
vampirchik [111]
To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,

    BY/YC = AX/XC

Substituting the known values,

    6/10 = 18/XC

The value of XC from the equation is 30. The answer is letter C.

Solve the equation: -8(2a-1)=36
SashulF [63]

The solution to the given equation is \frac{-7}{4}.

<h3>What is an expression?</h3>

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An expression is a combination of numbers, variables, or a combination of numbers and variables, and symbols and it is connected by the sign of equal.

We have,

Expression -8(2a - 1) = 36

So,

Now,

To get the solution to this expression,

i.e.

-8(2a - 1) = 36

Rewrite it as,

i.e.

Opening Brackets,

We get,

-16a + 8 = 36

Now,

Taking variable terms on one side and other terms on another side,

We get,

-16a = 36 - 8

On solving we get,

-16a = 28

i.e.

a = \frac{-28}{16} = \frac{-7}{4}

So,

The solution to the given equation is \frac{-7}{4}.

Hence, we can say that the solution to the given equation is \frac{-7}{4}.

Hector and Evelyn are solving the following problem. Find x,y, and z in this 45-45-90 triangle.
Murljashka [212]

Answer: A. They are both incorrect

Step-by-step explanation:

x=3√2

y=6

z=3√2

-----------------------

45-45-90=1:1:√2

------------------------

solve for x

x is the side accordingly to 90 in the smaller triangle, so it should be the [45] side times √2

3×√2=3√2

-----------------------

solve for y

y is the side accordingly to 90, so it should be the [45] side times √2

3√2×√2=6

----------------------

solve for z

z is the side accordingly to 45 in the bigger triangle, x is also accordingly to 45 in the bigger triangle

z=x

z=3√2
