Step-by-step explanation:

Hey there!

Your required answer is option B.

Here,

Given,

The figure is an equilateral triangle with, side (7x+9) and (x+27).

By the defination of equilateral triangle we have,

All sides of equilateral triangle are equal. 

So,

$( 7x+ 9) = x + 27$

Simplify them to get answer.

$7x - x = 27 - 9$

$6x = 18$

$x = \frac{18}{6}$

Therefore the value of x is 3.

Hope it helps...

18% of what number is 7.2?

RUDIKE [14]

18% of 40 is 7.2

Change the percentage (18%) into a decimal by dividing it over 100:

18/100 = 0.18

Divide 7.2 by the decimal (0.18):

7.2 / 0.18 = 40

Which equation could be used to solve for the measure of side Q in the triangle QRS shown below given...

Rama09 [41]

The image is missing, so i have attached it

Answer:

Equation is;

q/sin 105 = 15/sin 30

Step-by-step explanation:

We are given;

Angle Q = 105°

Angle S = 30°

s = 15

From sine rule we know that;

a/sin A = b/sin B = c/sin C.

Thus, applying that to this question, we can find side q.

Thus;. q/Sin Q = s/Sin S

Plugging in the relevant values to obtain ;

q/sin 105 = 15/sin 30

17. Explain whether 11t - 4t is equivalent to 4t - 11t.

nydimaria [60]

Answer:

So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )

Step-by-step explanation:

Given:

$11t - 4t$ ..............Equation ( 1 )

$4t - 11t$ ................Equation ( 2 )

To Find:

Whether Equation ( 1 ) is Equivalent to Equation ( 2 )

Support your answer by evaluating the expression for t = 2.

Solution:

For t=2 Equation ( 1 ) we get

$11t - 4t=11(2) - 4(2)=22-8=14$

For t=2 Equation ( 2 ) we get

$4t - 11t=4(2) -11(2)=8-22=-14$

From above we get two different values

So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )

Matt has answered 20 over 25 of the questions on a test. what percentage of the test question has Matt answered

lyudmila [28]

So,

Matt answered 20 out of 25 questions.
$\frac{20}{25}$

We need to get the denominator to be 100. We can do that by multiplying the fraction by a form of 1.
$\frac{20}{25} * \frac{4}{4} = \frac{80}{100}$

From here, it should be easy to see that Matt has answered 80% of his test.
