Answer: x = 11, y = 9

Step-by-step explanation:

To solve for x, set the sides equal to each other:

7x + 27 = 10x - 6

Add 6 to both sides:

7x + 33 = 10x

Subtract 7x from both sides:

33 = 3x

Divide both sides by 3:

11 = x

(Which is the same as x = 11)

Now, to solve for y, since they don’t give you the other side, you know that the straight line is 180° so:

7x + 27 + 9y - 5 = 180

Plug in your x:

7(11) + 27 + 9y - 5 = 180

77 + 27 + 9y - 5 = 180

Add like terms:

99 + 9y = 180

Subtract 99 from both sides:

9y = 81

Divide both sides by 9:

y = 9

Answer:

$\frac{713}{44} = 16 \frac{9}{44}$

Step-by-step explanation:

7 3/4+ (12 - 3 6/11)

31/4 + (12 - 3 6/11)

31/4 + (12 - 39/11)

31/4 + 93/11

= 713/44 = 16 9/44

Quadrilateral QRST is a square. If the measure of angle RQT is 3x - 6. Find the value of x.

trapecia [35]

Given that quadrilateral QRST is a square.

Each angle of a square is of 90 degrees.

Angle <RQT is also an angle of 90 degrees.

We also given angle RQT = 3x - 6.

So, we can setup an equation as 3x-6 =90.

Now, we need to solve the equation for x.

6 is being subtracted from left side.

We always apply reverse operation. Reverse operation of subtraction is addition.

So, adding 6 on both sides of the equation, we get

3x-6+6 =90+6.

3x = 96.

3 is being multipied with x, in order to remove that 3, we need to apply reverse operation of multiplication.

So, dividing both sides by 3.

$\frac{3x}{3} = \frac{96}{3}$

x=32 (final answer).

3) Mathematical expression would be:
412 - 65 + 0.50x
Where, x = Number of Texts sent

4) Product means result after multiplication, sum after addition, quotient is the result of division with remainder, and difference is how far two numbers are in their magnitude.
"Per" tells us the magnitude for an Unit value.

5) Associative property = (a+b) + c = a+ (b+c)
Commutative property = a + b = b + a
Distributive Property = a(b+c) = ab+bc

They all have their unique characteristics and can be differentiated on that basis.

6) They all are same.
At the end, without parentheses and in proper symbol, it would be equal to -3/4

Hope this helps!

Answer:

the answers are a and d

Step-by-step explanation:

x+x+x=3x and you can't add a constant (2) to a variable(3x) so it would just be 3x+2
