Answer:

9/80

Step-by-step explanation:

1)\ x + \frac{9}{20} = \frac{9}{16}

2)\ x = \frac{9}{16} - \frac{9}{20}

3)\ x = \frac{9}{16} - \frac{9}{20}

4)\ x = \frac{45}{80} - \frac{36}{80}

5)\ x = \frac{9}{80}

3y= 21

I think 3y would be 21 because in the equation, 5y+13=48, y= 7. So if we know that y is 7 that’ll mean we’ll use 7 to interpret y for 3y.

Help asaaaap explain please!!!!!
mariarad [96]

Answer:

C

Step-by-step explanation:

Once

\sqrt{xy} = 6

We know that xy = 36

There are infinity values for x, y, but considering x, y \in \mathbb{Z}

Below we have all the solutions for x, y

Negative:

\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and }  y = -3\\x = -9 \text{ and }  y = -4\\x = -6 \text{ and }  y = -6\\x = -4 \text{ and }  y = -9\\x = -3 \text{ and }  y = -12\\x = -2 \text{ and }  y = -18\\x = -1 \text{ and }  y = -36\\

Positives:

x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and }  y = 3\\x = 9 \text{ and }  y = 4\\x = 6 \text{ and }  y = 6\\x = 4 \text{ and }  y = 9\\x = 3 \text{ and }  y = 12\\x = 2 \text{ and }  y = 18\\x = 1 \text{ and }  y = 36\\

We can see that x + y \neq 18

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).

What multiplies to be 42 and adds to be 23?
Furkat [3]
A) x * y = 42  (or x = 42/y)
B) x + y = 23

B) 42/y + y = 23
42 + y^2 = 23y
y^2 -23y + 42 = 0

The numbers are 21 and 2
