Answer: 456 chairs

Step-by-step explanation:

If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42

If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414

Then you add up all the chairs, 456 chairs total.

Of the following equations below, which equation represents a direct variation between x and y?
spin [16.1K]

Answer:

C. y +3 = x +3

Step-by-step explanation:

We need to find in below option x has direct variation with y.

We solve for each;

A. 2y = 3x-7

From above equation we can state that 2 times y is equal to 7 less than 3 times of x.

Hence it doesn't represent direct variation.  

B. y-4 = x+6

Solving above expression we get;

y-4 = x+6\\y = x+6+4\\y=x+10

From above equation we can state that y is equal to 10 more than x.

Hence it doesn't represent direct variation.

C. y+3 = x+3

Solving above expression we get;

y+3 = x+3\\y = x+3-3\\y=x

From above equation we can state that y is equal to x.

Hence it represent direct variation.

D. 4y+1 = 4x-1

Solving above expression we get;

4y+1 = 4x-1\\4y = 4x-1-1\\4y=4x-2

From above equation we can state that 4 times y is equal to 2 less than 4 times of x.

Hence it doesn't represent direct variation.

Hence the Answer which represent direct variation of x and y is,

C. y+3 = x+3

Help me i’m stressed
Aleks04 [339]

Answer:

<h3>m∠1 = 41°</h3><h3>m∠2 = 41°</h3>

Step-by-step explanation:

<h3>m∠1 = m∠2</h3>

{(6x + 11)}^{o}   =  {(10x - 9)}^{o}  \\ 11 + 9 = 10x - 6x \\ 20 = 4x \\  \frac{20}{4}  =  \frac{4x}{4}  \\ 5 = x \\

x = 5°,

m∠1 = (6x + 11)°

{(6x  + 11)}^{o}  \\ 6(5) + 11 \\ 30 + 11 \\  {41}^{o}  \\
