What is the value of x?

Enter your answer in the box.

x =

The sum of angles in a triangle is always equal to  180 degrees

Add:

65 + 51 + x + 73 = 180

x + 189 = 180

x = -9      That is fine that x is "-9" because this would just mean that the angle "x+73" is just bigger than it is supposed to be.

Proof:

65 + 51 - 9 + 73 = 180

Therefore, x = -9

Answer:

x = -9

Step-by-step explanation:

Notes to remember:

A triangle's angles will always add up to 180°

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

As the image shows, we have two labeled angles. A 51° angle and a 65° angle.

Here's how you want to set up your equation:

180° = 51 + 65 + x + 73

(Rearrange)

180° = 51 + 65 + 73 + x

Add 51, 65, and 73

180° = 189 + x

Subtract 189 from both sides, to isolate x.

-9° = x

ALWAYS PLUG IN (the number that comes from the variable) TO CHECK YOUR WORK!

180° = 51 + 65 - 9 + 73

Data Set 1

Data Set 2

Answer:

First one is 20

Second one is 25

Step-by-step explanation:

Range equals largest number subtracted by smallest number

40 - 20 = 20

60 - 35 = 25

Answer:

A

Step-by-step explanation:

8x+4y-2x+6y-3

combining like terms would give us

6x+10y-3

would is A

Hey there!

8x + 4y - 2x + 6y - 3
COMBINE the LIKE TERMS

= (8x - 2x) + (4y + 6y) - (3)

= 8x - 2x + 4y + 6y - 3

= 6x + 10y - 3

Therefore, your answer is:

6x + 10y - 3 (Optipn A.)

Good luck on your assignment & enjoy your day!

Answer:

your answer might be 423/500

Step-by-step explanation:

0.846/1

0.846/1 x 1000/1000 = 846/1000

Answer:

423 /500=0.846

Step-by-step explanation:

Convert decimal to fraction

0.846 = 846/1000

Answer:

To factor out -1/3 out of the expression -1/3x - 8, first divide -8 by -1/3 to get 24. Now just put 24 in the place of -8 in the original expression. Your final answer should be -1/3(x + 24). Hope this helps and have a phenomenal day!

Step-by-step explanation:

Answer:

1/3(x-7)

Step-by-step explanation:

If you divide both the x value (1/3) and the constant value (7/3) by 1/3, you will get 1/3(x-7).

100

Step-by-step explanation:

428/4=107

107-7=100

Answer: You have to type the expression like "428 / 4 - 7"

Step-by-step explanation:

the "/" is the division symbol in this expression

Answer:

5 + -2= 3

Step-by-step explanation:

the answer is 3 because you have to make zero pairs. the 2 negatives and 2 of the positives make a zero pair, which makes 3 positive ones left so the final answer is 3

Answer:

6 miles

Step-by-step explanation:

A mile is 1760 yards; and hour is 3600 (=2x1800) seconds.

So a yard per second is roughly two miles per hour (actually 1800/1760 x2 miles per hour, so the error is about 40 in 1800 or less than 1 in 40, 2.5%) and three yards per second is about 6 miles per hour. Upper bound of the estimate would be 6 + 2.5% = 6+0.15 = 6.15 mph.

The probability of it happening is a 66.667%

100/10=10

ten is what they have in common

what you do to the bottom you have to do to the top

2x10=20

10x10=100 so 20/100 is equivalent to 2/10

Answer:

35.375

Step-by-step explanation:​​

Add −1.5 and 9.5 to get 8.

Multiply 0.4 and 18 to get 7.2.

Expand  −0.2/7.2 ≈−36 by multiplying both numerator and the denominator by 10.

Divide 72 by −2 to get −36.

Convert 36 to fraction 8/288=36.

Subtract 288 from 5 to get −283.

-283/8 =35.375

Answer:

For a stack of 12 DVD cases, it will be 132mm in height

Step-by-step explanation:

There are 7 cases stacked on top of each other and the total height is 77mm.

Since you must find the height of each individual DVD case you have to divide the height (77mm) by the number of DVD cases (7):

77 / 7 = 11        or       77 ÷ 7 = 11

Then, it asks to find the height of a stack of 12 cases, so take the 11, the height of each DVD case, and multiply it by 12:

11 × 12 = 132

So, the height of 12 DVD cases stacked on top of each other is 132mm.

Step-by-step explanation:

first derive a formula from that expression

y=kx

in this case k its a constant so we will find a constant first in order to derive a formula

substitute the variables with numbers been given

5=k(8) then make k subject of the formula

k=58 then make a formula from the constant

y= 58x

now this is your direct linear equation y= 58x

then use that equation in order to find the x value

finding x value, substitute the formula with the value given in this case y=15

then

y= 58x

15= 0.625x

150.625=x

24=x

therefore x =24

Answer: Antonio and Josue have 40 tickets left

Step-by-step explanation:

2 x ( 3 x 15 ) + ( 2 x 10 )

3 x 15 = 45

2 x 10 = 20

2 x 45 = 90

90 + 20 = 110

150 tickets is what they started with and they used 110 tickets 150 - 110 equals 40

It should be 110

2 x ( 3 x 15 ) + ( 2 x 10 )

3 x 15 = 45

2 x 10 = 20

2 x 45 = 90

90 + 20 = 110

110 = 40
