A. 6x + 10y - 3
B. 6x + 2y - 3
C. 10x + 2y - 3
D. 10x + 10y - 3

Answers

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.)

Solve for X please show work and or formula

Answers

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

I hope this helped!

The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of 7 cases and its height are shown. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of 12 cases.

Answers

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.

If the radius is 43, find
the diameter.

Answers

diameter = 2 × radius

radius= 43 CM

diameter= 2× 43 CM

diameter= 86 CM

Answer:

Diameter = 86 units

Step-by-step explanation:

What is radius and diameter?

The radius of a circle is a straight line from the middle of a circle to its perimeter. The diameter of a circle is a straight line that touches the perimeter of the circle, then intersects with the center of the circle, and touches the perimeter of the circle again.

How do we find the diameter?

The diameter of a circle is twice the radius, so 2 × 43 = 86 units

0.4 x 3.5 = 0.5 x ___?
Fill in the blank

Answers

Answer:

2.8

Step-by-step explanation:

Do 0.4 x 3.5 first, that gives you 1.4, then divide that by 0.5, which is 2.8.

If 0.4 times 3.5 equals 1.4 (0.4 x 3.5 = 1.4)
Then 1.4 divided by 0.5 equals 2.8 (1.4 divided by 0.5 = 2.8)
Then the missing number in the sentence is 2.8 (0.4 x 3.5 = 0.5 x 2.8)

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run? Explain

Answers

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.

You are investigating a murder involving poison. The victim was poisoned with a compound called di-chloro benzene whose formula is C6H4Cl2. Autopsy results show that the victims body contained about 31 g of the poison, but the actual amount could have been slightly higher due to tissue absorption. The main suspect is his wife, Suzanne, who works as a chemistry professor at the local university. Records show that she purchased 15 g of benzene (C6H6) two days before the murder. Benzene is one of the compounds used to make the poison, but she claims she was using it to make ethyl benzene (C6H5CH3), an innocuous compound, for use in her lab. She shows you the bottle of ethyl benzene she claims to have made. It contains 25 grams of ethyl benzene.Is she telling the truth or did she have more nefarious motives? If you can show that it is possible to produce 25 g of ethyl benzene from 15 grams of benzene, then she was telling the truth. Otherwise, you will have caught her in a lie, which makes it likely she killed her husband with the poison.
