5 = -2 (x –  1)  (remove the parantheses)

5 = -2x + 2 (move the terms)

2x = 2 - 5 (calculate)

2x = -3 (divide both sides)

x= -3/2

5= -2x + 2 (move the terms)

2x = 2 - 5 (calculate)

2x = -3 (divide both sides)

x= -3/2

Answer: x=4 and y=7

Step-by-step explanation: x+3y=25

x+3y+−3y=25+−3y(Add -3y to both sides)

x=−3y+25

The answer is C.

The question is asking you to find an option that "supports" or "refutes" her claim. In option C, you have to hold the fabrics above a candle to see how long it will take to burn. This way of proving her hypothesis can either go good or bad (support that Fabric A resists better or refute her claim and Fabric B resists fire better).

Best of Luck!

Answer:

A scientist claims that Fabric A is better able to resist fire than Fabric B.

option describes an experiment that will produce evidence that will support or refute her claim is:

C. Hold each type of fabric over a candle flame and time w long it.

1. Positional Notation

2. Doubiling

3. An Online Converter

Step-by-step explanation:

Hey there!!!

We generally multiply using base 2 and keep power that starts from 0 and goes on increasing and add all them at last to convert binary to decimal.

For example:

011110

To convert into decimal follow the steps.

1st step: Multiply with base 2 and keep power from right side starting from 0.

[tex]0 \times {2}^{5} + 1 \times {2}^{4} + 1 \times {2}^{3} + 1 \times {2}^{2} + 1 \times {2}^{1} + 0 \times {2}^{0} [/tex]

2nd step: solve powers and multiply with binary numbers.

This implies;

= 0 + 16 + 8 + 4 + 2 +0

= 30.... is your answer.

Hope it helps....

Answer:

I think B option is correct ..I m 95% sure

Answer:i

the correct option is A

First we have to convert the 3 whole 8 /33 into a fraction so the method to do that is 33*3 =99 and then 99 +8 = 107 .The denominator will remain the same so we get 107 /33.Now by dividing 107 by 33 we get 3.242424

Answer:

The correct option is;

1

Step-by-step explanation:

A line in geometry is an array of points that lay on the path of a ray and extends along the ray path in both directions infinitely, while a point in geometry marks a location

Therefore, given that the points A and B are on the same line, and are therefore on the same ray that gives the direction of the line, the number of distinct lines that can contain the both A and B, given that the original line extends to infinity in both direction is 1.

Answer:

a² + b² = 68

a3 + b3 = 520

Step-by-step explanation:

Given :

a + b = 10 (1)

ab = 16 (2)

A. Find a² + b²

(a + b)² = a² + 2ab + b² (3)

Substitutite the values of (1) and (2) into (3)

(10)² = a² + 2(16) + b²

100 = a² + 32 + b²

Subtract 32 from both sides

100 - 32 = a² + b²

a² + b² = 68

B. a^3 + b^3

(a + b)^3 = a^3 + b^3 + 3ab(a + b)

(10)^3 = a^3 + b^3 + 3*16(10)

1000 = a^3 + b^3 + 480

a^3 + b^3 = 1000 - 480

a3 + b3 = 520

Answer:

Formula: n+6

In mathematics, a recursive definition is used to define the elements in a set in terms of other elements in the set. 

Answer:

TU = 5

Step-by-step explanation:

Since, U is the midpoint of TV.

[tex]\therefore TV = 2 \times TU \\ 3x - 23 = 2(x - 6) \\ 3x - 23 = 2x - 12 \\ 3x - 2x = 23 - 12 \\ x = 11 \\ \\ TU = x - 6 \\ TU = 11 - 6 \\ \huge \red { \boxed{TU = 5}}[/tex]

Answer:

(n)*(x+y)(x-y)

Step-by-step explanation:

First of all, you take the n out, and then you use the formula of x²- y² and it will equal to (x+y)(x-y).

Answer:

n(x+y)(x−y)

Step-by-step explanation:

1. To factor this equation, first, you can see that both the x^2 and the y^2 have an n next to them.  So, you can take out the n.  You get this: n(x^2-y^2)

2. After you take the n out, you can also factor the (x^2-y^2) since they are both squared (to the second power).  To do this, you simply split the two apart and make sure to include the negative.  You get this, the final answer:

n(x+y)(x-y)

3. You can check it by multiplying out the answer, and once multiplied out, you get the original expression of x^2n-y^2n.

Answer:

102.66666667 feet/ seconds

Step-by-step explanation:

From the question, we are told to convert 70 miles per hour to feet per second.

Step 1

1 mile = 5280 feet

70 miles = x feet

Cross Multiply

1 mile × x feet = 5280 feet × 70 miles

x feet = 5280 feet × 70 miles

x feet = 369600 feet

Hence, 70 miles = 369600 feet

Step 2

We convert 369600 feet/ hour to feet per second

60 seconds = 1 minute

60 minutes = 1 hour

1 hour = 60 × 60

= 3600 seconds.

369600 feet/ 1 hour = 369600 feet/3600 seconds

= 102.66666667 feet/ seconds

Therefore, 70 miles per hour is equivalent to 102.66666667 feet/ seconds

-1.98, -0.9, -1 [tex]\frac{8}{9}[/tex], -1.68

Step-by-step explanation:

In the case of negative numbers the "larger" the number is, the least it is. For the fraction I just tossed 8/9 into my calculator to get the decimal version that way I could put it in order accuratly.

Answer:

96

Step-by-step explanation:

multiply by 12 because thats how many inches are in a foot

There are 96 inches in 8 feet.

There are 60 inches in 5 feet. Therefore,

5 feet = 60 inches

8 feet = ?

cross multiply

length in inches = 60 × 8 / 5

length in inches = 480 / 5

length in inches = 96 inches.

Therefore, there are 96 inches in 8 feet.
