Answer:

w+1     w≠-1

Step-by-step explanation:

(w+1)(w+1)

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

w+1

Cancel like terms

w+1     w≠-1

Answer:

w+1

Step-by-step explanation:

when you have a fraction that is composed of multiplied factors you can cancel out the numerator and denominator if they are equal to simplify it. in this cause (w+1) is seen on the top and bottom meaning you can cancel one of them out from the top by cancelling the one on the bottom out.

Answer:

[tex]p\geq 1.15(4,500)[/tex]

Step-by-step explanation:

If she makes a minimum profit, we need to use the symbol [tex]\geq[/tex], which indicates minimum quality.

Let's call [tex]p[/tex] profit, so the inequality which represent this problem would be

[tex]p\geq 1.15(4,500)[/tex]

The price of the car is multiplied by 1.15, because she must add her profit comission which is 0.15 or 15%.

Therefore, the right answer is the last choice.

Answer:

-2[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Answer:

-8/3 or -2 2/3

Step-by-step explanation:

-5 1/3 + 2 2/3 can be made into the improper fractions -16/3 + 8/3 if you multiply the whole number and the denominator together then add the numerator, so now you do the math:

-16 + 8 = -8

3 stays as the denominator leaving you with -8/3, or -2 2/3

Answer:

Step-by-step explanation:

The square root of a positive number cannot be negative.   False.  There are two square roots, one positive and one negative.

All positive numbers have two square roots.   True.  See above.

0 18 = 9 because 9(2) = 18.     Unable to answer; "0 81" is invalid.  Note that

√81 = ±9

49 = 7 because 7(7) = 49.  Invalid statement.  49 never equals 7.  Perhaps you meant √49 = ±7

25 = 5 because 52= 25.  Invalid statement.  Perhaps you meant √25 = ±5.

Please, before you do any more square root problems, learn how to type the  " √ " symbol or equivalent, such as "sqrt( "

Answer: 96

Multiply

3×6×7=126

2.5×4=10

(3)(-10)

Subtract

126-30=96

Answer:

96.

Step-by-step explanation:

Using order of operations:-  we deal with the parentheses first:

3 * (6 * 7 - 2.5 * 4)  Multiplying before the subtract in the parentheses:

= 3 * (42 - 10)       Now do the subtraction in the parentheses:

= 3 * 32

= 96.

Answer:

x = 2

Step-by-step explanation:

-5(x + 2) = -20

-5x - 10 = -20

-5x = -20 + 10

-5x = -10

x = -10/-5

x = 2

Answer:

Step-by-step explanation:

-5(x+2)=-20

-5x -10=-20

-5x=-10

x=2

Answer:

The area of the wall on the blueprint is 0.1764 ft²

Step-by-step explanation:

The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.

The scale factor is the ratio of the dimensions in two similar figures. The term "similar figures" refers to figures that have the same shape but different sizes.

 The ratio between areas is equal to the squared scale factor. This is,  the scale factor for areas is the squared scale factor,

To solve scale problems in this case, then the following proportion must be proposed:

[tex]\frac{representation area}{actual area} =scale factor^{2}[/tex]

Being:

Replacing:

[tex]\frac{representation area}{36 ft^{2} } =0.07^{2}[/tex]

Solving:

representation area= 0.07²*36 ft²

representation area=0.1764 ft²

The area of the wall on the blueprint is 0.1764 ft²

Answer:

Human activities such as driving cars, and working at factories contribute to global warming significantly because burning fossil fuels in cars releases carbon dioxide, which is the largest source of greenhouse gas emissions in the U.S. and as these gases build up, they trap heat in the atmosphere, causing climate change.

Answer: $35.91

Step-by-step explanation:

Since the jacket is 40% off, we multiply the original price by 60% to get the price remaining. ($57 x 0.6 = $34.20)

Then, we multiply the new price by 105% (includes the 5% sales tax) to get the total price. ($34.20 x 1.05 = $35.91)

Answer:

(3,2)

Step-by-step explanation:

Here's your given:

y = 4x - 10

y = 2

Because they both equal y, that means they equal each other:

2 = 4x - 10

Add 10 on both sides:

12 = 4x

Then, divide 4 on both sides:

3 = x

This represents the x coordinate.

Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:

y = 2

This represents the y coordinate.

Put the two values together to get: (3,2)

Answer:

Step-by-step explanation:

If you want the slope, then the formula is change y / change x.

-6 - -2 = -4

6 - -6 = 12

-4/12

-1/3

Hi there!

[tex]x + 50.75\geq \frac{387}{4} \\\\x\geq \frac{387}{4} -50.75\\subtract \\x\geq \frac{387}{4} - \frac{203}{4} \\solution:\\x\geq 46\\\\\\[/tex]

The answer is: C

Answer:

Yes your answer is c

Step-by-step explanation:

First convert to mixed fraction.

X + 50.75 > 387 / 4

Then subtract 50.75 from both sides

X + 50.75 - 50.75 > 387 / 4 - 50.75

Finally simplify,

X > 46

Answer:

You have three card : 3, 4, 5 and 6.

You first pick one card randomly, the probability of picking a 3 is:

P = 1/4

You then pick a second card without putting the first card back, the probability of picking a 3 is:

P = 1/3

=> The probability of picking a 3 and then picking a 3:

P = (1/4) x (1/3) = 1/12

Hope this helps!
