There are an infinite number of equivalent expressions. Perhaps the simplest is the value of the expression:

  4 - 4 = 0

Answer:

Step-by-step explanation:

4. (6^10)^-7 is when the exponents should be multiplied

   answer is B

5. (7^3)^-2 = (7^-6)

     1/7^6 = 1/(7x7x7x7x7x7)

answer is A

2. 11^-4/11^8= 1/11^(8+4) = 1/11^12

   answer is A

Answer:

3) Y = -1.5

Step-by-step explanation:

7=-2y+4

We move all terms to the left:

7-(-2y+4)=0

We get rid of parentheses

2y-4+7=0

We add all the numbers together, and all the variables

2y+3=0

We move all terms containing y to the left, all other terms to the right

2y=-3

y=-3/2

y=-1+1/2

Answer:

x = 12

Step-by-step explanation:

From the question given above, the following data were obtained:

m < EDG = 112°

m < EDH = 6x – 9

m < HDG = 4x + 1

x =.?

Thus, we can obtain the value of x as shown below:

m < EDG = m < EDH + m < HDG

112 = 6x – 9 + 4x + 1

112 = 6x + 4x – 9 + 1

112 = 10x – 8

Collect like terms

112 + 8 = 10x

120 = 10x

Divide both side by 10

x = 120/10

x = 12

Therefore, the value of x is 12.

Answer:

Infinite Solutions

Step-by-step explanation:

6x+6=6(x+1)

6x+6=6x+6

If both sides of the equations are equal, it will ALWAYS be infinite solutions:)

Answer:

Infinite solutions.

Step-by-step explanation:

You have to distribute the 6 to the x and the 1. You'll then realize that both sides have 6x+6, and since 6x-6x=0 and 6-6=0,  If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions.

Answer:

O.8 is greater than 7/10

Step-by-step explanation:

0.8 is in the tenths Place So you know that equals 80 ones Out of one hundred. So you have 80/100 if you divide 80 and 100 by ten it reduces to 8/10. You know that 8/10 is greater than 7/10. Hope this helped .

Answer: 60 feets

Step-by-step explanation:

Given the question :

Find the missing dimensions. Use the scale factor 1 inch:12 feet. A plastic toy bird has a wingspan of 5 inches. What is the actual bird wingspan?

Using a scale factor of 1 inch : 12 feet

Wingspan of plastic toy bird = 5 inches

Calculate the actual bird wingspan

(1 inch / 12 feet) = (toy bird wingspan / actual bird wingspan)

( 1 inch / 12 feet) = (5 / actual bird wingspan)

Actual bird wingspan = 5 × 12

Actual bird wingspan = 60 feets

Step-by-step explanation:

Answer:

  32.7 cm

Step-by-step explanation:

For central angle θ in radians, the arc length is given by ...

  s = rθ

The angle between 12 and 5 is 5π/6 radians, and the radius is 25/2 cm, so the arc length is ...

  s = (25/2 cm)(5π/6) = (125/12)π cm ≈ 32.7 cm

The arc length between the markings is about 32.7 cm.

Answer:

n = 10

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]

Given

([tex]y^{20}[/tex] ) ([tex](y^{-5}) ^{2}[/tex]

= [tex]y^{20}[/tex] × [tex]y^{-10}[/tex]

= [tex]y^{(20-10)}[/tex]

= [tex]y^{10}[/tex] → in the form [tex]y^{n}[/tex] with n = 10

10.

Answer:

x = 10 4/5

Step-by-step explanation:

We want to find the value of x in the expression below;

2 1/4/x = 1 1/2/3 3/5

The best thing to do here is to turn all the mixed fractions to improper fractions. Thus, we have;

9/2/x = 3/2/18/5

= 9/2x = 3/2 * 5/18

9/2x = 15/36

9 * 36 = 15 * 2x

324 = 30x

x = 324/30 = 10 8/10 = 10 4/5

Answer:

The correct answer is C or 0.5 or 1/2.
