What is the simplified expression for 5^-3 x 2^2 x 5^6 / 2^3 x 5^2 1) 2^2/5^2 2) 5/2^2 3) 5/2 4) 5^2/2

1) 2^2/5^2
2) 5/2^2
3) 5/2
4) 5^2/2

Answers

Answer 1

Its: 3) 5/2

Explanation:

too complicated

Answer 2
It’s 3) 5/3
Explanation:

5^-3 x 2^2 x 5^6
_____________

2^3 x 5^2

Now workout the numerator and the denominator.
Multiplication means add the indices.
Same denominators so add up the indices, 5^-3 x 5^6 –> -3 + 6 = 3

5^3 x 2^2
________

2^3 x 5^2

Divide means take the indices away.(Same base number only)
5^3 divided by 5^2 —> 3-2 = 1
5^1 = 5

2^2 divided by 2^3 —> 2-3 = -1
2^-1 = 1/2 or 0.5
Then the answer is 5/0.5 which is 2.5
And 5/2 is equal to 2.5 so it must be number 3

Match each rational number with a point on the number line.
(Be sure to use the numbers 1 through 4 to indicate which rational number goes in each answer box)

Answers

Answer:

The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Step-by-step explanation:

Consider the provided number line.

From the number line we can observed that:

1) A, B, C and D lies between -1 and 0.

2) Point A and B lies between -1 and -0.5

3) Point C and D lies between -0.5 and 0

Therefore, the value of A and B must have a negative value lying between -1 and -0.5

Also, the value of C and D must have a negative value lying between -0.5 and 0.

Now consider the provided options.

Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16

This is Incorrect representation because the value of A and B should lying between -1 and -0.5.

Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.

Also they are in ascending order from -1 to 0.

Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Directions: Match the slope and y-intercept values to the correct boxes below.

PLEASE HELP!!!!!!

Answers

Answer:

slope is -3

y-intercept is 3

Step-by-step explanation:

Answer:

y-intercept: 3

Slope: -3

Step-by-step explanation:

y-intercept

To find the y-intercept, see what point on the y-axis (vertical bold line on the graph) the line passes through.

Slope

To find slope, find 2 points (from left to right) on the line and and put the height difference over the width difference in a fraction (simplify if possible). At points (0,3) and (1,0) there is a height drop of 3 (so -3) and a width of 1 and [tex]\frac{-3}{1}[/tex] gives you a slope of -3.

2) Thomas wants to find the difference
1/2 (6x - 2) - (2x + 1)

He does the following:

1/2 (6x - 2) - (2x + 1)
3x - 1 - x + 1/2 =
3x + x - 1 + 1/2 =
4x - 1/2

Is this correct? If not, show the correct procedure and explain where Thomas made his mistake.​

Answers

He is not correct, his mistake was multiplying 1/2 to 2x and 1, when you should have multiplied the negative to them.

Answer:

Thomas is not correct, x-2 is the correct answer

Step-by-step explanation:

Thomas made his mistake by multiplying the 1/2 by both (6x-2) and -(2x+1). Thomas should have multiplied the 1/2 by just the (6x-2).

Correct procedure:

1/2 (6x-2)-(2x+1)

(3x-1)-(2x+1)

Step-by-step explanation:

6 4/5+ 5 1/2+ 3 7/10

make all fractions with common denominators

6 8/10 + 5 5/10 + 3 7/10

combine like terms

6+5+3= 14

8+5+7 = 20/10 = 2

14+2 = 16

Answer:

550 pieces of candy (total), 150 pieces of candy for Maria, 200 pieces of candy for Lucas, 200 pieces of candy for Mateo.

Step-by-step explanation:

Maria filled

6 + 4 + 5 = 15 boxes of candy.

Lucas filled

3 + 7 + 10 = 20 boxes of candy.

Mateo filled

3 + 7 + 10 = 20 boxes of candy.

x = 10 pieces of candy.

15x = 150 pieces of candy (Maria).

20x = 200 pieces of candy (Lucas).

20x = 200 pieces of candy (Mateo).

150 + 200 + 200 = 550 pieces of candy in total.

Ben and Arnoldo are sharing snacks. They have peanut treats and coconut treats. Ben ate 2 of the peanut treats and 4 of the coconut treats for a total of 160 calories. Arnoldo ate 3 of the peanut treats and 2 of the coconut treats for a total of 140 calories. They wrote the system below to represent the number of calories there are in the two types of treats.

2 x + 4 y = 160. 3 x + 2 y = 140.

They found the solution to be (30, 25). How many calories are in each treat?

Answers

Answer:

It means there are 30 calories in peanut treat and 25 calories in coconut treat.

Step-by-step explanation:

There are 30 calories in peanut treat and 25 calories in coconut treat.

Given: Ben ate 2 of the peanut treats and 4 of the coconut treats for a total of 160 calories.

The equation corresponding to the above statement is

Also, Arnoldo ate 3 of the peanut treats and 2 of the coconut treats for a total of 140 calories.

The equation corresponding to the above statement is

i.e. x represents the number of calories in one peanut treat and y represents the number of calories in one coconut treat.

Also, the solution of system of linear equations is in the form of (x,y).

The given solution : (30,25)

It means there are 30 calories in peanut treat and 25 calories in coconut treat.

24x - 17 x ≥ 13x +15

Pls solve and add the equation if you can thank you :)

Answers

Given :-

[tex]24x - 17 x ≥ 13x +15[/tex]

Solving it,

[tex](24 - 17)x \geqslant 13x + 15[/tex]

[tex] = > 7x \geqslant 13x + 15[/tex]

[tex] = > 7x - 13x \geqslant 15[/tex]

[tex] = > (7 - 13) x \geqslant 15[/tex]

[tex] = > - 6x \geqslant 15[/tex]

[tex] = > x \leqslant - \frac{15}{6}[/tex]

By reducing to lowest terms, we get,

[tex]x \leqslant - \frac{5}{2}[/tex]

So, Value of x is [tex] - \frac{5}{2}[/tex]

Simplifying
24x + -17x = 13x + -15

Combine like terms: 24x + -17x = 7x
7x = 13x + -15

Reorder the terms:
7x = -15 + 13x

Solving
7x = -15 + 13x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13x' to each side of the equation.
7x + -13x = -15 + 13x + -13x

Combine like terms: 7x + -13x = -6x
-6x = -15 + 13x + -13x

Combine like terms: 13x + -13x = 0
-6x = -15 + 0
-6x = -15

Divide each side by '-6'.
x = 2.5

Simplifying
x = 2.5

When you see a power raised to another power you should keep the base and multiply the exponents.
