Please Help Me Solve These Algebraic Expressions And Turn Them Into Simplified Fraction(They Are Two

Answers

Answer 1

Answer:

h) (3 - 2b)/4b²

k) (2b - 3a)/ab³

Step-by-step explanation:

h) 3/4b² - 1/2b

multiply 1/2b, both top and bottom, by 2b, so 1/2b = 2b/4b²:

3/4b² - 2b/4b² = (3 - 2b)/4b²

k) 2/ab² - 3/b³

multiply 2/ab², both top and bottom, by b, so 2/ab² = 2b/ab³:

multiply 3/b³, both top and bottom, by a, so 3/b³ = 3a/ab³:

2b/ab³ - 3a/ab³ = (2b - 3a)/ab³

Answer:

  (d)  b/a

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

__

Then the expression simplifies to ...

  b^-2/(ab^-3) = b^(-2-(-3))/a = b^1/a = b/a

According to the diagram below, which similarity statements are true?
Check all that apply.
P

B. APQR ~ APSQ
O C. APQR ~ AQSR
D. APQS ~ AQRS

Answers

The required triangle PQS and triangle QRS are similar triangles. Option D is correct.

What are Similar triangles?

Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.


According to the diagram,
It can be inferred that triangle PQS and triangle QRS are similar to each other. The term "similar" implies that these two triangles have the same shape but can be different in size. Specifically, the corresponding angles of these triangles are equal, and the corresponding sides are in proportion.

Consider triangle, PQS, and triangle QRS

Angle S is the common angle in both the triangles
And angle Q is similar to angle R

So both the triangle are similar by AA similarity postulate

Therefore, option D is correct.

plz help find perimeter and area

Answers

so I’m not sure what area is because I struggle with it too.
But perimeter is like adding all the sides together
so: 5x+2+X+8+5x+2+X+8
You collect all the terms which is 5x and X then that gives u 12x+2+8+2+8
Keep the 12x But add all the other numbers
so ur answer for perimeter would be
(12x+20)

I hope this helps for perimeter ❣️

What is the sum of the difference?

Answers

Answer:

A. 9x^4 and 3x^5y

Step-by-step explanation:

there are two ways to solve this:

first way:

You can solve this my substituting numbers for x and y in this case i used 2 for x and 3 for y and see which one is equal to the original equations

the second way is the regular way

when you add or subtract numbers with variables and exponents you want to add the constants and add the exponents in this case [tex]5x^{4} +4x^2[/tex] is the same as [tex](5x+4x)^(4+4)[/tex] = [tex]9x^4[/tex]and you can do the same process for subtraction

[tex]12x^{5}y-9x^5 y\\(12x-9x)^(5+5)*y[/tex]= [tex]3x^5y[/tex]

Answers

Answer:

96

Step-by-step explanation:

1 pound is 16 ounces

6 pounds=x ounces

So we use the X to signal it's presence

1x16 is 16,

That means 16 ounces

6xP=Q

6x16 will give us our answer

Because it will tell us how many pounds there are since ounces is multiplied to get ounces.

6x16=96

P=16

Q=96

96 is our answer.

What is the slope of a line perpendicular to the line of the equation in the above ? Please help answer !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

- 4

Step-by-step explanation:

Slopes of perpendicular lines are negative-reciprocals.If m is the slope of one line, the slope of the perpendicular line is -1/m.

Let's find the slope of the given line:

x - 4y = -12

Rewrite this in the slope-intercept form: y = mx + b

x - 4y = -124y = x + 12y = 1/4x + 3

The slope is 1/4

The perpendicular line has slope

- 1/(1/4) = - 4

14. A system of equations is shown below. For what value of a will this system have no solutions? Justify your answer.
y = 4x-9
y = ax+6​

Answers

Answer:

a = 4

Step-by-step explanation:

a = 4

If a = 4, then both lines have the same slope and different y-intercepts. That makes both lines parallel. Since the lines never intersect, there is no solution.

Answer:

x can not equal zero, as it would cause division by zero.

Step-by-step explanation:

First, let's make one equation out of them and see what we get.  Because both of them have y on the left, we can say that the two right sides are equal, giving us:

4x - 9 = ax + 6

If we solve for a, we get:

ax + 6 = 4x - 9

ax = 4x - 15

a = 4 - 15 / x

With that arrangement we can see clearly that x can not be equal to zero, as it would give us division by zero.

Mary has a budget for groceries fuel, and utilities. She spent 30% of her budget in groceries if mary spent 42$ on groceries than how much is her budget

Answers

Given:

Mary spent 30% of her budget in groceries.

She spent 42$ on groceries.

To find:

The total amount of her budget.

Solution:

Let x be the total amount of the budget.

Then, the amount spent on groceries is 30% of x.

[tex]\dfrac{30}{100}x=0.3x[/tex]

She spent 42$ on groceries.

[tex]0.3x=42[/tex]

Divide both sides by 0.3.

[tex]x=\dfrac{42}{0.3}[/tex]

[tex]x=140[/tex]

Therefore, the total amount of the budget is 140$.

The selling price of an item is ​$585. It is marked down by ​%20, but this sale price is still marked up from the cost of ​$360. Find the markup from cost to sale price.

Answers

Answer:

$108

Step-by-step explanation:

The selling price being marked down by 20% means that $585 was reduced by 20%

Selling price = $585 - ( 20% x $585)

$585 - (0.2 x $585) = $468

Markup from cost = selling price - cost price

$468 - $360 = $108
