Answer:

10a-10ab-7b

Step-by-step explanation:

i dont feel like putting the steps but ik this is correct

The answer is -4a -8ab -7b after subtracting  8b - ab + 7a from 3a - 9ab + b.

It is defined as the combination of constants and variables with mathematical operators.

We have two expressions:

8b - ab + 7a and  3a - 9ab + b

After subtracting:

= (3a - 9ab + b) - (8b - ab + 7a)

= -4a -8ab -7b

Thus, the answer is -4a -8ab -7b after subtracting  8b - ab + 7a from 3a - 9ab + b.

Answer:

45

Step-by-step explanation:

Answer:

a = 45

b = 15

Step-by-step explanation:

From the information given, you can deduce that both ΔPQR and ΔPSR are isosceles triangles that share base PR. This means that ∠a = ∠SRP because the base angles of an isosceles triangle are always congruent.

Because the vertex of ΔPSR is 90°, you know that the base angles add up to 90 because 180(sum of a triangle's angles) - 90 = 90. 90/2 = 45, so a = 45.

To find b, you need to subtract the base angle of ΔPSR from the base angle of ΔPQR. ΔPQR's base angle is 60, because 180 - 60 = 120 and 120/2 = 60. 60 - 45 = 15, so b = 15.

========================================================

Explanation:

Rule: The interior (inside) angles of a triangle always add to 180

K+L+M = 180

5x+9x+4x = 180

18x = 180

x = 180/18 ... divide both sides by 18

x = 10

That x value directly leads to...

As a check,

K+L+M = 50+90+40 = 180

This confirms we have the right x value.

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

We can further say,

note how interior angles K and L add to exterior angle LMN

50+90 = 140

This is an application of the remote interior angle theorem.

Answer:

Angle K = 50

Angle L = 90

Angle KML = 40

Angle LMN = 140

Step-by-step explanation:

Solve for x. We know that triangles' interior angles add up to 180.

So, we can set the values to equal to 180 and solve for x.

5x + 9x + 4x = 180

Simplify.

18x = 180

Now, divide by 18.

x = 10

Now, plug 10 in for each angle.

Angle K = (5 * 10) = 50

Angle L = (9 * 10) = 90

Angle KML = (4 * 10) = 40

For this last angle, we use the supplementary theorem that says "angles that are supplementary to each other add up to 180".

So, we do angle LMN + 40 = 180

Angle LMN = (180 - 40) = 140

Complete Question

A certain 50 cm spring will stretch (in  cm) one fifth  the weight (in kg) attached to  it. How long will the spring be if a 35  kg weight is attached to it

Answer:

The value is [tex]L_w = 57 \ cm[/tex]  

Step-by-step explanation:

The length of the spring is [tex]L = 50 \ cm = 0.5 \ m[/tex]

 The  mass attached to it is  [tex]w = 35 \ kg[/tex]

Generally given from that the spring will stretch one fifth of the weight  (in kg)attached to it , it then means that the  new length of the spring whenever a weight is attached to it is mathematically represented as

          [tex]L_w = L + \frac{W}{5}[/tex]

=>      [tex]L_w = 50 + \frac{35}{5}[/tex]  

=>      [tex]L_w = 57 \ cm[/tex]  

Answer:

x = 1/9

Step-by-step explanation:

we want to solve the proportion;

we simply cross multiply the values

Mathematically, that will be calculated as follows;

6x * 21 = 2 * 7

6x * 21 = 14

6x = 14/21

2(3x) = 2(7/21)

3x = 7/21

3x = 1/3

x = 1/3/3

x = 1/9

Answer:

Step-by-step explanation:

The x-terms are the same in each equation, so subtracting one equation from the other will eliminate the x-variable.

The y-terms are opposites in the two equations, so adding the two equations will eliminate the y-variable.

Both strategies (subtracting, adding) are applicable to this system of equations.

Answer: 16 units

Step-by-step explanation: adding the perimeter sides to get the perimeter of triangle ABC would be 4.1+6.1+5.8 = 16

Answer:

16

Step-by-step explanation:

AC = 6.1

CB = 5.8

BA = 4.1

Use whole number approximations for the three side lengths.

AC = 6

CB = 6

BA = 4

perimeter = AC + CB + BA = 6 + 6 + 4 = 16

Step-by-step explanation:

As we can see the more people who rent out a lane, there are more people bowling.

The statement is best supported by the scatterplot is D. There is a positive linear association between the number of lanes rented and the number of people who bowl.

Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing.

Given that daily attendance at a bowling alley was recorded for 15 days.

The scatterplot represents the number of lanes rented each day and the number of people who bowled that day.  

By looking at the scatter plot graph we will have that there is a positive linear association between the number of lanes rented and the number of people who bowl.

The statement is best supported by the scatterplot is D. There is a positive linear association between the number of lanes rented and the number of people who bowl.

Explanation:

Check out the image below. I've posted the synthetic division table. The value at the very end of the bottom row is the remainder. By the remainder theorem, this is exactly the value of g(-5).

Recall the remainder theorem says: If you divide p(x) by (x-k), then the remainder is p(k). In this case, k = -5 is our test root which is the value placed in the box on the left.

As a way to check the answer, we can say

g(x) = 2x^2 + 6x + 5

g(-5) = 2(-5)^2 + 6(-5) + 5

g(-5) = 25

So the answer is confirmed.

Step-by-step explanation:

Regina originally packed 10 goodies bags for her birthday party. She found out the day before the party that a few more friends would be attending so she made three additional bags for the party. Write an algebraic expression to represent the total number of candies and toys that Regina made for her birthday party.

Let the number of candies = c

Let the number of toys = t

The total number of goodies bags she made = 10 + 3 = 13 goodie bags

Hence,

The total number of candies and toys that Regina made for her birthday party

c + t = 13

Answer:

f^(-1)(x) = 4x + 48.

Step-by-step explanation:

Is suppose the function is f(x) = 1/4 x - 12

This is equivalent to the line y = 1/4 x - 12.

To get the inverse, change the x and y:

x = 1/4 y - 12

Now solve for y:

x + 12 = 1/4 y

y = 4x + 48

So the inverse f^(-1)(x) = 4x + 48.

Answer:

f-1(x) = 4x + 48.

Step-by-step explanation:

let f(x) = y = 1/4 x - 12

We solve for x:

y = 1/4 x - 12

1/4 x = y +12

Multiply through by 4:

x = 4y + 48

The inverse  f-1(x) = 4x + 48.

Answer:

Step-by-step explanation:

Since CE is perpendicular to AD , then ∠ AEC = 90° and

∠ BEC = 90° - 65° = 25° , then

∠ BED = ∠ BEC + ∠ DEC = 25° + 90° = 115°

Answer:

Step-by-step explanation:

The point is a solution to this system of inequalities y ≤1/2x-3 and y+2x greater than 6 are B) (2,- 3) and D) (4,1).

To track down the answer for the arrangement of imbalances y ≤ 1/2x - 3 and y + 2x > 6, we want to test each answer decision to check whether it fulfills the two disparities.

A) (7,- 8):

y ≤ 1/2(7) - 3 = 0.5

y + 2(7) > 6

This point doesn't fulfill the primary imbalance, so it's anything but an answer.

B) (2,- 3):

y ≤ 1/2(2) - 3 = - 2

y + 2(2) > 6

This point fulfills the two imbalances, so it is an answer.

C) (5,- 2):

y ≤ 1/2(5) - 3 = - 0.5

y + 2(5) > 6

This point doesn't fulfill the main imbalance, so it's anything but an answer.

D) (4,1):

y ≤ 1/2(4) - 3 = - 1

y + 2(4) > 6

This point fulfills the two imbalances, so it is an answer.

Accordingly, the answers for the arrangement of imbalances are B) (2,- 3) and D) (4,1).

To track down the answer for the arrangement of disparities y ≤ 1/2x - 3 and y + 2x > 6, we really want to test each answer decision to check whether it fulfills the two imbalances. Just response decisions B) (2,- 3) and D) (4,1) fulfill the two imbalances, making them the arrangements.
