Is this a proportional relationship?

Answer:

3

Step-by-step explanation:

the answer is 3, because you always have to add the numbers in paranthises first. and 5+3= 8. u bring down the -5 and you have -5 + 8 = 3.

Answer:

3

Step-by-step explanation:

Always do the stuff in the parentheses first

-5 + (5 + 3)

-5 + 8

= 3

Answer:

Step-by-step explanation:

We can simplify only like terms in an algebraic expression.

Terms are "like terms" only if they consist the same letters with the same exponent.

The only difference between like terms is their coefficients are different.

So:

2y and 2y² are not like terms (different exponents at y)

4x and -3x  are like terms (the same letter, the same exponent)

-3x and 32 aren't like terms (no x with 32 means different exponents)

or if you meant:

-3x and 3z  aren't like terms (different letters)

3z and 4z² aren't like terms (different exponents at z)

Answer:

12a+2b

Step-by-step explanation:

1. Expand by distributing terms.

20a-8b-2(4a-5b)20a−8b−2(4a−5b)

2. Expand by distributing terms.

20a-8b-(8a-10b)20a−8b−(8a−10b)

 3. Remove parentheses.

20a-8b-8a+10b20a−8b−8a+10b

4.Collect like terms.

(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)

5. Simplify.

Answer:

A; the actual length of the land bridge from P to H is 50 yards

Step-by-step explanation:

Here in this case, given the coordinates of P and H, we want to calculate the actual length of the distance between the two points.

Mathematically, to calculate this distance, we make use of the distance formula;

D = √(x2-x1)^2 + (y2-y1)^2

In this case, (x1,y1) = (2,55) while (x2,y2) = (32,15)

Substituting these values

D = √(32-2)^2 + (15-55)^2

D = √(-30)^2 + (-40)^2

D = √(900 + 1600)

D = √(2,500)

D = 50 units

Now, we know that each units represent 1 yard, thus 50 units will represent 50 * 1 = 50 yards

Step-by-step explanation:

Answer:

AB = 42

BC = 78

Step-by-step explanation:

AB = 4x + 6

BC = 7x + 15

AC = 120

A to B plus B to C is the same distance as from A to C, which is 120.

AB + BC = AC

(4x + 6) + (7x + 15) = 120

4x + 7x + 6 + 15 = 120

11x + 21 = 120

Subtract 21 from both sides.

11x = 120 - 21 = 99

11x = 99

Divide both sides by 11.

x = 9

AB = 4x + 6 = 4*9 + 6 = 36 + 6 = 42

BC = 7x + 15 = 7*9 + 15 = 63 + 15 = 78

Answer:

AB = 42

BC = 78

Answer:

x = 9

AB = 42

BC = 78

Step-by-step explanation:

AB + BC = AC

4x + 6 + 7x + 15 = 120

11x + 21 = 120

11x = 99

x = 9

AB = 4x + 6 = 4(9) + 6 = 36 + 6 = 42

BC = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

Answer:

Shoot I don't know but this is as far as I got until I got confused.

Step-by-step explanation:

17b + bx = 24x - a

-17b        =   - 17b

-24x       =   -24x

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

-24x + bx = -17b - a

-24x + bx/b = -17b/b - a/b

-24x + x = -17b - a/b

-23x = -17b - a/b

-23x/-23 = -17b/-23 - a/b/-23

Answer:

1378

Step-by-step explanation:

once you’ve decided on your New Year’s resolutions, the best way to make sure you actually follow through is by developing a plan for how to accomplish your new goals.

For anyone with “saving money” at the top of their list in 2020, the 52-week money challenge is a simple and effective way to stay on track. And at the end of the year, you’ll have $1,378 extra dollars to bulk up your emergency savings or put towards next year’s vacation.

Take some time now to determine what, exactly, you want to save for so you’ll be more motivated to stay the course throughout the year. Once your savings goals are set, jump in and start saving with the 52-week money challenge.

What is the 52-week money challenge?

Using the 52-week money challenge, you should deposit an increasing amount of money each week for one year.

Match each week’s savings amount with the number of the week in your challenge. In other words, you’ll save $1 the first week, $2 the second week, $3 the third week, and so on until you put away $52 in week 52. You can also get creative with the amount you save each week if you’d like to save more over the year or you don’t have enough extra cash available for the regular challenge.

If you stick to this challenge throughout the entire year, you’ll save a total of $1,378.
