X = number of loads
company A : 20x + 8
company B : 24x + 4

20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less

20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A

Answer:

Part A : 20x + 8 and 24x + 4

Part B : Company A charges less and compared to company B.

Part C : Using the services of company A saving is $32

Step-by-step explanation:

Jake is comparing the prices of two laundry service companies.

Part A:

Company A charges $20 per load and an additional $8 as service charges.

So the expression that represents the charges = 20x + 8

Similarly for company B the expression will be charges = 24x + 4

Here x represents the number of loads of the laundry.

Part B:

In this part we have to compare the charges for 5 loads of the laundry.

Charges of company A : 20x + 8 = 20×5 + 8 = $108

Charges of company B : 24x + 4 = 24×5 + 4 = $124

Therefore, company A charges less.

Part C :

Company A charges for 9 loads = 20×9 + 8 = $188

and company B charges for 9 loads = 24×9 + 4 = $220

Saving by using the services of company A instead of company B

= 220 - 188

= $32

Do not use spaces in your answer. Solve for x. -5x + 12x - 8x = -24 x = ___ a0
const2013 [10]

Answer:

\Huge \boxed{x=24}

Step-by-step explanation:

-5x + 12x - 8x = -24

Combine all like terms.

(-5+ 12- 8)x = -24

-x=-24

Multiply both sides by -1.

x=24

19. If the pg", and "terms of an A.P. are a,b, and c respectively. prove that: p(b-c) + (ca) + rſa-b) = 0 50 Approved by Curricu
professor190 [17]

Answer:

Step-by-step explanation:a = m + (p-1)*d

b = m + (q-1)*d

c = m + (r-1)*d

p(b-c) = p*(q-r)*d

q(c-a) = q*(r-p)*d

r(a-b) = r*(p-q)*d

p(b-c)+q(c-a)+r(a-b)

= p*(q-r)*d + q*(r-p)*d +r*(p-q)*d

= (pq-pr+qr-pq+rp-qr)*d

= 0*d = 0

So i prove p(b-c)+q(c-a)+r(a-b)=0 hope this is helpfull

I need to know the answer
antoniya [11.8K]
2 days late, but the answer is no solution. solving a system of equations means finding where they intersect, but by looking at these equations, you know that they never intersect--they're parallel.

they share a slope (2), making them either parallel or "the same line", but the different x-intercepts (9 and -9) mean that they're different lines. they have no solution, or no intersection point, because they're parallel lines.

Need help with my math simplify
nlexa [21]

2+42/-2-5(-3)  Multiply -5 and -3.

2+42/-2+15 Now, add the non fraction numbers. (2 and 15)

17+42/-2 Here, you want to reduce the fraction if you can, and yes, you can. Find the divisible number that is the lowest one that both can be evenly divided by. For this problem, it’s -2.

17-21. And from here, its easy. Just a simple subtraction problem.

-4 should be the correct answer.
