28 - 2 (5a - 3) = 47

Answer: a=-1.3

Step-by-step explanation:

1) Reorder the terms: 28 + (-3 * -2 + 5a * -2) = 47

28 + (6 + -10a) = 47

2) Solving: 34 + -10a = 47

3) Add -34 to each side of the equation: 34 + -34 + -10a = 47 + -34

4) Combine like terms: 34 + -34 = 0: 0 + -10a = 47 + -34

-10a = 47 + -34

5) Combine like terms: 47 + -34 = 13: -10a = 13

6) Divide each side by -10: a = -1.3

The volume of the first cube is (5h^2)^3, while the volume of the second cube is (3k)^3, so their total volume is (5h^2)^3 + (3k)^3. We can use the special formula for factoring a sum of two cubes:
x^3 + y^3 = (x + y)(x^2 - xy + y^2)
(5h^2)^3 + (3k)^3 = (5h^2 + 3k)((5h^2)^2 - (5h^2)(3k) + (3k)^2)
= (5h^2 + 3k)(25h^4 - 15(h^2)(k) + 9k^2)
This is the second of the given choices.

Together, Kyle and Tyler traveled 425 miles to the beach. If Kyle traveled 240 miles, how far did Tyler travel?
Papessa [141]

Answer:

185 miles

Step-by-step explanation:

We are given that

Both Kyle and Tyler traveled total  distance to the beach=425 miles

Kyle traveled distance to the beach=240 miles.

We have to find the distance traveled by Tyler.

To find the distance traveled by Tyler we will subtract distance traveled by Kyle form total distance traveled by together Kyle and Tyler.

Let x be the distance traveled by Tyler.

According to question

x+240=425

x=425-240=185 miles

Hence, Tyler travels distance to the beach=185 miles

juin [17]

Answer:

12 weeks

Step-by-step explanation:

Josiah and kiri are each saving money josiah starts with 100$ in savings accound and adds 5$ per week . Kiri with 40$ in her savings account adds 10$ each week after how weeks Josiah and kiri will have the same amount of money in their savings account

Josiah:

100 + 5w

Kiri:

40 + 10w

Where,

w = number of weeks

After how weeks Josiah and kiri will have the same amount of money in their savings account

Equate the savings of the both of them

100 + 5w = 40 + 10w

100 - 40 = 10w - 5w

60 = 5w

w = 60/5

= 12

w = 12 weeks

Josiah and kiri will have the same amount of money in their savings account after 12 weeks
