5 ( 3x - 2) = 4 ( 2x + 1)

Answers

Answer:

15x-2=8x+1

13x=9x

i think that's correct im not sure but i hope to help u :)

5(3x-2)=4(2x+1)
(15x-10)=(8x+4)
7x-10=4
7x=14
X=2
Explanation:
I multiplied everything inside the parenthesis by the number on the outside, making the equation 15x-10=8x+4, then I combined like terms, so I subtracted 8x on both sides and added 10 to each side, making the equation 7x=14, this means that 14/7 and 7/7 is the last step, which leaves you with the answer of x=2

The soccer team and the American football team are sharing the field for their practices today. The
soccer team meets for practice every 2 days, and the American football team meets every 4 days. How
many days from now will they have to share the field again?

Answers

Answer:

4

Step-by-step explanation:

We can find the LCM of the 2, being 4.

Answer: 4 days later

The soccer team goes every two days. The American football team goes every 4 days.

After one time of soccer practice, next time the football team will be there.

The football team goes every four days, so after one day of soccer practice, the Football team has to share the field.

Find the sum or the difference a. -2.63+3/1/4

Answers

Answer:

-1.88

Step-by-step explanation

Put both terms in decimal form. -2.63 is already in decimal form, so, you only have to put 3 1/4 in decimal form.

So, -2.63+0.75=-1.88

1. 8x+15=dx-20

2. 12(7+2y)=4y-(3-ty)

3. 15+x(3t-4)=8(-2t+11)


:) answer all for brainliest

Answers

8x+15=dx-20

8x+15+20=dx

8x+35=dx

d=​8x+35 /x

12(7+2y)=4y-(3-ty)

12(7+2y)=4y−3+ty

12(7+2y)−4y=−3+ty

12(7+2y)−4y=ty−3

12(7+2y)−4y+3=ty

t= ​12(7+2y)−4y+3 /​y

15+x(3t-4)=8(-2t+11) SOLVING FOR X

Solve inequality 5-3(4x-5)<32

Answers

Answer: x > -1

Step-by-step explanation:

1) Subtract 5 from both sides

-3(4x - 5) < 27

2) Divide both sides by -3 (Remember to change the inequality sign to face the other way, because you have multiplied/divided by a negative number)

4x - 5 > -9

3) Add 5 to both sides

4x > -4

4) Divide by 4 on both sides

x > -1

Stephen, Gavin and Jim share some sweets in the ratio 3:1:2. Stephen gets 24 sweets. How many sweets are there altogether?

Answers

Answer:

Step-by-step explanation:

Stephen : Gavin : Jim

3 : 1 : 2

We can say that this means the total amount of sweets get split between the 3 of them into 6 equal parts ( 3 + 1 + 2).

If Stephen gets 24 sweets, this means

3 parts = 24

So to find 1 part, divide 24 by 3.

1 part = 8 sweets

Now we can find the total by multiplying this by 6.

6 parts = 8 x 6 = 48 sweets.

On the last day of summer vacation, many people are on the beach, and Hilary realizes that she can make a lot more money this day if she hires someone to walk up and down the beach selling water.
