3-5(x+4)=8(2x-3) how to solve this equation

Answers

Answer:3

Step-by-step explanation:

Final answer:

The solution to the equation 3-5(x+4)=8(2x-3) is x = 1/3. The solving process involves distributing, collecting similar terms, isolating variables, and finally simplifying.

Explanation:

To solve the equation 3-5(x+4)=8(2x-3), we need to follow a few steps:

Start by simplifying both sides of the equation. This step would involve the use of the distributive property.
Distribute 5 into the parenthesis on the left side to get 3 -5x -20. In the same way, distribute 8 into the parenthesis on the right side to get 16x -24.
The simplified equation would then be: -5x -17 = 16x -24.
Next, get all the x terms on one side (by adding 5x to both sides) and the constants on the other side (by adding 24 to both sides). This gives us 21x = 7.
Finally, to isolate x, divide both sides by 21 to get x = 7/21, which simplifies to x = 1/3.

four students spent $12 on school lunch .at this rate,find the amount 10 students would spend on the same school lunch

Answers

In order to solve this, we need to figure out how much ONE student spends.
$(12dollars)/(4students) = 3$ dollars per student.

If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
$10students* (3dollars)/(student) = 30dollars$

ok so you will multiply 12 times 10 or you could add 12 + 12+12+12+12+12+12+12+12+12 add them up and it will be $120

5% as a decimal and fraction

1) To make 5% to decimal you have to divide 5% by 100. Percent means something out of 100.

⇒ 5% ÷ 100 = n
n = 0.05

5% as a decimal = 0.05

5% as a fraction

1) Percent is always out of 100 so 5% would be out of 100
⇒ 5% = 5/100

The fraction of 5% is 5/100
5/100 can be reduced
To reduce a fraction you have to divide by the greatest common factor

The greatest common factor of 5 and 100 is 5.

5 ÷ 5 = 1
100 ÷ 5 = 20

5/100 in simplest form would be 1/20
