How many solutions does the following equation have (6x +12) =-18

Answers

Answer 1

Answer: ( 6 x + 12 ) = -18

6 x + 12 = - 18

6 x = - 18 - 12

6 x = - 30

x = - 30 / 6

x = -5

only 1 solution

What is -4x+8=48 what is x

Answers

Subtract 8 from each side:

-4x = 40

Divide each side by -4 :

x = -10

X= -10

-4x+8=48

Subtract 8 on both sides so it would be -8

Then rewrite the equation and it should be

-4x/-4 = 40/-4

Which equals -10

7 x 3/4

Answers

If you would like to calculate 7 * 3/4, you can do this using the following steps:

7 * 3/4 = 21/4 = 5 1/4

The correct result would be 21/4.

The equivalent value of the expression is A = 21/4

Given data:

The first number is represented as a = 7

The second fraction is represented as b = 3/4

So, the equation is A = ab

And, A = 7 x 3/4

So, 7 multiplied by 3/4 equals 21/4.

However, to express the answer in its simplest form, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor.

The greatest common factor of 21 and 4 is 1, so we divide both numerator and denominator by 1.

Hence, the simplest form of the equation is A = 21/4

In a school, the ratio of musicians to athletes is 3:1. which statement is true13 of the total students are musicians.

If there are 18 people, then 12 of them are athletes.

If there are 3 athletes, then there are 12 musicians.

The number of musicians is 3 times the number of athletes

Answers

I think the correct answer from the choices listed above is the last option. In a school, the ratio of musicians to athletes is 3:1. This means that the number of musicians is 3 times the number of athletes. Hope this answers the question. Have a nice day.

Answer: The answer is (D) The number of musicians is 3 times the number of athletes.

Step-by-step explanation: Given that the ratio of musicians to athletes in a school is 3 : 1. We are to select the correct statement out of the given four options.

Since the total number of people are not given, so we cannot say that 13 of them are musicians. Therefore, option (A) is incorrect.

If there are 18 people, then number of athletes is given by

$(x)/(x+3x)* 18=4.5\neq 12,$

and hence the option (B) is not correct.

If there are 3 athletes, then

x=3, and so the number of musicians = 3 × 3 = 9 ≠ 12. Therefore, the option (C) is not correct.

Number of musicians = 3x = 3 × x = 3 × number of athletes.

Thus, the correct option is (D) The number of musicians is 3 times the number of athletes.
