Answer:

35 students

Step-by-step explanation:

If there are 4 girls, then there are 3 boys

You will multiply both by 5 to get 20

So 3×5 is 15

20+15 = 35

Answer: 35 students

Explanation: Divide 4 into 20 to see how many sets of 4 girls there are. So there are 5 sets of four girls.

Five times three is 15.

In total (15 + 20), there are 35 students.

Answer:

Step-by-step explanation:

x^2 - 4x - 5 = 0

(x - 5)(x + 1) = 0

x - 5 = 0

x = 5

x + 1 = 0

x = -1

We want to find the roots of a quadratic equation, to do that, we will use the Bhaskara's formula.

For an equation like a*x^2 + b*x + c = 0

The solutions are given by:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

Using that formula we will get that the solutions in ascending order are -1 and 5.

Now let's see how to get that:

We have expression: x^2 - 4x = 5

We can rewrite this as:

x^2 - 4x - 5 = 0

Now we can use the Bhaskara's formula to get:

[tex]x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*(-5)} }{2*1} = \frac{4 \pm6}{2*1}[/tex]

Then the two solutions are:

x = (4 + 6)/2 = 5

x = (4 - 6)/2 = -1

Then the solutions in ascending order are -1 and 5.

Answer: x = 15

Step-by-step explanation:

1) Set q(x) = 3 in the equation.

3 = (4/5)x - 9

2) Add 9 to both sides.

12 = (4/5)x

3) Multiply by 5/4 on both sides.

15 = x

x = 15

Answer:

x=1/8

Step-by-step explanation:

First we need to isolate the variable. We can do that by subtracting 3 from each side. You then get: 24x-2=1. Then, to completely isolate it, add 2 to each side. We get 24x=3. Now divide 24 from each side to get only x. We get 3/24, which can be rewritten as 1/8.

Answer:

there are no x values of X that make the equation true

Step-by-step explanation:

The given equation is not the same on the left-hand side as on the right-hand side so there will be no solution or the equation is wrong.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

Given the equation

4x + 8 = 4x - 3

Subtract 4x from both sides

4x + 8 - 4x = 4x - 3 - 4x

(4x - 4x) + 8 = (4x - 4x) - 3

8 ≠ 3

Since it is not satisfying so it will not have any solution.

Hence "The given equation is not the same on the left-hand side as on the right-hand side so there will be no solution".

Answer:

w(15)=112.5

Step-by-step explanation:

All you have to do is put the number in the parentheses in the place of the variable, which in this case is h, and perform the prescribed operation.

In this case, you make the equation w(15)=7.5(15) which you can rewrite as

                                                                                  w(15)= 7.5×15, which gives                        .                                                                                  you 112.5 as the product.

Answer:

The submarine is at -1260 ft.

It descends 5 ft/min for 12 min.

12 min * 5 ft/min = 60 ft.

It descended 60 ft, so you must subtract 60 ft from -1260 ft.

-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft

The error in the last line in the problem is that (-5)(12) = -60, not 60.

The correct line is:

-1260 + (-5)(12) = -1260 - 60 = -1320

Answer:

Your answer is: x = -9
