If you multiply each side of the equation 5x-3 =7/10 by 10 the result is an equivalent equation

Mathematics

Helga [31]3 years ago

Answer:

Answer in explanation

Step-by-step explanation:

Although , multiplying the both sides of the equation by 10 will yield same equation, it is still the necessary thing to do.

By multiplying both sides by 10, we can easily turn the fraction on the right hand side of the equation to an integer and then we can easily proceed to see the equation solved to completion.

This is the reason why it might be helpful to do this

icang [17]

Answer:

Step-by-step explanation:

The water has to be 100% - 60% = 40%

100% represents both water alcohol (I think that's what you meant).

40% of 250 = 40/100 * 250 = 10000/100 = 100 mL

So 100 mL = water

150 mL = alcohol.

What is the volume of the following triangular prism?
Firdavs [7]

Answer:

Step-by-step explanation:

In order to calculate the volume of a triangular prism you need 2 things:

The triangles area and the prism's height.

Any prism's volume can be calculated by multiplying its base area with its height.

The Area of a triangle can be calculated in different ways.

The most used and "normal" way is:

(width * height) / 2

Another way is by using herons formula, which looks like this:

a, b, c = different sides of the triangle (length)

s = (a + b + c) / 2

a = \sqrt{s (s-a)(s-b)(s-c)}

When you have the prism's base area (b_{a}) you just have to multiply:

b_{a}*h=V

(V = volume)

If you have any questions, just ask them in the comments below.

Solve the equation. 3g - 49 = 7
Alex777 [14]

Answer:

G= 56/3

Step-by-step explanation:

56/3 is an ugly number if you ask me but it was the answer I got, and here's how I got it!

So first off you want to change -49 to a positive and add it to 7! This will change the equation to 3g=56, from here just divide 56 by 3! Which if you don't turn into a fraction it'll just be a really long number. So g=56/3! If you have any more questions feel free to ask!
