Four times a number, subtracted from nine, is twice the number. How do I solved this?
Natalija [7]

4x - 9 = 2x


Solve for x.

4x = 2x + 9

2x = 9

x = 4.5

We can plug 4.5 into the original equation to verify if it's correct.

4x - 9 = 2x

4(4.5) - 9 = 2(4.5)

18 - 9 = 9

The equation is true, and so x = 4.5

yaroslaw [1]

Answer:

x = 11

Step-by-step explanation:

(0.3x - 2.1)/3 = 0.4

0.3x - 2.1 = 0.4 * 3

0.3x - 2.1 = 1.2

0.3x = 1.2 + 2.1

0.3x = 3.3

x = 3.3/0.3

x = 11

How are the formulas for the area of a rectangle and the area of a triangle alike and different? And wolflover14, it's Nini on a
RoseWind [281]

Answer:

The formula to find the area of a rectangle is:

b * h = a

where b = base, h = height, and a = area.

The formula to find the area of a triangle is:

(1/2) * b * h = a

where b = base, h = height, and a = area.

They are similar because in both of the formulas, you are multiplying the base by the height. The difference is that in the triangle formula, you have to do an additional step of multiplying by (1/2) to get the area. hope this helps:)
