I did the work and it says 0.3683492496 and more number but i believe its 0.3 without all those other numbers
La fórmula para encontrar el área de un rectángulo es b*h.
el problema nos dice que la base mide 8 metros y que su altura es 3 veces lo que mide la base por lo que sería 3 veces 8 o 3x8 = 24
Teniendo ya los datos de medida de la base y la altura, podemos determinar el área la cual es igual a 8 X 24 = 192 cm².
Answer:
equation ---> 120+10(m)=150+4(m)
m= number of months
(By the way the answer would be 5 months)
Step-by-step explanation:
Answer
Find out the what fraction of the sandcastle did they build together .
To prove
Let us assume that the fraction of the sandcastle they build together be x .
As given
![Beatrice\ built\ about\ \frac{1}{3}\ of\ a\ sandcastle.](https://tex.z-dn.net/?f=Beatrice%5C%20built%5C%20about%5C%20%5Cfrac%7B1%7D%7B3%7D%5C%20of%5C%20a%5C%20sandcastle.)
![Linda\ built\ \frac{4}{7}\ of\ the\ same\ castle.](https://tex.z-dn.net/?f=Linda%5C%20built%5C%20%5Cfrac%7B4%7D%7B7%7D%5C%20of%5C%20the%5C%20same%5C%20castle.)
Than the equation becomes
![x = \frac{1}{3} +\frac{4}{7}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%2B%5Cfrac%7B4%7D%7B7%7D)
L.C .M of (3,7) = 21
solving
![x = \frac{7 + 3\times4}{21}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B7%20%2B%203%5Ctimes4%7D%7B21%7D)
![x = \frac{19}{21}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B19%7D%7B21%7D)
Therefore the fraction of the sandcastle did they build together be
![x = \frac{19}{21}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B19%7D%7B21%7D)
Hence proved
Answer:
- (5/3, 14/3) or (1.66, 4.66)
Step-by-step explanation:
<u>Given system of equations</u>
The solution is the intersection point of the lines
<u>Determine x- coordinate:</u>
- 4x - 2 = x + 3
- 4x - x = 3 + 2
- 3x = 5
- x = 5/3
<u>Determine y- coordinate:</u>
- y = x + 3
- y = 5/3 + 3 = 14/3
<u>So the point is:</u>
- (5/3, 14/3) or (1.66, 4.66)
