To get the area of the triangle you have to multiply 50x1 which is 50 and divide 50 divided by 2 which is 25 and that is he area of the angle
For this case, the first thing we must do is define variables.
We have then:
x: number of years of Joan y: number of years of ellen We now write the system of equations:

Solving the system we have:

So that Joan is 21 years old then:
Answer: joan will be 21 years old in 12 years
Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
y = 
2 is canceled on the left side which gives the solution for Y.
y = 2
Answer:
4x^2
Step-by-step explanation:
Call the unknown side y
The area of the figure is
8x^3 *y = 32 x^5
Divide each side by 8 x^3
8x^3 *y / 8x^3 = 32 x^5 / 8x^3
y = 4 x^2
The unknown side is 4 x^2
To regroup is to use place value to exchange equal amount when renaming a number.
