1 answer:

7 0

I’m not sure if the 2 is counted in the equation or not

Since x=4, substitute it for x in the other equation

4+3y=29
3y=25
Y=8.333333333

2(4)+3y=29
8+3y=29
3y=37
y=12.33333333

Answer:

864 ft^2.

Step-by-step explanation:

Area of the base = 16^2 = 256.

Area of the triangular sides = 4 * 1/2 * 16 * 19

Total area = 256 + 608

= 864 ft^2.

Answer:

x = - 9, y = -1

Step-by-step explanation:

Given:

$\begin{bmatrix}x-2y=-7\\ -3x-2y=29\end{bmatrix}$

Solve:

$\mathrm{Substitute\:}x=-7+2y$

$\begin{bmatrix}-3\left(-7+2y\right)-2y=29\end{bmatrix}$

$\begin{bmatrix}21-8y=29\end{bmatrix}$

$\mathrm{For\:}x=-7+2y$

$\mathrm{Substitute\:}y=-1$

$x=-7+2\left(-1\right)$

$x=-9$

$\mathrm{Thus, Answer:x=-9,\:y=-1}$

Kelly is 3 years younger than her sister. The sum of their ages is 34 years. How old is Kelly and how old is her sister? AN EQUA

KiRa [710]

Kelly's sister is x years old.
Kelly is 3 years younger than her sister, so Kelly is x - 3 years old.
The sum of their ages is x + x - 3 = 2x - 3.
The sum of their ages is 34, so

2x - 3 = 34

2x = 37

x = 18.5 Kelly's sister's age.

x - 3 = 18.5 - 3 = 15.5 Kelly's age.

Kelly's sister is 18.5 years old.
Kelly is 15.5 years old.
