A number is multiplied by 7. Then 29 is added to the product. This sum is then divided by 2. The answer is 46. What was the original number? Student's solution - The answer was 46. If this was the result of dividing by 2, the number at this point was 92. If this was the result of adding 29, the number at this point was 63. If this was the result of multiplying by 7, the original number was 9. Solve this problem using a similar strategy. A number is multiplied by 10. Then 32 is added to the product.

For a client, a landscaper purchases 3 oak trees and 4 maple trees for $380. For his own home, the landscaper purchases 2 oak trees and 5 maple trees for $370. Which augmented matrix represents the situation?

Answers

You don't have any choices here, but it's easy to determine what your matrix would look like by first writing the equations. Oak trees is x and maple trees is y. The first of our equations then is 3x + 4y = 380 and the second is 2x + 5y = 370. In matrix form, that would be $\left[\begin{array}{ccc}3&4\n2&5\end{array}\right]= \left[\begin{array}{ccc}380\n370\n\end{array}\right]$

The augmented matrix represents the situation that will be, $\left[\begin{array}{ccc}3&4\n2&5\n\end{array}\right]$ .

What is an augmented matrix?

The columns of two matrices are combined to create a new matrix known as an augmented matrix.

When using matrices to solve straightforward linear equations, the augmented matrix is a crucial tool. The number of variables in the linear equation is the same as the number of rows in the augmented matrix.

Let us consider x is the oak tree and y is the maple tree then;

⇒3 oak trees and 4 maple trees for $380;

⇒3x+4y = 370

⇒Purchases 2 oak trees and 5 maple trees for $370;

⇒2x+5y=370

The two equations are expressed in the matrixas;

$\left[\begin{array}{ccc}3&4\n2&5\n\end{array}\right]$

Hence, the augmented matrix represents the situation that will be, $\left[\begin{array}{ccc}3&4\n2&5\n\end{array}\right]$ .

The formula for the area A of a trapezoid is A=1/2(b1+b2)h, where b1 and b2 represents the lengths of the bases and h represents the height. Which equation can be used to find the height of a trapezoid?A. h=2A-b1-b2
B. h=2A/b1+b2
C. h=A(b1+b2)/2
D. h=A-2/b1-b2

Answers

The answer: [B]: h = 2A / (b1 + b2) .
__________________________________________________________
Explanation:

Given: A = (½) * (b1 + b2) * h ;
________________________________
→Multiply EACH side of the equation by "2", to get rid of the fraction, "½";
____________________________________________________________
→ 2*A = 2 * (½) * (b1 + b2) * h ;

→ 2* A = 1 * (b1 + b2) * h ;

→ 2A = (b1 + b2) * h ;
____________________________
→ Now, divide EACH side of the equation by: "(b1 + b2)" ; to isolate "h" on one side of the equation;
__________________________________________________________
→ 2A / (b1 + b2) = [(b1 + b2) * h] / (b1 + b2) ;

→ 2A / (b1 + b2) = h ; ↔ h = 2A / (b1 + b2) ; which corresponds to:
"Answer choice: [B]" .
