Mathematics
1 answer:
WINSTONCH [101]2 years ago
8 0

Answer:

D

Step-by-step explanation:

Providing it is written as 1 * x / 5 - 2*y / 3 = 30, it can be solved this way.

x/5 - 2*15/3 = 30

x/5 - 10 = 30  

x/5 = 30 + 10

x/5 = 40

(x/5)*5 = 40*5

x = 200

Answer D

<h3 />

The given ratios are:-

Mixture A = \dfrac{5}{12} = 0.41

Mixture B = \dfrac{6}{6}= 1

Mixture C = \dfrac{4}{12}= 0.33

Mixture B = \dfrac{5}{6}=0.83

Here the ratio of mixture B is the highest among all the options available.

What is the solution for the system of equations {9x+8y=3 6x−12y=−11?
lions [1.4K]

Answer:

( - \frac{1}{3}, \frac{3}{4} )

Step-by-step explanation:

Given the 2 equations

9x + 8y = 3 → (1)

6x - 12y = - 11 → (2)

To eliminate the y- term multiply (1) by 1.5

13.5x + 12y = 4.5 → (3)

Add (2) and (3) term by term

(6x + 13.5x) + (- 12y + 12y) = (- 11 + 4.5)

19.5x = - 6.5 ( divide both sides by 19.5 )

x = \frac{-6.5}{19.5} = - \frac{1}{3}

Substitute this value into either of the 2 equations and solve for y

Using (1), then

- 3 + 8y = 3 ( add 3 to both sides )

8y = 6 ( divide both sides by 8 )

y = \frac{6}{8} = \frac{3}{4}

Solution is (- \frac{1}{3}, \frac{3}{4} )
