Answer:

The solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .

Option (D) is correct .

Step-by-step explanation:

As given the equations are .

4x+y=5

3x+y=3

Subtracted 3x+y=3 from 4x+y=5 .

Thus

4x - 3x + y - y = 5 - 3

x = 2

Put in the equation 4x+y=5 .

4 × 2 + y = 5

8 + y = 5

y = -8 + 5

y = -3

Therefore the solution of the equation 4x+y=5 and 3x+y=3 be (2 , -3) .

Option (D) is correct .

The percentage change of a ratio of two variables is approximately the percentage change in the numerator _____ the percentage c

olchik [2.2K]

Answer:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator minus the percentage change in the denominator."

Step-by-step explanation:

The percent change in a number is determined by dividing the difference between the new number and original number by the original number and multiplying the result by 100.

Suppose the original ratio of two numbers is: $\frac{25}{100}$ .

And the new ratio is: $\frac{75}{100}$

The percent change is:

$Change\%=\frac{75-25}{100}\times100=\frac{50}{100}\times100=50\%$

Thus, the complete statement is:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator minus the percentage change in the denominator."

Feliz [49]

Answer:

15 goals out of 50 penalty kicks was scored by brock

Step-by-step explanation:

If Brock shoots 50 penalty kicks and the probability that he scores a penalty kick is 3/10, the number of goal brock is expected to make can be expressed as:

Number of goals scored = probability value * total penalty kicks taken

Number of goals scored = $\frac{3}{10}*50$

Number of goals scored = $15 goals$
