Answer:

Step-by-step explanation:k so high school total should be 100%

                                            middle school not taken SAT should be 63%

                                            high school have taken SAT should be 96%

basically just use your basic math. Turn the problem around and take the total(100%) and subtract what number you already know. So like This:

                                                                                                100-37=63

                                                                                                100-4=96

Whats is f (5) = 2x + 17​
Artemon [7]

Answer:

f(5)=27

Step-by-step explanation:

The 5 in the f(5) just means thats what x is equal to, so using that information you can do 2(5)+17=27, so f(5)=27. (Sorry if its short)

Solve this system of linear equations. Separate
attashe74 [19]

Answer:

(-\frac{7}{13},\frac{79}{13})

Step-by-step explanation:

Given:

Two equations are given.

- 7x + 3y = 22------(1)

4x + 2y = 10----------(2)

Solve equation 1 for y.

- 7x + 3y = 22

3y = 22+7x

y=\frac{22+7x}{3}-----------(3)

Now, we substitute y value in equation 2.

4x + 2(\frac{22+7x}{3}) = 10

\frac{12x + 2(22+7x)}{3} = 10

12x + 2(22+7x)=10\times 3

12x + 44+14x=30

26x=30-44

26x=-14

x=-\frac{14}{26}

x=-\frac{7}{13}

Now, we substitute x value in equation 1.

- 7(-\frac{7}{13}) + 3y = 22

\frac{7\times 7}{13} + 3y = 22

\frac{49}{13} + 3y = 22

3y = 22-\frac{49}{13}

3y = \frac{13\times 22-49}{13}

3y = \frac{286-49}{13}

y = \frac{237}{13\times 3}

y = \frac{237}{39}

y = \frac{79}{13}

Therefore, the value of x and y is (x=-\frac{7}{13},y = \frac{79}{13})
