Answer:

4a + 4b = 10

6a + 6b = 12

Step-by-step explanation:

Putting the equation in a system of linear equation :

We donate, apples and oranges using any preffered letter or alphabet

Let :

Apples = a ; oranges = b

4 apples and 4 oranges equals $10

4a + 4b = 10

6 Apples and 6 oranges equals $12

6a + 6b = 12

Hence, the system of linear equation :

4a + 4b = 10

6a + 6b = 12

Juanita wants to perform row operations on the augmented matrix for the system below (See pictures). Which matrix should Juanita
Artist 52 [7]

Answer:

The second option

Step-by-step explanation:

The given system of equation is

x+2y=3

-x+y+z=2

y-2z=-3

The augment matrix is obtained by combining the coefficient matrix with the constant matrix to obtain;

\left[\begin{array}{cccc}1&2&0&|3\\-1&1&1&|2\\0&1&-2&|-3\end{array}\right]

Note that the absence of z, in the first equation means its coefficient is zero. The same thing applies to x in the last equation.

The correct choice is the second option.

Given right triangle XYZ, what is the value of tan(60°)?
Svetlanka [38]

we know that

Step 1

in the right triangle XYZ

Applying the Pythagorean Theorem

Find the value of ZY

XY^{2}=XZ^{2} +ZY^{2} \\   ZY^{2}=XY^{2}-XZ^{2}\\ ZY^{2}=42^{2}-21^{2}\\ ZY^{2}=1,323\\ ZY=\sqrt{1,323}\ units

ZY=21\sqrt{3}\ units

Step 2

in the right triangle XYZ

Find tan60°

we know that

tan\ 60=\frac{opposite\ side\ angle\ 60}{adjacent\ side\ angle\ 60}

in this problem

opposite side angle 60 is ZY

adjacent side angle 60 is XZ

so

tan\ 60=\frac{ZY}{XZ} \\ \\ tan\ 60=\frac{21\sqrt{3}}{21}  \\ \\  tan\ 60=\sqrt{3}

therefore

the answer is

\sqrt{3}

Amount Marvin get on a discount coupon = $25

She decided to buy insurance for each day.

Let the number of days be x

cost of insurance = $465

According to question, it becomes,

25x=465\\\\x=\frac{465}{25}\\\\x=18.6\\\\x=19\ days

Hence, Marvin needs approximately 19 days to rent the car.
