Answer:

x = $\frac{7}{12}$

Step-by-step explanation:

Given

$\frac{x}{\frac{7}{8} }$ = $\frac{2}{3}$ ( cross- multiply )

3x = 2 × $\frac{7}{8}$ = $\frac{7}{4}$ ( divide both sides by 3 )

x = $\frac{7}{12}$

Answer: The number that goes in the green box is 7

Step-by-step explanation: The LHS of the equation can also be expressed as,

x/ (7/8) OR

x times (8/7)

That is, 8x/7

In other words, the equation now becomes;

8x/7 = 2/3

By cross multiplication we now have

8x(3) = 7(2)

24x = 14

Divide both sides of the equation by 24

x = 14/24

(Simplified further)

x = 7/12

Therefore the number that goes in the green box is 7.

Find the equation of the line that is perpendicular to y=-2x+1 and contains the point (8, 2).

AleksAgata [21]

Answer:

y = 1/2x - 2

Step-by-step explanation:

In order for a line to be perpendicular to another, the lines must have opposite reciprocal slopes.

Example of an opposite reciprocal slope: -2 ⇒ 1/2

Insert the information into the point-slope formula:

$y-y_1=m(x-x_1)\\\\y-2=\frac{1}{2}(x-8)\\\\y-2=\frac{1}{2}x-4\\\\y=\frac{1}{2}x-2$

Question 6(Multiple Choice Worth 1 points)

Vsevolod [243]

Answer:

q = ³√64

(cube root 64 )

explanation :

we have to find the value of q but it's given q³ so to find the value of only q we send ³ to other side and it turns into cube root

for example :

like when it's q² = 64 it will be q = ²√64

Olenka [21]

Answer:

He have 47 ducks and 7 cows.

Step-by-step explanation:

Given:

Farmer Jones raises ducks and cows.

He looks out his window and sees 54 animals with a total of 122 feet.

Now, to find the each type of animal he have.

Let the number of ducks be $x.$

And the number of cows be $y.$

So, total number of animals are:

$x+y=54$

$x=54-y$ ....( 1 )

As, the feet of cows are 4 and ducks are 2.

Now, the total number of feet are:

$2(x)+4(y)=122$

$2x+4y=122$

Substituting the value of $x$ from equation (1) we get:

$2(54-y)+4y=122$

$108-2y+4y=122$

$108+2y=122$

Subtracting both sides by 108 we get:

$2y=14$

Dividing both sides by 2 we get:

$y=7.$

The number of cows = 7.

Now, to get the number of ducks we substitute the value of $y$ in equation (1):

$x=54-y\\x=54-7\\x=47.$

The number of ducks = 47.

Therefore, he have 47 ducks and 7 cows.
