Answer:

The answer should be y=2x-4.

Step-by-step explanation:

What does A equal to

ruslelena [56]

Since you know that PQ=RQ, you have an equilateral triangle. This makes things very simple.
Angle R should be the same as angle P.
A triangle is equal to 180 degrees.
Add angles P and R. Subtract 180 from the answer you got. That will give you 2a. a divided by 2 will give you a.

Or, since there are two right triangles, you can add 47 and 90. Subtract 180 from that and you will get a.

Do you know the inequality? Please explain and show answer :)

DerKrebs [107]

If u have a open circle, then the inequality has no equal sign. But if it is a closed circle, the inequality has an equal sign.
Shading to the left means " less then " .
Shading to the right means " greater then " .

(1) u have an open circle on -7 with shading to the left....
x < -7

(2) u have a closed circle on 4.5 with shading to the left....
x < = 4.5 (thats less then or equal)

(3) u have an open circle on -5 with shading to the right...
x > -5

(4) u have an open circle on 1.5 with shading to the right...
x > 1.5

Find the missing dimension of each prism.

Leto [7]

Given:

Volume of the prism = 60 in³

Breadth = 2.5 in

Height = 4 in.

To find:

The length of the prism.

Solution:

We know that, volume of a prism is

$V=l\times b\times h$

where, l is length, b is breadth and h is height.

Putting V=60, b=2.5 and h=4, we get

$60=l\times 2.5\times 4$

$60=l\times 10$

Divide both sides by 10.

$\dfrac{60}{10}=l$

$6=l$

Therefore, the missing dimension of the prism is 6 in.

What percent of 75 is 40

9966 [12]

The answer is: " 53 $\frac{1}{3}$ % " .

__________________________________________

→ " 53 $\frac{1}{3}$ % " of 75 is "40" .

__________________________________________

Explanation:

To solve:

$\frac{x}{100}$ * 75 = 40 ;

→ Rewrite as:

$\frac{x}{100}$ * $\frac{75}{1}$ = 40 ;

→ The "100" cancels to "4" ; and the "75" cancels to "3" ;

→ {since: "{100 ÷ 25 = 4}" ; and since: "{75 ÷ 25 = 3"} ;

→ So; we rewrite the problem as:

→ $\frac{x}{4}$ * $\frac{3}{1}$ = 40 ;

→ which is:

$\frac{x}{4}$ * 3 = 40 ;

→ Divide each side of the equation by "3" ;

$\frac{x}{4}$ * 3 ÷ 3 = 40 ÷ 3 ;

to get:

→ $\frac{x}{4}$ = $\frac{40}{3}$ ;

Now, cross-multiply:

→ 3x = (4)*(40) ;

→ 3x = 160 ;

Divide each side of the equation by "3" ;

to isolate "x" on one side of the equation; & to solve for "x" ;

→ 3x / 3 = 160 / 3 ;

to get:

→ x = 53 $\frac{1}{3}$ .

Devin paid $30 to be a member of the fox lake gym. When he takes the boxing class, it costs him $2. Jared is not a member of the

Paha777 [63]

For this case, the first thing we must do is define variables.

We have then:

x: number of classes:

y: total cost

For Devin we have the following equation:

$y = 2x + 30$

For Jared we have:

$y = 5x$

Then, by the time the cost of both is the same, we have:

$2x + 30 = 5x$

From here, we clear the value of x.

We have then:

$5x - 2x = 30$

$3x = 30$

$x = \frac{30}{3}$

$x = 10$

Answer:

it takes 10 classes for Devin's total cost to equal Jared's total cost
