Answer: 10

Step-by-step explanation: since dx/dt = 2, you have to create an equation. dx/dt = dy/dt * dx/dy is your equation. now we substitute. 2 = dy/dt *dx/dy. find the derivative of 5x in terms of y (dx/dy), which is 1/5. so now your equation is 2 = dy/dt * 1/5. solve for dy/dt and your answer is 10.  

Answer:

JK

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent

Δ FGH ≅ Δ JKL

The corresponding sides are FG and JK

Answer:

3x - 2y = 7

Where y = x + 2

3x - 2(x + 2) = 7

3x - 2x - 4 = 7

x = 11

Step-by-step explanation:

If you are solving for X and y = x+2 then you write the equation out like this.

3x - 2(x +2) = 7 …. You substitute the x + 2 for y and then solve for x.

2x - 2 times x + 2 times - 2 = 7. That becomes 3x - 2x - 4 = 7. You then subtract 2x from 3x to give you X. Then you add 4 on one side to zero it out and add 4 to the other side. 7 + 4 = 11. This gives you the answer X = 11.

Answer: Subtraction Property

Step-by-step explanation:

For all real numbers x, y and z  

if x = y

then x − z = y − z

please give me a brainliest answer

Answer: O- 9.5 Y- 12.5 R-25

Step-by-step explanation: Divide 25 by 2 and 12 goes into 25 twice for 24, and then you would be left with 60 and 12x5=60 so you get 12.5 for Yellow then you would subtract 3 from 12.5 for 9.5 for Orange. Tell me if theirs anything you dont understand.

Answer:

36 Degrees

Step-by-step explanation:

The definition of an angle bisector is to split the angle into 2 equal parts.

We can then add 18 + 18 degrees to get our original 36 degree angle.

Answer: It would be realistic (yes)

Step-by-step explanation:

A 400 square foot space will be roughly the size of a typical two-car garage, so comparing that to a floor would be completely realistic.

X^6-8

Step-by-step explanation:

Answer:

D) 33 deg.

Step-by-step explanation:

The bottom triangle is an isosceles triangle, and

so the base angles are congruent.

Thus, x = 33 deg.

The scale is 1 inch = 15 feet. Multiply the inches of the drawing by 15to get total feet:

1 2/3 x 15 = 25 feet

2 x 15 = 30 feet

The court is 25 ft by 30 feet

This is smaller than 25 by 75 so it will fit

Answer:

A )Mass -47.9 g

A) Explanation: Based on the given conditions, formulate: x + 2 ×58.35 = 68.8

Calculate the product or quotient: x + 116.7 = 68.8

Rearrange unknown terms to the left side of the equation: x = 68.8 - 116.7

Calculate the sum or difference: x = - 47.9

get the result:x = - 47.9

Answer: x = - 47.9

Answer:

50L is larger than 500 ML because 1L=1000ml and. 1ML= 1 ML.

Step-by-step explanation:

Answer: 50 L

Step-by-step explanation:

In order to compare both, let's first transform 500 mL into L. We know that 1 L is 1000 mL. So 500 mL = 0.5 L. We should now look at both numbers. The answer would be 50 L, since 50 is superior to 0.5
