ok sweetheart so basicaly what u do is...

Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator

Answer:

This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".

I need to find the measure of angle A

Answers

Answer:

∠ A = 30°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

90 + x + 67 + x + 37 = 180, that is

2x + 194 = 180 ( subtract 194 from both sides )

2x = - 14 ( divide both sides by 2 )

x = - 7

Then

∠ A = x + 37 = - 7 + 37 = 30°

5x + 2y = 20

6x + 5y = 24

Answers

Answer:

(4,0)

Step-by-step explanation:

Let's solve your system by elimination.

5x+2y=20;6x+5y=24

Multiply the first equation by 5,and multiply the second equation by -2.

5(5x+2y=20)

−2(6x+5y=24)

Becomes:

25x+10y=100

−12x − 10y = −48

Add these equations to eliminate y:

13x = 52

Then solve13x=52for x:

13x=52

(Divide both sides by 13)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

5x+2y=20

Substitute 4 for x in 5x + 2y = 20:

(5)(4)+2y=20

2y+20=20 (Simplify both sides of the equation)

2y+20+ −20 = 20 + −20 (Add -20 to both sides)

2y = 0

(Divide both sides by 2)

y=0

Victoria and Javier are collecting aluminum for a community service project. Victoria previously collected 56 pounds and is collecting at a rate of 8 pounds per hour this weekend. Javier collected 16 pounds earlier and Is now collecting at a rate of 12 pounds per hour. How many hours must pass (x) before the two students have collected the same amount of aluminum (y)?​

Answers

Answer:

10 hours

Step-by-step explanation:

Victoria collects:

8x + 56

Javier collects:

12x + 16

They get same amount:

8x + 56 = 12x + 1612x - 8x = 56 - 164x = 40x = 10

Angles 1 and 2 are supplementary. If angle 1 measures (2x +2)°, and angle 2 measures (x - 5)° what is the measure of each angle?

Answers

Answer:

angle 1 is = 124 angle 2 is = 56

Step-by-step explanation:

supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.
