Answer:Combine like terms

−

{\color{#c92786}{3x}}+5{\color{#c92786}{-x}}=9x-7+12

3x+5−x=9x−7+12

−

{\color{#c92786}{2x}}+5=9x-7+12

2x+5=9x−7+12

Add the numbers

Subtract the same term from both sides of the equation

Simplify

Subtract the same term from both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify

PLS HELP ASAP I WILL IVE BRAINLIST ANSWER!!!!!Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using thi

Juliette [100K]

Answer:

Leon is correct. (Option 1)

Step-by-step explanation:

Given that Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure.

Step 1: Find the greatest common factor of the given lengths: 7

Step 2: Divide the given lengths by the greatest common factor: 3, 4, 5

Step 3: Verify that the lengths found in step 2 form a Pythagorean triple.

we have to explain whether or not Leon is correct.

As, 3,4,5 forms a Pythagorean triplet i.e satisfies the Pythagoras theorem

$Hypotenuse^2=Base^2+Perpendicular^2$

⇒ $5^2=3^2+4^2$

Let a, b, c forms a Pythagorean triplet

$a^2+b^2=c^2$

Multiplied by 4 on both sides

⇒ $4a^2+4b^2=4c^2$

⇒ ${2a}^2+{2b}^2={2c}^2$

Hence, we say 4a, 4b and 4c also forms a Pythagorean triplet.

∴ multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

Hence, Leon is correct.

317,362 x 129,324<br> Is it even or odd

Anna35 [415]

Answer:

41,042,523,288 It is even.

Step-by-step explanation:

To tell whether a number is even or odd, look at the number in the ones place. That single number will tell you whether the entire number is odd or even. An even number ends in 0, 2, 4, 6, or 8. An odd number ends in 1, 3, 5, 7, or 9.

I need help !! I’m stuck on this question

Nataliya [291]

Answer: D. a+2s=$22

a+3s=$28

Step-by-step explanation:

Let's take a look at our variables. They are a and s, the a standing for the cost of an adult ticket and the s standing for the cost of the student ticket. In both situations, only one adutl ticket was purchased, so we start off out equations with only an a. As for the student tickets, Alex buys 2 and Jen buys 3.

a+2s

a+3s

The whole point of writing this equation is to find the cost of the tickets, so we would both equal it to the amount they spent.

a+2s=$22

a+3s=$28
