Find the second of two consecutive even numbers whose sum is 798

1 answer:

7 0

To set up consecutive even integers you use x for the first integer and x + 2 for the second integer. You add 2 since you are going to the next EVEN instead of just the next integer. Now we set up an equation = 798 and solve.
x + x + 2 = 798
2x + 2 = 798
subtract -2 from both sides
2x = 796
divide by 2 on both sides
x = 398
x + 2 = 398 + 2 = 400
CHECK 398 + 400 = 798

Solve for x using the distributive property. 9(5 - x) = 81 x = [?]

Ilya [14]

Answer:

$\boxed {x = -4}$

Step-by-step explanation:

Solve for the value of $x$ :

$9(5 - x) = 81$

-Use Distributive Property:

$9(5 - x) = 81$

$45 - 9x = 81$

-Subtract $45$ to both sides:

$45 - 45 - 9x = 81 - 45$

$-9x = 36$

-Divide both sides by:

$\frac{-9x}{-9} = \frac{36}{-9}$

$\boxed {x = -4}$

So, the value of $x$ is $-4$ .

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we know that "Angle opposite to greater side is smaller or angle opposite to smaller side is larger".

So, ∠AOD is opposite to side 'AD' which is equal to 8.11

Similarly, ∠AOB is opposite to side 'AB' which is equal to 8.

So, ∠AOB>∠AOD

Hence, Option 'B' is correct.

Answer:

-2

Step-by-step explanation:

You make x= -3 then you insert it into the problem which is x= 2(-3)+4

2 times -3 is -6 which then you would get

Schach [20]

Answer:

This type of essay answer is pretty short.

You play out the equation and say what each part of the equation means. The vertex in this case, because it's a downward facing parabola, is the highest point on the graph. Now since they're kicking a ball, the vertex will be the highest point that the ball will go up to.

Hopefully this helps some. For full points you'll probably have to add a bit of padding and further explanation.
