The sum of three consecutive even numbers is 78. What is the first number
Answers
(2,4,6, example)
so they are
n,n+2,n+4
their sum is 78
n+n+2+n+4=78
3n+6=78
minus 6
3n=72
divide 3
n=24
smallest is 24
3x = 75
x = 25
So the three numbers are 25, 26, and 27.

5x/7=22
multiply by 7 both sides
5x=22*7-------> 5x=154
divide by 5 both sides
x=154/5
x=30.8--------> x=30 4/5
the answer is
x=30 4/5
The equation is solved and the mixed number is x = 30 4/5
Given data:
To solve the equation 5x/7 = 22, we need to isolate the variable x.
We can start by multiplying both sides of the equation by 7 to eliminate the fraction:
(5x/7) * 7 = 22 * 7
This simplifies to:
5x = 154
To solve for x, we can divide both sides of the equation by 5:
(5x)/5 = 154/5
x = 30.8
The solution as a mixed number is represented as:
x = 30.8 can be written as 30 and 4/5 in mixed number form.
Hence, the correct mixed number solution is x = 30 4/5.

3 + 7 = ?
To figure that you can just add in your head since its easy.
3 + 7 = 10
You can work backwords to check to see if your awnser is right.
When you work backwards you do the opposite of what you are doing, so if your adding the opposite would be subtracting, and if your multiplying than the opposite would be dividing.
So you could work it out like this:
(Regular⬇️)
3 + 7 = 10
(Backwards⬇️)
10 - 7 = 3
And if you get the same numbers that were in the original awnser than you are correct! Hope this helps!!!!

Answer:
x = 11, x = -11
Step-by-step explanation:
I know this is kind of late but the two previous answers were wrong.
We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:
√x² = √121
x = √121
You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.
Answer:
x=11
