(2.5, 1.3, 2.2, x), mean = 1.8
AleksAgata [21]

Answer:

<em><u>please mark me a brainliest</u></em>

\frac{2.5 + 1.3 + 2.2 + x}{4}  = 1.8

\frac{6 + x}{4}  = 1.8

6 + X = 1.8 * 4

6 + X = 7.2

X = 7.2 - 6

X = 1.2

So therefore the value of X is 1.2

26=4v+3v+12 can anyone help?
motikmotik

Answer:

Step-by-step explanation:

Combine like terms

3v + 4v

26=7v+12

Subtract    12  from both sides of the equation

26-12

12-12

14=7v

Simplify

so subtract the 12's

Divide both sides of the equation by the same term

14 divided by 7

7 divided by 7

Simplify

do the division and move the term on the other side and it would be

v=2

Solution

 

v=2
