Answer: About 9.2

Step-by-step explanation:

  Since this is a right triangle, we can use the Pythagorean theorem. We are solving for the hypotenuse which is the "c" variable in the formula.

a² + b² = c²

7² + 6² = c²

7² + 6² = c²

49 + 36 = c²

85 = c²

\sqrt{85} = c

9.2 ≈ c

Move the number that is not next to the variable to the other side of the equation by using the opposite operation Divide by the
dusya [7]

Given:

The equation is

8x-1=-50

To find:

The value of x by separating the variable.

Solution:

We have,

8x-1=-50

Here, -1 is not next to the variable. So, move -1 to the other side of the equation by using the opposite operation. After moving -1 to the right side of the equation it will become +1.

8x=-50+1

8x=-49

Divide both sides by 8.

x=\dfrac{-49}{8}

Therefore, the value of x is \dfrac{-49}{8}.

zzz [600]

Answer:

18+10=28

Step-by-step explanation:

(3x2)+(1x3)=3x3; it means 6+3=9 and 2+2=4

(3x3)+(1x3)=3x4; it means 9+3=12 and 4+2=6

(3x4)+(1x3)=3x5; it means 12+3=15 and 6+2=8

(3x5)+(1x3)=3x6; it means 15+3=18 and 8+2=10 (total number is 28).
