To determine the value of the given algebraic expression above, we simply substitute the values of each variable to the variables in the expression and evaluate the expression. We do as follows:
6x(y^2)(z)
when x = 0.5
y = -1
z = 2
6(0.5)((-1)^2)(2)
3(1)(2)
6
The value of the algebraic expression would be 6. An algebraic expression consists of variables which are represented with letters like for this case x, y and z, a coefficient which is indicated by numbers (e.g. 6 ) and exponents like 2 for the expression above. Often times expressions contains a number of terms which consists of those elements.

Step-by-step explanation:
Remark
It is really hard to tell what the playground is. Is he running around 45 yards plus the circumference of part of the circle? Or is just the triangle? Since pi is mentioned, I'll take it to be 45 + part of the circumference, but the ambiguity makes it possible to be wrong.
Equation
Distance = 2* (280/360) * pi * r + 45
Givens
r = 35 yards
Solve
C = 2 * 3.14 * (280/360) * 35 + 45
C = 2 * 3.14 * (0.77777777) * 35 + 45
C = 6.28 * 35 * 0.777777 + 45
C = 170.9555556
Answer
C = the distance for 1 lap around the playground. David went around 3 times.
3*C = 3 * 170.95555556
3C = 512.8666667
The distance he went is 513 yards <<<< Answer
X=13/15. Subtract 8x from both sides to get 3x=13/5. Divide both sides by 3 or multiple both sides by 1/3 to get x=13/15.
