Answer:
Brett is 62 years old, Carl is 70 years old and Mark is 80 years old.
Step-by-step explanation:
let the age of Brett be <em>x</em> years.
thus the age of Mark is <em>(x+18)</em> years .
{as it is given that Brett is 18 years younger than Mark}
∴ Age of Carl is <em>(x+8) </em>years .
Now the sum of ages,
3x+26=212 (given)
3x=186
∴x=62
thus , the age of Brett is 62 years , the age of mark is <em>(x+18)</em>= 80 years and the age of Carl is <em>(x+8)</em>= 70 years
Answer:
0.5 or 1/2
Step-by-step explanation: Use the slope formula: y2 - y1 / x2 - x1
0 - (-2) / -5 - (-9)
2 / 4
= 0.5 or 1/2
Answer:
106.5 square units.
Step-by-step explanation:
See the attached diagram.
The pentagon ABCDE consists of three triangles namely Δ ABC, Δ ACD, and Δ ADE when we join the diagonals AC and AD.
So, Area of Pentagon ABCDE = Area of Δ ABC + Area of Δ ACD + Area of triangle Δ ADE.
⇒ Area of Pentagon ABCDE = (31.8 + 39.2 + 35.5) = 106.5 square units. (Answer)
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 3 and (a, b) = (2, -
) , thus
y - (-
) = 3(x - 2) , that is
y +
= 3(x - 2) → C
