13x + 13 + 2x = 2
15x + 13 = 2
15x = -11
Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h
23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified
24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values
.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.
Total miles:350+150=500
Total hours:4+3=7
Avg speed:500/7=71.429 mph
Answer:
The answer to your questions radius = 14 in
Step-by-step explanation:
Data
Circumference = 28π in
radius = ?
Circumference is defined as the distance around the edge of a circle.
Formula
Circumference = 2π radius
-Solve for radius
radius = Circumference /2π
-Substitution
radius = 28π / 2π
-Simplification
radius = 28/2
-Result
radius = 14 in
hopefully this helps you and gives you insight in how to solve the problems from now on (:
= $11.8 + (2012-1997)([$11.8-$7.4][1997-1990])
= $11.8 + 5 ($4.4/7)
= $11.8 4/5 + $22/7
= $59/5 + $22/7
= $413/35 + $110/35
= $523/35 or $14 33/35
answer : SALES IN 2012 WOULD BE $14 33/35 BILLION OR $14.9 3/7
