X= 270
simplify the equation using cross multiplication
Answer:
112 dimes and a nickel.
because, one, 110 dimes equals 11.00 (so add the2 extra dimes.)
two, the .05 is a nickel not a .5 dime.
So that's your answer. 112 dimes and 1 nickel.
Area of a circle is PI x r^2, where r is the radius ( half the diameter).
Set up the equation to solve for r:
40 = PI x r^2
r^2 = 40/PI
r = SQRT(40/PI)
r = sqrt(40/3.14)
r = sqrt(12.74)
r = 3.57
Diameter = 2 x 3.57
Diameter = 7.14 feet.
Answer:
x = 3.9
Step-by-step explanation:
x/1.5 = 2.6
Multiply both sides by 1.5
x/1.5 × 1.5 = 2.6 × 1.5
x = 3.9
