Carlos is five years older than twice his sister's age. carlos is 13.which equation and solution correctly identifies his sister 's age?2x - 5 = 13; x = 92x 5 = 13; x = 42x - 5 = 13; x = 42x 5 = 13; x = 9
2 answers:
C=carlo=13 x=sister carlos (13) is (=) 5 years older (5+) twice sisters age (2 times x) 13=5+2x mius 5 both sides 13-5=5-5+2x 8=0+2x 8=2x divide both sides by 2 4=x 2x+5=13 x=4
Answer:
x=4
Step-by-step explanation:
Carlos is five years older than twice his sister's age. carlos is 13.
Let x represents the sister's age
Carlos age = twice of sisters age plus 5 years
twice of sister's age means 2 times sister's age
Carlos age =
Now Carlos age is 13
So the equation is
Now we solve for x to find the solution
Subtract 5 from both sides
Divide both sides by 2

A, because parallelogram is the same as a rectangle, just tilted a bit. therefore the method is just base X height.
A = 1/4 * (pi) * d^2 A = 1/4 * (pi) * 8^2 A = 1/4 * (pi) * 64 A = 1/4(64) * (pi) A = 64/4 * (pi) A = 16 (pi) in^2
Your answer is 16 pi in^2 ~Silver
