Answer:
Solution for 2x-10=16 equation:
2x - 10 = 16
2x = 16 + 10
2x = 26 (divide both sides by 2 to get x)
2x/2 = 26/2
x = 13
Step-by-step explanation:
Answer:
Area = 78.5
Step-by-step explanation:
31.4 = 2 x pi X r
r = 31.4/(2xpi) = 31.4(2 x 3.14) = 5
Area = pi x r^2 = 3.14 X 5^2 =3.14 x 25 = 78.5 units^2
First write an equation for this (with X being the dads age).
X/4 +2= 13
Solve for x to find the dads age.
X/4=11
X=44
His dad is 44 years old
Four times the sum of a number and 6.
work:
the 4 is multiplying the expression in parenthesis, so we can start with
4 times.
in the parenthesis, a number n is being added to 6.
we are multiplying this by 4, so it's 4 times the sum of a number plus six. hope this helps! :D
