To solve, make an equation. The equation would be
x represents the miles driven
to solve, subtract 4 from each side of the equation.
$32-4 = 4-4 + 2x
The equation is now
$28 = 2x
Now you divide by 2 on each side.
$28 ÷ 2 = 2x ÷ 2
simplify
14 = x
The answer is 14 miles
11/15 + 7 ⇒ rational ⇒ the sum of two rationals is always rational
√14+13 ⇒ irrational ⇒ the sum of a rational and an irrational is always irrational
30×√6 ⇒ irrational ⇒ the product of a nonzero rational and an irrational is always irrational
11/12 × 7/15 ⇒ rational ⇒ the product of two rationals is always rational
Ok, if you say so. Jean took 1/2 hour to complete 3/8 of a math problem.
There's really no such thing as the value of a triangle.
Every triangle has three sides, three angles, a base, a height, and an area,
and there could be problems that ask us to find any one of those.
Whatever we need to find, the process is always the same:
-- Take the information that's given.
-- Gather up everything you can remember that talks about a relationship
between what you're given and what you need to find.
-- Use them together to find the missing value.
5x-5=4x+10
x=15
75-5=70
180-70=110
6y-4=110
6y=114
y=19
