Answer:
2
degree is highest exponent in equation and 2x² has 2 and is highest
To determine the value of X in the given equation substitute the value of y into the equation and solve for x.
1/5x - 2/3y = 30
1/5x - 2/3(15) = 30
1/5x -10 = 30
1/5x - 10 + 10 = 30 + 10
1/5x = 40
1 = 5x • 40
1 = 200x
X = 1/200.
we know that
1 ft is equal to 12 in
step 1
dimensions of plywood required
(12+3+3) x (18+3+3)------> 18 in x 24 in
step 2
convert inches to feet
18 in-------> 18/12=1.5 ft
24 in------> 24/12=2 ft
step 3
area of plywood required
A=b*h------> 1.5*2------> A=3 ft²
the answer is
3 ft²
Total percentages of student who scored As
= 25+35= 60%
Probability of a girl who got A = 35/60
If you simplify the ans will be 7/12
The system is comprised of two processes
that go on at the same time:
#1). Do what ever you want to, to get 'x'
on one side of the equation, and
everything else on the other side.
#2). Whatever you do to one side of the equation,
you must immediately do the same thing to the
other side.
That's the system.
Here's how it works: (I can't believe you're in high school math
and you've never seen, studied, or practiced this before.)
You said that 4x - 9 = 2x + 15
and you need to find
what 'x' is.
Subtract 2x from each side: 2x - 9 = 15
Add 9 to each side: 2x = 24
Divide each side by 2 : x = 12 .
