Answer:
17
Step-by-step explanation:
To find the number of green beads that Felicia used, we first need to list out what we know.
Let x = number of green beads.
Yellow Beads = 153
So we get:
x*9 = 153
We divide both sides by nine to find the value of x.
x = 17
To see if we got the answer correct, let's substitute x.
x * 9 = 153
17 * 9 = 153
153 = 153
Answer:
3 Shirts
Step-by-step explanation:
$68-$32=$36
$36/$12= 3
Step-by-step explanation:
I guess method 1 means to deal with whole factors.
x + 5 = (x - 2)(x + 5)
for (x + 5) <> 0 we can divide both sides by this factor :
1 = x - 2
x = 3
for the second solution we deal with
x + 5 = 0
x = -5
so, for x = -5 and x = 3 both functions deliver the same output, and these are the intersection points.
method 2 : we multiply the expression out and solve it then
x + 5 = (x - 2)(x + 5)
x + 5 = x² + 5x - 2x - 10 = x² + 3x - 10
0 = x² + 2x - 15
the general solution to such a square equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 2
c = -15
x = (-2 ± sqrt(2² - 4×1×-15))/(2×1) =
= (-2 ± sqrt(4 + 60))/2 = (-2 ± sqrt(64))/2 = (-2 ± 8)/2 =
= -1 ± 4
x1 = -1 + 4 = 3
x2 = -1 - 4 = -5
and you get the 2 solutions again. as expected, they are the same as with method 1, of course.
Set up a triangle with the ladder being the hypotenuse the wall being one side and the distance away being the other side. Now use pythagorean theorem a^2+b^2=c^2
4^2+15^2=c^2
16+225=c^2
241=c^2
C=15.52 now round
C=15.5 feet
