20% also equals 1/5, right?
So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.
15 x 5 = 75
There were 75 total nests
Since both are equivalent to y, the equations must be equivalent.
x^2-x-3= -3x+5
x^2+2x-8=0
(x+4)(x-2)=0
x=-4, x=2
Plug the values of x in to either equation
y=-3(-4)+5
y= 12+5
y=17
y= -3(2)+5
y=-6+5
y=-1
Final answer: (-4,17) and (2,-1)
Answer:
3 : 50
Step-by-step explanation:
6% = 0.06
0.06 = 6/100
6/100 = 3/50
3/50 = 3 : 50
First, you want to get x by itself on one side. We write the equation as
. Since 14 is being subtracted from
, we add it to both sides to cancel it out,
or
.
Your answer would be D.
Answer:
m∠5 = 67
m∠7 = 67
Step-by-step explanation:
m∠4 and m∠5 add up to 180 because they are same side interior angles.
180 - 113 = m∠5
m∠5 = 67
m∠5 = m∠7 because they are vertically opposite angles
hence, m∠7 = 67 degrees
