Ok like what kind of math problems
Answer:
C.
Step-by-step explanation:
So there are 20 kids with brown hair and this represents 80% of the class total.
So this means 20=.8n since we don't know the total number of kids.
20=.8n
Divide both sides by .8
25=n
So 25 is the total number of kids.
C. is the answer
You could also setup this equation given that 80% is 80/100:
[tex]\frac{20}{\text{ total }}=\frac{80}{100}
To figure out what that total is there you can divide top and bottom of the fraction on right hand side by 4 which gives you the 20 on top and the 25 on bottom.
Okay
We have
slope(m)=-2/5
Point (0,-7)
For this question we use point slope form so
y − y1 = m(x − x1)
y=y coordinate of second point
y1=y coordinate of point one
M=slope
X=x coordinate of second point
x1=x coordinate of point one
By substituting each number to the corresponding variables we get
Y-(-7)=-2/5(x-0)
Y+7=-2/5x
Y=-2/5x-7 equation of required line!
Answer:
Step-by-step explanation:
1. The slope is 12
2. (6 - 2)/(12+4)= 4/16= 1/4
y - 2 = 1/4(x + 4)
y - 2 = 1/4x + 1
y = 1/4x + 3
