3p-4=8
+4 on both sides to get
3p=12
divide each side by 3 to get p=4

2p=4
divide off 2 on both sides to get
p=2

Is 2=4? If it is then it is equivelent, if it isnt then theyre not.

In your class 11 out of 25 students have brown hair. What percent have color other than brown? Show work..

Vinvika [58]

You can work this out two ways:

1) you can find the percentage of students who have brown hair, and subtract from 100% to find the total percentage of other hair colors,

11 / 25 = 0.44 or 44% > 100% - 44% = 56% < this is the number of students without brown hair,

or

2) you can find out the number of students who have a different hair color, and finding the percentage of that new number:

25 - 11 = 14 < this is the number of students in the class that have a hair color other than brown. To find the percentage:

14 / 25 = 0.56 or 56%

Answer: 56% of students do NOT have brown hair.

3. Segment MN has endpoints at M(-6, -3) and N(9,7). Point Q lies on MN such that MQ:QN = 3:2.

Aleks04 [339]

Given:

Segment MN has endpoints at M(-6, -3) and N(9,7).

Point Q lies on MN such that MQ:QN = 3:2.

To find:

The coordinates of point Q.

Solution:

Section formula: If a point divides of line segment whose end points are $(x_1,y_1)$ and $(x_2,y_2)$ in m:n, then the coordinates of that points are:
