Answer:

d3=13.125 miles

Step-by-step explanation:

Given data:

total distance = 21 miles

s1=8 miles/hr

s2=8 miles/hr

s3=10 miles/hr

First we have to find out the how much time it takes when Supria and Elle meet.

As we know,

Displacement=rate*time

d1=s1*t

d2=s2*t

d1+d2=21

8t+8t=21

16t=21

t=21/16

Now we can find that how much the third friend had traveled during this time period

d3=s3*t

d3=10*21/16

d3=13.125 miles

So first we need to know this:

Two negative signs make a positive
Two positives make a positive
One positive and one negative makes a negative.

So we can turn the equation to -4 -44 - - 1
2 minuses make plus
-4 -44 +1 = -48 +1 = -47

Solve for x. Find the angle measures. Angle AOB=x+3, angle AOC=2x+11, angle BOC=4x-7
Ghella [55]

Answer:

x=5

AOB = 8

BOC = 13

AOC = 21

Step-by-step explanation:

<em>Angle AOB and Angle BOC is equal to Angle AOC.</em>

AOB = x+3

BOC = 4x-7

AOC= 2x+11

AOB + BOC = AOC

x+3+4x-7 = 2x+11

5x-4 = 2x+11

3x = 15

x = 5

Therefore, the value of x is 5.

<em>Angle AOB = x+3</em>

AOB = 5+3

AOB = 8

<em>Angle BOC = 4x-7</em>

BOC = 4(5)-7

BOC = 13

<em>Angle AOC = 2x+11</em>

AOC = 2(5)+11

AOC = 21
