Answer:

x= 8

Below is the diagram.

Step-by-step explanation:

Given,

YW \ bisects\ \angle XYZ

Such that,

m\angle XYW=\ m\angle WYZ

Thus, substituting their values.

(3x-7)=(2x+1)\\3x-7=2x+1\\3x-2x=1+7\\x=8

The davis family traveled 35 miles in 1/2 hour if it is currently 2:00pm any the family destination is 245 miles away at what ti
xxMikexx [17]

The distance traveled by Davis family = 35 miles

Time taken to cover the distance = \frac{1}{2} hour

Speed = Distance \div Time

Speed = 35 \div \frac{1}{2}

Speed = 35 \times 2

So, speed = 70 miles/hour.

At 2:00 pm, the family destination was 245 miles away.

So, the number of hours, when the family was 245 miles away = 245 \div 70

=  3.5 hours

So, after 3.5 hours,  that is at 5:30 pm, the Davis family will be 245 miles away.

Four friends were born in consecutive years. The sum of their ages is 94. What is the age of the oldest friend?
Savatey [412]
Hello,

We don't need algebra to solve this.

I suppose the ages are 1,2,3,4
Their sum is 1+2+3+4=10.
To obtain 94 we must add 94-10=84 for 4 persons =>84/4=21 to each

Ages are
1+21=22
2+21=23
3+21=24
4+21=25

But if really want an algebric resolution:

Let's x the age of the youngest
x+1,x+2,x+3 the others.

x+(x+1)+(x+2)+(x+3)=94
==>4x+6=94
==>4x=88
==>x=22
Ages are 22,23,24,25.

The oldest friend is 25 years old.
