Karolina [17]

Answer:

Both of them will have the amount of money after 2 weeks and both of them have \$\: 150.

Step-by-step explanation:

Jayden has $100 and saves $25 per week.

Liv has $180 and spends $15 per week.

Let both of them have the same amount of money after x weeks.

According to the question,

\Rightarrow 100+25x=180-15x

\Rightarrow 25x+15x=180-100

\Rightarrow 40x=80

\Rightarrow x=\frac{80}{40}

\Rightarrow x=2

So, both of them will have the amount of money after 2 weeks.

After 2 weeks, Jason will have 100+25\times 2=100+50=150 dollars.

Hence, both of them will have the amount of money after 2 weeks and both of them have \$\: 150.

Please solve this question. cant understand
saul85 [17]

Answer:

x=150°

Step-by-step explanation:

A=180-60=120

B=180-60=120

C=45

D=360-120=240

E=45

The sum of the interiors of a polygon is (n-2)*180.  Since this is a hexagon, (6-2)*180=4*180=720. SO..

B=720-120-120-45-240-45=150

Assuming the questions is asking to solve for x, the angle is 150°
