Answer:

No

Step-by-step explanation:

Formula is a squared + b squared = c squared

12 times 12 = 144

7 times 7 = 49

144 + 49 = 193

so 15 times 15 should = 193

but 15 times 15 = 225

Answer:

This triangle is not a right triangle

Step-by-step explanation:

If it were a right triangle, then the pythagorean theorum would work

a^2 + b^2 = c^2

12^2 + 7^2 = 15^2

144 + 49 = 225

This is not true because 144+49=193, not 225

So this triangle is not a right triangle

Ryan and miles are each saving money. Ryan starts with $150 in his savings account and adds $40 per week. Miles starts with $50
m_a_m_a [10]

Answer:

The answer to your question is 5 weeks

Step-by-step explanation:

Data

Ryan                                      Miles

$150                                      $50

each week = $40                  each week = $60

x = savings

y = time in weeks

Process

1.- Write an equation for Ryan savings

     x = 40y + 150

2.- Write an equation for Miles savings

    x = 60y + 50

3.- Solve the system by Equality

          40y + 150 = 60y + 50

- Solve for y

          40y - 60y = 50 - 150

                   -20y = -100

                         y = -100 / -20

                         y =  5

4.- Conclusion

After 5 weeks, they will have the same amount of money.
