Solve for X then Solve for angles 7X-40 and 2X+60

X = 20

Angles are both equal to 100 degrees

Step-by-step explanation:

Assuming that 7x-40 = 2x +60

1. Order of Operations

2. 5x = 100

3. divide 100 by 5

4. x = 20

5. Plug 20 into both equations

6. 7(20) - 40 = 100

   2(20) + 60 = 100

7. Both angles are equal to 100 degrees

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
