Answer:
The value of x = 110°
Step-by-step explanation:
=> x° + 90° + 90° + 70° = 360 ° { sum of angles of a quadrilateral is 360 }
=> x + 250° = 360°
=> x = 360 - 250
=> x = 110°
Answer:
$1500
Step-by-step explanation:
- Investment 1 = $3000
- Interest 1 = 4%
- Investment 2 = x
- Interest 2 = 5.5%
- Total interest = 4.5%
<u>Total interest:</u>
- 3000*0.04 + x*0.055 = (3000+ x)*0.045 ⇒ multiply by 100 both sides
- 3000*4 + 5.5x = 3000*4.5 + 4.5x ⇒ parenthesis
- 5.5x - 4.5x = 3000(4.5-4) ⇒ collect like terms
- x = 3000*0.5 ⇒ simplify
- x = 1500 ⇒ answer
Additional money is $1500
