Answer:
x = 118
Step-by-step explanation:
1. All the angles in a pentagon add up to 540, so to find the value of x, we can use this equation x + 122 + 103 + 98 + 99 = 540.
2. (Solving)
Step One: Simplify both sides of the equation by adding like terms.
- (x) + (122 + 103 + 98 + 99) = 540
- x + 422 = 540
Step Two: Subtract 422 from both sides.
- x + 422 - 422 = 540 - 422
- x = 18
U should use friendly numbers when subtracting.......the numbers have to be between 3 and 10
The triangle is obtuse since the sum of the squares of 2 sides are greater than the square of the third side. (Converse Pythagorean theorem) Hope this helps!
Answer:
The annual income of A and B are in the ratio 3 : 4. If the income of A is 3x, the income of B is 4x. Their annual expenditure is in the ratio 5:7, if A's expenditure is 5y, B's expenditure is 7y. Each of them saves 15000 per month.
Step-by-step explanation:
=> 3x - 5y = 15000 and 4x - 7y = 15000
3x - 5y = 15000
=> y = (3x - 15000)/5
Substituting...
Answer: Y will increase in value.
Step-by-step explanation: Inverse basically means 'opposite'. So, whats the opposite of decreasing? Increasing!
