Step-by-step explanation:
Subtract equation ( ii ) from equation ( i ) :
Remember that the sign of each term of the second expression changes i.e equation ( i ) now becomes -4x -3y = -20

The first one because 2% as a decimal I'd 0.2
Zero-Exponent Rule: a0 = 1, this says that anything raised to the zero power is 1. ... Negative Exponent Rule: , this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
Answer:
complementary angles, x=19
Step-by-step explanation:
since the two parts of the angle add up to 90, they are complementary angles.
you can find x by adding them and setting it equal to 90:
3x-2+2x-3 = 90
5x-5 = 90
5x = 95
x = 19
Answer:
13⁰
Step-by-step explanation:
