<Q and <R are complementary angles. If m<Q = (31 - 3x)° and m<R = (19x - 5)°, find m<R

Amanda [17]

31-3x+19x-5=90

26+16x=90

-26 -26

--------------------

16x= 64

16x/16= 64/16

x=4

m <R=19 (4)-5= 71.

What is 12% of (3/4) of 1.8? Express as a decimal.

Crank

PLease note that in mathematics, "of" means multiplication. Thus, 12% of (3/4) of 1.8 can be rewritten as $(\frac{12}{100}) \times \frac{3}{4}\times 1.8$

Thus we have: $0.12 \times 0.75 \times 1.8$

Now, $0.12 \times 0.75 \times 1.8=0.162$

Therefore, 12% of (3/4) of 1.8 expressed as a decimal is 0.162.

Therefore, 0.162 is the correct answer.
