Answer:
country a = 19,812 cars
country b = 6,604 cars
Step-by-step explanation:
a = country a
b = country b
the 2 eqations are:
a + b = 26,416
a = 3b
now substitute 3b for a in the first equation:
3b + b = 26,416
add the variables:
4b = 26,416
now divide 26,416 by 4 (26,416/4)
b = 6,604
so country b has 6,604 cars
to find country b, substitute the number of cars in country b (which is 6,604) in the second equation:
a = 3b
a = 3 × 6,604
a = 19,812
so country a has 19,812 cars
Answer:
Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
Step-by-step explanation:
If we work out this particular equation according to the acronym PEMDAS
(or parenthesis, exponents, multiplication, division, addition, subtraction) this can be easily done. The resulting equation would look
as follows PEMDAS2(3)2+16(2)+112+112+1=13
