Answer:
Combing like terms we get 13x + 48x = 61x and -19y + 43y = 24y so the answer is 61x + 24y.

Answer:
-40 °F = -40 °C
Step-by-step explanation:
(1) F = 1.8 C + 32
If the Fahrenheit and Celsius temperatures are the same, then
(2) F = C Substitute (2) into (1)
C = 1.8C + 32 Subtract 1.8 C from each side
C – 1.8 C = 32 Combine like terms
-0.8C = 32 Divide each side by -0.8
C = -32/0.8
(3) C = -40 Substitute (3) into (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
So, -40 °F = -40 °C
The thermometer below shows that -40 °F = -40 °C.
Answer:
Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are 
and 
.
The famous quadratic formula for solving any second order equation is the following:
Where a is the coefficient of 
, b is the coefficient of x, and c is the free term. In other words,
as the equation should be in the following form:
Therefore the possible answer should be the following,
by dividing the numerator and denominator by 2, we can deduce the following,
