Answer:
345.6
Step-by-step explanation:
Answer:
3a (2b-3c)
Step-by-step explanation:
9 (8- - 125)
should equal 1197
64+36=c^2
100=c^2
square root both sides for 10=c
10 is your answer
x = 3 + y Eqn(1)
y = -2x + 9 Eqn(2)
Let us solve the system of equations with the substitution method
x - 3 = y (Subtracting 3 from both sides of the Eqn(1))
Replacing y = x - 3 in Eqn (2), we have:
x - 3 = -2x + 9
x = -2x + 9 + 3 (Adding 3 to both sides of the equation)
x + 2x = 9 + 3 (Adding 2x to both sides of the equation)
3x = 12 ( Adding like terms)
x = 12/3 (Dividing by 3 on both sides of the equation)
x = 4
Replacing x=4 in Eqn(1), we have:
4 = 3 + y
4 - 3 = y (Subtracting 3 from both sides of the equation)
y=1
The answers are:
x= 4 and y=1
(h + j)(x)
h(x) + j(x)
2x - 3 + -4x
-2x - 3
