Answer:
x < 33.84
Step-by-step explanation:
we have
13.48x-200 < 256.12
Solve for x
Adds 200 both sides
13.48x-200 +200 < 256.12+200
13.48x < 456.12
Divide by 13.48 both sides
13.48x/13.48 < 456.12/13.48
x < 33.84
The solution is the interval ----> (-∞, 33.84)
All real numbers less than 33.84
Answer:
B. 6Fx + 6Gy = 6H
Qx + Ry = S
Step-by-step explanation:
Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.
_____
<em>Comments on other choices</em>
A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.
B: the correct choice
C: see A.
D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.
Answer:
c) infinite
Step-by-step explanation:
z - y = 12
-3z + 3y = -36
<h3>
simplify the first equation to find z in terms of y</h3>
z - y = 12
<em>add 12 to both sides of the equation</em>
z - y + y = 12 + y
z = 12 + y
<h3>now, substitute z for 12 + y in the second equation.</h3>
-3z + 3y = - 36
-3(12 + y) + 3y = -36
-36 -3y + 3y = -36
-36 = - 36
the answer is infinite solutions, because no matter what y and z are, -36 will always equal -36
