Answer: See below
Step-by-step explanation:
Isolate x for x-2y+2z=9
3x=9+2y
....(1)
Substitute (1) into the 2nd equation
7y=-3
y=-3/7
Substitute y=-3/7
Isolate z by substituting it
For x =9+2y/3 substitute z=59/21 and y=-3/7
Answer:
A. Figure A
Step-by-step explanation:
The protractor on the top left has an arrow halfway inbetween 50° and 60, making the angle 55°.
Therefore, the answer is Figure A.
I'm guessing you want to know how much is in one case,
36/3 = 12
Answer:
f(x)= 1.38x
y= 1.38x
Step-by-step explanation:
basically the cost= 1.38 per pound
you can use cost=1.38x if ur grade level isn't at f(x) yet
<3
5 units over
with a scale factor of .5
What this is asking is how do you turn the one shape into the other. The first answer is how many spaces apart they are. In this case the smaller rectangle EHGF was 5 units (or squares over... Also note that the fact that the larger rectangle is higher doesn't matter because the space is reduced when it is shrunk). The second answer was talking about how much smaller it was. This is identified by counting the sides. rectangle EHGF had sides 1 unit (square) and 2.5 units (squares) long this is half or .5 of the larger ABCD's 2 units (squares) and 5 units (squares).
