Answer:
<em><u>x=2, y=4</u></em> (as a point,) (2, 4) (last part is unnecessary unless you are graphing)
Step-by-step explanation:
Use substitution.
Substitute y for 2x.
Since y=2x, you can plug 2x into the place where y goes...
Instead of y=-1/2x+5
2x=-1/2x+5....Now solve
2.5x=5 (Sorry my computer cannot type fractions very clearly)
/2.5 /2.5 (dividing by 2.5 on both sides)
<u><em>x=2</em></u>
Now just plug x into any of the equations to find y (preferably the easier one).
y=2x becomes
y=2*(2)
=4
<em><u>y=4</u></em>
Answer:
2-120
4-240
7-420
Step-by-step explanation:
<em>there are 60 people in each tour group so you multiply 60 by the number of tour groups.</em>
ordered pairs:
<em>(2,120)</em>
<em>(4,240)</em>
<em>(7,420)</em>
hope this helped you!
have a great day!!
Answer:
18, 22
Step-by-step explanation:
Half of 40 is 20 right? Then one number has to be 2 less, while the other number is 2 more. So there is a difference of 4.
