juan and adam both need pens and batteries. The equation that represents Juan's purchases is y= 27 -3x. The equation that represents Adam's purchases is y = 17 - x. if x represents the price of the batteries, and y represents the price of the pens, what are the price of the pens snd batteries. Please if you answer this explain it!
Answer:
pens are 12
batteries are 5
Step-by-step explanation:
y=27-3x y=17-x
-17 +3x 27-3x=17-x -17 +3x
2x=10
x=5
y=27-3x y=27-3(5) y=27-15
y=12

Find the measure of the missing angles.
X=
Y=
Z=
Answer:
X= 41
Y= 90
Z= 41
Step-by-step explanation:
X=Z
Y+49=139
Z+Y+49=180
X+139=180
139+49+X+Z+Y=180
These we know because of the placement of the angles.
Using this information, we can solve this in numerous ways. I'm going to solve it using one of them. Making both sides equal to 180 and then checking my work by adding all of the numbers I get together to make sure that they equal 360.
X+139=180
X=41
X=Z.
49+Z+Y=180
49+41+Y=180
90+Y=180
Y=90
Thus,
X= 41
Y= 90
Z= 41
To check, let's add them all together.
41+90+41+139+49=
360
This is correct!
