Answer:
x = (z + 3y) / 20
Step-by-step explanation:
20x - 3y = z
+3y +3y
-----------------------
20x = z + 3y
/20 /20
-----------------------
x = (z + 3y) / 20
Answer:
Hi there!
Your answer is:
The length is 75
Step-by-step explanation:
P=180
L=5w
Perimeter formula
L+L+W+W=P
Plug in known values
5W+5W+W+W=180
12W=180
/12
W=15
Plug in width in length formula!
L=5W
L=5(15)
L=75
Answer:
y = 40
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
y+10 + 2y +50 = 180
3y+60 = 180
Subtract 60 from each side
3y+60-60 = 180-60
3y = 120
Divide each side by 3
3y/3 = 120/3
y = 40
I believe it’s B
I’m kinda positive
Answer:
A) 16
Step-by-step explanation:
g= green apple
c= cinnamon
s= spearmint
74=g+c+s
g=2s
g-6=c
so we can replace c in the equation
74=g+g-6+s (because c=g-6)
we can also replace g in the equation
2s+2s-6+s=74 (because g=2s)
so, 5s-6=74 (add 6 to both sides)
5s=80 (divide by 5)
s=16
