Answer:
Section A = $27,000Section B = $14,800Section C = $12,200
Step-by-step explanation:
AC is perpendicular to BD
so
3x + 9 = 90
3x = 81
x = 27
answer
x = 27
---------------------------------------
in case if you need to find y
2x + y = 90
2(27) + y = 90
54 + y = 90
y = 90 - 54
y = 36
Answer:
4
Step-by-step explanation:
3x-12=24
-12 to both sides
3x-12-12=24-12
3x=12
3x/3=12/3x
x=4
Answer:
Y=10x
(multiply 10 times the salamanders)
Step-by-step explanation:
a formula that can be used for this circumstance is a linear y=mx+b problem. for 1 salamander there are 10 frogs. so with this we can state that y=10x. whatever you plug into the x for the number of salamanders will give you the answer of how many frogs are in the pond. for example.
Y=10x
Y=10(3)
Y=30
30 frogs.
also because 10 is a nice number you can just multiply the number of salamanders times 10. 3*10=30
