Answer:
yes
Step-by-step explanation:
They both equal to one half, which makes them proportional
C+p=15
5c+7p=91
multiply 5 to 1st equation and subtract it from 2nd
multiply 5 to 1st equation to get
5c+5p=75
now subtract this from 2nd equation
thats 2p=16
so
p=8
now we find c from
c+p=15
c=7
Let x is the days and the y is the height of the plant.
Let the change between x and y is linear.
So, the relation between x and y will take the form ⇒ y = ax + b
where a and b are constants.
At x = 30 ⇒ y = 18 ⇒⇒⇒ ∴ 18 = 30 a + b → (1)
At x = 90 ⇒ y = 29 ⇒⇒⇒ ∴ 29 = 90 a + b → (2)
solve (1) and (2) to find a and b
subtract (1) from (2)
∴ 11 = 60 a ⇒⇒⇒ ∴ a = 11/60
substitute at (1) ⇒⇒⇒ ∴ b = 25/2 = 12.5
<u>So, the equation which represents the plants growth is</u>
<u>∴ y = (11/60) x + 12.5</u>
Same blasted thing
you can just use logic
in the question you see 3 numbers: 300, 4, and 62
the blank is 62
now simplify them for 2nd blank snce notheing else changed
2nd blank is 248
3rd blank is another simplification or 300-248 or 52
1st blank is 62
2nd blank is 248
3rd blan kis 52
If you mean the calculation of 77x11 then the answer is 847
