Answer:
It takes 2712 days.
Step-by-step explanation:
If it takes Mars to revolve around the sun 678 earth days, that means you will have to multiply that number by 4 (because the question is, "how many earth days does it take mars to revolve around the sun four times.")
Answer: 9/(3n)
Step-by-step explanation:
divided by means division and that would go on top of the fraction bar. The product indicates mulitiplcation, so a number can be represented as X.
Answer:
x = 2
Step-by-step explanation:
0.3 (4 - x) = x - 1.4
1.2 - 0.3x = x - 1.4
-0.3x - x = -1.4 - 1.2
-1.3x = -2.6
x = 2
Answer:
The value of x is 4 .
Step-by-step explanation:
Given as :
The two triangle is as
Let The smaller triangle = DEC
Let The larger triangle = ABC
The measure of side EC = a
The measure of side BC = x
∵ side BC = side EC (as both sides of triangle are equal)
So, x = a + a
i.e x = 2 a
From the figure shown it is clear that both triangles are similar
So, the ratio of triangles are equal
i.e =
or, =
Or, =
Or, 3 x - 5 = 7
Or, 3 x = 7 + 5
Or, 3 x = 12
∴ x =
i.e x = 4
Hence, The value of x is 4 . Answer
