Answer:
x = 3.8 + 53.6
Step-by-step explanation:
From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!
Answer: The giraffe is 1.5 times tall as the zookeeper.
Step-by-step explanation:
Given: Height of Giraffe =
Height of zookeeper=
Let <em>n</em> = number of times the giraffe is tall as the zookeeper.
Hence, the giraffe is 1.5 times tall as the zookeeper.
To factor this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?).
The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6.
x - 3 = 0
x = 3
x + 2 = 0
x = -2
The two solutions are therefore, x = 3 and x = -2.
Answer:
f(n) = 4 +n
Step-by-step explanation:
We assume you want a function that tells the total number of tiles in figure N.
There are 4 triangular tiles in each figure. The number of square tiles is equal to the figure number (n). So, the total number of tiles in figure n is ...
f(n) = 4 +n
0.5x + 1/5y -3.5x - 4/5 y
0.5x - 3.5x + 1/5 y - 4/5 y. Regroup f/ variable
-3.0x - 3/5 y
