Answer:
0,00027 grams!
Step-by-step explanation:
This is a scientific notation problem.
When a number is followed by a
, it means that said number has one zero at the beginning.
In this case, the number is followed by
, so that means that 2.7 has four zeros at the beginning. So, 2.7x
grams is equal to 0,00027 grams! (always the comma goes after the first zero).
<u>Answer:</u>

<u>Explanation:</u>
let the number be x, now we are given that four times the cube of a number which means four multiplied by the cube of number
i.e 4 multiplied by
is less than the difference of 40 and the number x i.e 40 - x
x is for sure less than 40 as
is less than the difference between 40 and x so if we write x - 40 then we will obtain negative value which will be greater than
.
So, the inequality obtained can be written as 
46 -2c
46 decreased by means 46 minus
Twice c would be c times 2
Answer:
A (a = 1)
Step-by-step explanation:
A coordinate point is always in the form (x,y) that means the first point is always x-coordinate and the second point is always y-coordinate.
The equation given is:
5x + y = 8
The point is (a,3), so that means x = a and y = 3
We substitute the values into the equation and find a. Shown below:
5x + y = 8
5(a) + (3) = 8
5a + 3 = 8
5a = 8 - 3
5a = 5
a = 5/5
a = 1
Answer choice A is right
