Answer:
D. 3 1/2
Step-by-step explanation:
Sum means addition (+)
Sum of a number, x and 1/2=4
This means the addition of the two numbers
x+1/2=4
Make x the subject of formula
x=4-1/2
Finding the L.C.M
= 8-1/2
x=7/2
x=3 1/2
Y=x-v\b
if that's all your information then that's the answer
The answer is D. 50 because x equals 7 so if you fill that in for 4x-3 and multiply it by 2, you get 50
Answer:

Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are
number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is
=6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is
. (Answer)
Answer: y = x^2 - 2 does not represent a linear function because the squared exponent above the variable makes that equation quadratic. Quadratic equations look like parabolas on a graph, rather than lines.
