What is -31+-4x=-5+-5(1+5x)

Mathematics
1 answer:
aliya0001 [1]3 years ago
5 0

Answer:

x=1

Step-by-step explanation:

-31+(-4x) = -5+(-5)(1+5x)

-31-4x = -5+(-5)+(-25x)   : Adding a negative is the same as subtracting and I distributed the -5

-31 = -5 + -5 -21x    : added 4x to both sides

-31 = -10 -21x       : added -5 and -5

-21 = -21x           : added 10 to both sides

x=1   : divided both sides by -21, division of 2 negatives is a positive

If G is the incenter of ∆ABC, then GD = GF = GE.

Given, GD is 3x + 5 and GF is 6x - 4.

According to the above statement,

GD = GF

or, 3x + 5 = 6x - 4

or, 5 + 4 = 6x - 3x

or, 9 = 3x

or, 9/3 = x

or, 3 = x

The value of x is 3.

By putting the value of x in GD or GF, we get

GD = 3(3) + 5 = 9 + 5 = 14

GF = 6(3) - 4 = 18 - 4 = 14

Therefore, GE = <u>14</u>.

at the start of the shift your part counter reads 250 at the end of the shift the part counter reads 1075 how many parts did you
Luden [163]
This can be mathematically expressed to
 250 + X  = 1075
where X represents the parts you produce before the shift ends
Transpose 250 to the other side by subtracting each side by 250
Thus, it goes like this
X = 1075 - 250
X = 825

You produced 825 parts in the middle of the shift.
