Answer:

x=15

Step-by-step explanation:

The given equation is

-2x+4=-\frac{1}{3}x-21

Here the variable is x and the terms with the variable are -2x \;and\; -\frac{1}{3}x.

Keep all the terms having variable on one side and all the constants terms on the other side as

-2x+\frac{1}{3}x=-21 -4

Now, simplify the above equation to get the value of x as

-\frac{5}{3}x=-25 \\\\\Rightarrow \frac{5}{3}x=25 \\\\\Rightarrow x=\frac{25\times3}{5} \\\\\Rightarrow x=15  \\\\

In this way, the value of x is 15.

This problem involves the addition of integers. When we add up a positive number and a negative number, it results in subtraction. The final answer will have a sign the same as the higher number.

In this problem, the negative number has a higher value than the positive number, hence, the final answer is a negative number. Doing the operation, we get

1+(-2)=-1

Answer: -1

Inessa05 [86]

Answer: Probability that the next donation is not a pair of gloves is 0.54.

Step-by-step explanation:

Since we have given that

Number of coats = 5

Number of pairs of gloves = 23

Number of scarves = 19

Number of hats = 3

Total number of winter clothing is given by

5+23+19+3=50

Probability that the next donation is not a pair of gloves is given by

Not gloves = 50-23=27

P(not gloves ) is given by

=\frac{Not\ gloves}{total}\\\\=\frac{27}{50}\\\\=0.54

Hence, Probability that the next donation is not a pair of gloves is 0.54.
