If 2x=4(5-2x), then x=

NNADVOKAT [17]

x would equal 2 because:

4 times 5 is 20

4 times 2x is -8x

move over the 8x to the side with the 2x

then you have 10x=20

20/10 equals x=2

Hope this helps :)

Suppose you have 13 tubes of paint. How many distinct color groupings can you make with your paint?

anzhelika [568]

Answer:

32767 distinct color grouping

Step-by-step explanation:

Given data:

Total tube is 13

for distinct color, group can be 1,2,3,4,.... 15

For total number of ways we have following relation

$^nC_0 +^nC_1 +^nC_2 + .......^nC_n = 2^n$

here n = 13 so we have

$^15C_0 +^15C_1 +^15C_2 + .......^15C_{15} = 2^15$

for at least one

$= 2^{15} - 1$

$= 32768 -1$

= 32767 distinct color grouping

Can someone help me please

Luden [163]

Answer:

Step-by-step explanation:

Subtract column by column from the left, that is

6x² - 3x² = 3x²

- 5x - (+ 8x) = - 5x - 8x = - 13x

3 - (- 4) = 3 + 4 = 7

result of subtraction = 3x² - 13x + 7 → C
