Answer:

  • -18

Step-by-step explanation:

  • 2(4 - 1/3u) = - u + 2
  • 8 - 2/3u = - u + 2
  • u - 2/3u = 2 - 8
  • 1/3u = -6
  • u = -6*3
  • u = -18

\huge \boxed{\mathbb{QUESTION} \downarrow}

  • \sf2 \left( 4- \frac{ 1  }{ 3  }  u  \right)   =  -u+2

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\sf \: 2 \left( 4- \frac{ 1  }{ 3  }  u  \right)   =  -u+2

Use the distributive property to multiply 2 by \sf 4-\frac{1}{3}u.

\sf \: 8+2\left(-\frac{1}{3}\right)u=-u+2

Express \sf2\left(-\frac{1}{3}\right) as a single fraction.

\sf \: 8+\frac{2\left(-1\right)}{3}u=-u+2

Multiply 2 and -1 to get -2.

\sf \: 8+\frac{-2}{3}u=-u+2

Add u to both sides.

\sf \: 8-\frac{2}{3}u+u=2

Combine \sf-\frac{2}{3}u and u to get \sf\frac{1}{3}u.

\sf \: 8+\frac{1}{3}u=2

Subtract 8 from both sides.

\sf\frac{1}{3}u=2-8

Subtract 8 from 2 to get -6.

\sf\frac{1}{3}u=-6

Multiply both sides by 3, which is the reciprocal of 1/3.

\sf \: u=-6\times 3

Multiply -6 and 3 to get -18.

\boxed{  \boxed{\bf \: u=-18 }}

joe has a piggy bank with $8.90 split upon nickels, dimes, and quarters. The piggy bank contains 76 coins in all. The number of
kozerog [31]

Answer:

There are 38 dimes, 22 nickels and 16 quarters.

Step-by-step explanation:

Let n, d and q represent the # of nickels, dimes and quarters respectively.

Then n + d + q = 76

The value of a nickel is $0.05; that of a dime is $0.10, and that of a quarter is $0.25.

Thus, the value of n nickels is $0.05n (and so on).

The total value of the coins is $0.05n + $0.10d + $0.25q = $8.90.

d = n + q allows us to eliminate d.

First, n + d + q = 76 becomes n + (n + q) + q = 76, and second:

$0.05n + $0.10(n + q) + $0.25q = $8.90.  Here we have succeeded in eliminating d from two different equations, and now we have these two different equations in two unknowns (n and q), which is solvable.

Simplifying both equations, we get:

2n + 2q = 76 and

5n + 10n + 10q + 25q = 890, or 15n + 35q = 890

Let's use the substitution method of solving linear equations:

Rewrite 2n  + 2q = 76 as n + q = 38, or n = 38 - q.  Substituting this result into the second equation, we get:

15(38 - q) + 35 q = 890, or

  570 - 15q + 35q = 890, or

   570 + 20 q = 890.  Then 20q = 890 - 570 = 320, and q = 320/20 = 16.

There are 16 quarters.  Thus, the number of nickels is n = 38 - 16 = 22.

Finally, since n + d + q = 76, 22 + d + 16 = 76, or:

22 + d = 60, or d = 60 - 22 = 38.

There are 38 dimes, 22 nickels and 16 quarters.

What is the percent decrease from 60 to 39?
IrinaK [193]
X - the percent decrease

60-60x=39 \ \ \ |-60 \\
-60x=-21 \ \ \ |\div (-60) \\
x=\frac{-21}{-60} \\ \Downarrow \\ x=\frac{-21}{-60}=\frac{-21 \div (-3)}{-60 \div (-3)}=\frac{7}{20}=\frac{7 \times 5}{20 \times 5}=\frac{35}{100}=35\%

It's a 35% decrease.
