Answer:

f(u) = 9/5

Step-by-step explanation:

u - 5 = -4(u - 1) Distribute on the right side

u - 5 = -4u + 4

+4u +4u Add 4u to both sides

5u - 5 = 4

+ 5 + 5 Add 5 to both sides

5u = 9 Divide both sides by 5

u = 9/5

Answer: 1, 4

Step-by-step explanation:

Number #1 = x
Number #2 = $\frac{1}{4} x$

$\frac{1}{4} x+x=5\\\\\frac{1}{4} x+\frac{4}{4} x=5\\\\\frac{5}{4} x=5\\\\5x=4*5\\5x=20\\x=4$

Number #1 = x = 4
Number #2 = $\frac{1}{4} x$ = $\frac{1}{4} *4=\frac{4}{4} =1$

Solve the equation . (-2 1/7)p=-3

34kurt

Answer:

p = $\frac{7}{5}$

Step-by-step explanation:

change the mixed number to an improper fraction

- 2 $\frac{1}{7}$ = - $\frac{15}{7}$ , hence

- $\frac{15}{7}$ p = - 3 ( multiply both sides by 7 )

- 15p = - 21 ( divide both sides by - 15 )

p = $\frac{-21}{-15}$ = $\frac{7}{5}$
