A bird flies 61/2 mi in 20 min.

Mathematics
1 answer:
schepotkina [342]4 years ago
8 0

\frac{61/2}{20} =  \frac{x}{81/8}
multiply the 2nd fraction by 8/8 to get rid of the 8 in the denominator:
\frac{61/2}{20} = \frac{8x}{81}
simplify the 1st fraction by multiplying by 2/2:
\frac{61}{40} = \frac{8x}{81}
now, you can cross-multiply: 
61*81=40*8x
4941=320x
x=\frac{4941}{320} or 15 \frac{141}{320}

Solve for ppp. -5\left(p+\dfrac35\right) = -4−5(p+ 5 3 ​ )=−4minus, 5, left parenthesis, p, plus, start fraction, 3, divided by,
Angelina_Jolie [31]

Answer:

p = 1

Step-by-step explanation:

4 - 5(p + 3/5) = -4

Find P

4 - 5(p + 3/5) = -4

4 - 5p -15/5 = -4

4 - 5p - 3 = -4

-5p + 1 = -4

-5p = -4 - 1

-5p = -5

p = -5/-5

p = 1

Check:

4 - 5(p + 3/5) = -4

4 - 5(1 + 3/5) = -4

4 - 5 - 15/5 = -4

4 - 5 - 3 = -4

4 - 8 = -4

-4 = -4
