Step-by-step explanation:

then let's transistors this into mathematical symbols :

9 times a number y

9×y or simply 9y

subtracted from 85

85 - ...

is seven times

= 7 × ...

the sum of four and y

(4 + y)

together this is then

85 - 9y = 7 × (4 + y)

and just FYI : let's solve this

85 - 9y = 7×4 + 7y = 28 + 7y

85 = 28 + 16y

57 = 16y

y = 57/16 = 3.5625

PLS HELP What is the quotient?

ryzh [129]

Answer:

Step-by-step explanation:

$2\frac{1}{5}dividedby\frac{-1}{10}=2\frac{1}{5}*\frac{-10}{1}\\\\=\frac{11}{5}*\frac{-10}{1}\\\\=11*-2=-22\\$

Keep the first fraction, change division to multiplication and find the reciprocal(multiplicative inverse) of the second fraction

$\frac{11}{50}dividedby\frac{11}{50}=\frac{11}{50}*\frac{50}{11}\\\\ =1$
