Jeremy wrote this equivalent equation to solve for x: x = negative 11 y minus 140 Which of these equations might have been Jeremy's original equation? Check all that apply. y + 7x = 23 y + 11x = 140 2x – 22y = –140 3x + 33y = –420 x + 140 = –11y

3x+33y= -420

x+140= -11y

Step-by-step explanation:

x= -11y-140

y +7x=23

7x=23-y

x=23/7 - y/7

y+11x=140

11x=140-y

x=140/11 - y/11

2x-22y=-140

2x=-140+22y

x=-140/2+22y/2

x=-70+11y

3x+33y=-420

3x=-420-33y

x=-420/3 - 33y/3

=-140-11y

x=-140-11y

x+140=-11y

x=-11y-140

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
