Ineed ! traslate the following sentences into mathematical expressions, equations, or inequalities.1) twice x increased by five is less than seven.2) three times the sum of a number y and two is eighteen.3) the quotient of six and a number is added to the square root of x.4) eleven less than four times a number.5) 3-x3=15

1) 2x=5<7

2) 3(y+2)=18

3) 6x+√x

4)11<4x

5) the sum of three minus a number times three is 15

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
