Evaluate the expression, using the given value of the variable.
3 – 7x + 2x when x = 3
A.–18
B–30
C.–24
D.–12

the answer is C, -24

Step-by-step explanation:

3-21+6= -24

Hy buddy we have to solve the given problem and find the value of x

so let us solve

Step-by-step explanation:

the equation is = 3-7x+2x

and value of x is given as 3

x = 3

so let us put the value of x in the ewuation written above

3-7x+2x

= 3-5x

putting x as 3

= 3 - 5×3

= 3 - 15

= -12

answer: the answer is 5/22

step-by-step explanation: if you subtract 17 from 22 the answer is 5 therefore the remainder of students are female

(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
