Answer 1

Answer:

a) 75

b) 360 students

c) 56 ; 57 ; 58

d) 134 inches

e) 27°

Step-by-step explanation:

a)

$5x = 375 \\ x = \frac{375}{5} \\ x = 75$

b)

$\frac{x}{3} = 120 \\ x = 120 \times 3 \\ x = 360$

c)

$x + x + 1 + x + 2 = 171 \\ 3x = 168 \\ x = 56 \\ (x + 1 = 57) \\ (x + 2 = 58)$

d)

$2x + 2 \times 70 = 408 \\ 2x = 408 - 140 \\ x = \frac{268}{2} \\ x = 134$

e)

$180 = 90 + 63 + x \\ x = 180 - 90 - 63 \\ x = 27$
