Question

упражнение номер 4. Ооочень срочно!!!

Answer 1

1) 360+х:3=440х:3=440-360х:3=80х=80×3х=240
2) x\8+140=212x\8=212-140x\8=72x=72*8x=576
3) (x+25)*4=360x+25=360/4x=90-25x=6565+25)*4=360360=360

Answer 2

a)
$360 + \dfrac{x}{3} = 440\\ \dfrac{x}{3} =80\\ x = 3\cdot 80\\ x=240$

б)
$\dfrac{x}{8} + 140 =212\\ \dfrac{x}{8} = 72\\ x = 8\cdot 72\\ x = 576$

в)
$(x+25)\cdot 4 = 360 \\ 4x + 100 = 360\\ 4x = 260\\ x = 65$
