Answer 1

Ответ:

а) 37*x=259

x=259/37

x=7

б) 252/y=21

y=252/21

y=12

в) z/18=6

z=18*6

z=108

г) (38+b)*12=840

38+b=840/12

38+b=70

b=70-38

b=32

д) 14*(p-30)=630

p-30=630/14

p-30=45

p=30+45

p=75

е) (43-s)*17=289

43-s=289/17

43-s=17

s=43-17

s=26

Answer 3

а) To solve the equation 37x = 259, we can divide both sides of the equation by 37:

37x = 259 x = 259 / 37 x ≈ 7

Therefore, the solution to the equation is x ≈ 7.

б) To solve the equation 252 / y = 21, we can multiply both sides of the equation by y:

252 / y = 21 252 = 21y

Now, divide both sides of the equation by 21:

252 / 21 = 21y / 21 12 = y

Therefore, the solution to the equation is y = 12.

в) To solve the equation z / 18 = 6, we can multiply both sides of the equation by 18:

z / 18 = 6 18z = 6 * 18 18z = 108

Now, divide both sides of the equation by 18:

18z / 18 = 108 / 18 z = 6

Therefore, the solution to the equation is z = 6.

г) To solve the equation (38 + b) * 12 = 840, we can divide both sides of the equation by 12:

(38 + b) * 12 = 840 38 + b = 840 / 12 38 + b = 70

Now, subtract 38 from both sides of the equation:

38 + b - 38 = 70 - 38 b = 32

Therefore, the solution to the equation is b = 32.

д) To solve the equation 14(p - 30) = 630, we can first distribute the 14 to both terms inside the parentheses:

14p - 14 * 30 = 630 14p - 420 = 630

Next, add 420 to both sides of the equation:

14p - 420 + 420 = 630 + 420 14p = 1050

Now, divide both sides of the equation by 14:

14p / 14 = 1050 / 14 p = 75

Therefore, the solution to the equation is p = 75.

е) To solve the equation (43 - s) * 17 = 289, we can divide both sides of the equation by 17:

(43 - s) * 17 = 289 43 - s = 289 / 17 43 - s = 17

Now, subtract 43 from both sides of the equation:

43 - s - 43 = 17 - 43 -s = -26

Multiply both sides of the equation by -1 to isolate s:

(-1)(-s) = (-1)(-26) s = 26

Therefore, the solution to the equation is s = 26.
