Answer:

85/36

Step-by-step explanation:

  1. Add the numbers 5 and 4. This gives us 9. so now our equation is 4x(9)=85
  2. Multiply 4x by 9. This gives us 36x. So now our equation is 36x=85.
  3. Since 36 is being multiplied by x, we must divide it on both sides. This leaves us with 85/36, which cant be simplified. Thus, our final answer is 85/36

Hope this helps

Answer:

x = (85/36) or 2.36111111111

Step-by-step explanation:

4x(5+4)=85

Distribute the 4x among the parenthesis.

4x(5) + 4x(4) = 85

Multiply the numbers.

20x + 16x = 85

Combine like terms.

36x = 85

Isolate the variable

(36x)/36 = 85/36

x = (85/36) or 2.36111111111

Hope it helps, have a nice day <3

GaryK [48]
For this case, the first thing we must do is define a variable.
 We have then:
 x: number of muffin plates
 We now write the expression that models the problem.
 We know there are 4 muffins in each dish, therefore, we have:
 4x&#10;
 Substituting for x = 0 we have:
 4 (0) = 0&#10;
 Answer:

Melanie and Michael are on the north bank of a river that is flowing east to west at a speed of 0.5 m/s. They paddle their surf
IRINA_888 [86]

Answer:

total distance travel by them to cross river is 17.3 m

Step-by-step explanation:

Assume A be the initial position of both person and B as apposite point to A

u  component of velocity along SOUTH DIRECTION is 4 cos30 = 0.4330 m/s

v  component of velocity along SOUTH DIRECTION is 4 cos90 = 0 m/s

total speed will be = 0.4330 + 0  = 0.4330 m/s

time taken= \frac{width/ of/ river}{speed}

time taken = \frac{30}{0.4330} = 69.3 sec

component of u in downstream direction = 4 cos120 = -0.25 m/s

component of v in downstream direction = 4 cos 0 = 0.5 m/s

total component in downstream will be -0.25 + 0.5 = 0.25

total distance travel by them to cross river is = 0.25\times 69.3 = 17.3 mdownstream.
