Answer:

12 m

Step-by-step explanation:

The area of a rectangle is length•width:

  • length=<em>x</em>
  • width=3\frac{2}{3}
  • area=44

We can set up an equation and solve for <em>x</em>:

  • <em>x</em>•3\frac{2}{3}=44
  • Divide– <em>x</em>=44/3\frac{2}{3}
  • Make improper fraction– <em>x</em>=44/\frac{11}{3}
  • Same, change, reciprocal– <em>x</em>=44•3/11
  • Multiply– <em>x</em>=12

Hcf of two numbers is 2 and lcm is 54 if one of the number is 27 find the other number
anyanavicka [17]

Answer:

4

Step-by-step explanation:

Given that:

Let the two numbers = a and b

H. C. F of the two numbers = 2

L.C.M of the two numbers = 54

If a = 27 ; b =?

The product of a and b = product of their L. C. M and H. C. F ;

HENCE ;

27 * b = 2 * 54

27b = 108

b = 108/27

b = 4

Hence, second number is 4

3+6×5+4÷2-7 using the same expression,add parentheses so that the value of the expression is 38​
solmaris [256]

Answer:

3+6×(5+4÷2)-7  

Step-by-step explanation:

To solve the expression use order of operations.

Right now the expression solves to:

3+6×5+4÷2-7                  6* 5 = 30

3 + 30 + 4÷2-7                4 ÷ 2 = 2

3 + 30 + 2 - 7                   Add and subtract left to right.

33 + 2 - 7

35 - 7

28

To make it solve to 38, add parenthesis:

3+6×(5+4÷2)-7                (5+4÷2) = 7

3+6×(7)-7                        6*7 = 42

3 + 42 - 7                        Add and subtract from left to right

45 - 7

38
