zaharov [31]

Given : A box of toffies can be divided among 24 and children each will get 4 .

To Find : Number of toffies will each get if the number of children is reduced 24

Solution : If toffies are distributed among the children and each child gets 4 , then the total number of toffies will be equal to , 24 × 4 = 96 toffies .

Again it is given that the toffies are redistributed among 24 children . So the number of toffies each will get will be equal to ,

=\bf \cancel{\dfrac{96}{24}}

=\Large\boxed{\red{\bf 4 }}

Complete the solution of the equation. find the value of y when x equals 4 -3x +9y = -57
Kazeer [188]

Answer:

y = -5

Step-by-step explanation:

-3x +9y = -57

Let x = 4

-3*4 +9y = -57

-12 +9y = -57

Add 12 to each side

-12+12 +9y = -57+12

9y = -45

Divide each side by 9

9y/9 = -45/9

y = -5

A computer printer can print a 660-word document in 35 seconds. At this rate, how many seconds are required to print a document
lesya [120]

Set up a proportion:


\frac{660}{35} = \frac{840}{x}


The numerator represents the words in the document, and the denominator represents the seconds it takes to print the document.


You can simplify the first fraction to make multiplication easier. Divide both the numerator and denominator by 5:


\frac{660}{35} \div \frac{5}{5} = \frac{132}{7}


\frac{132}{7} = \frac{840}{x}


Cross multiply both fractions:


132x = (840 \times 7) = 5880


Divide both sides by 132 to get x by itself:


5880 \div 132 = 44.54


\boxed{x = 44.54}


It will take 44.54 seconds to print the 840-word document.
