X + y = 56 ------------------(1)
x:y = 5:3
x/y = 5/3
3 x = 5 y
so, x = (5/3)y---------------(2)
sub (2) in (1)
x + y = 56
(5/3)y + y = 56
5 y + 3 y = 168
  8 y  = 168
  y  =  168 / 8  = 21
x = (5/3) x 21
  =  35
the value of x - y = 35 - 21
                          = 14

Solve and graph each of the following inequalities for x.
Ulleksa [173]

2x + 4 > 8

Step 1: Subtract 4 from both sides.

2x + 4 − 4 > 8 − 4

2x > 4

Step 2: Divide both sides by 2.

2x/2  >  4/2

x > 2

2x − 3 < 5

Step 1: Add 3 to both sides.

2x − 3 + 3 < 5 + 3

2x < 8

Step 2: Divide both sides by 2.

2x/2  <  8/2

x < 4

Please I’m desperate and tell me how you did it
777dan777 [17]

Given:

Triangle EFG is similar to triangle HIJ.

To find:

The measure of side IJ.

Solution:

We know that, corresponding sides of similar triangles are proportional.

Triangle EFG is similar to triangle HIJ.

\dfrac{EF}{HI}=\dfrac{FG}{IJ}

Putting the given values, we get

\dfrac{7}{32}=\dfrac{4}{IJ}

7\times IJ=4\times 32

IJ=\dfrac{128}{7}

IJ=18.2857

IJ\approx =18.3

Therefore, the measure of side IJ is 18.3 units.

Draw a division model to show how many 1/4 are in 3 1/2
Rina8888 [55]
First, you would need to create an equation for this problem.
3 \frac{1}{2} ÷ \frac{1}{4}

Next, you would flip the second fraction and change it to multiplication.
3  \frac{1}{2} × \frac{4}{1}

Now, you would change the first fraction into an improper fraction and cross simplify the equation. 
\frac{7}{2} × \frac{4}{1}
\frac{7}{1} × \frac{2}{1}

Finally, you would solve it. 
\frac{7}{1} × \frac{2}{1} = \frac{14}{1} = 14

3 \frac{1}{2} ÷ \frac{1}{4} = 14

I hope this helps!
