Viktor [21]
X = shorter piece
y = longer piece = 5x

shorter piece + longer piece = 60
x + 5x = 60
6x = 60
x = 60/6
x = 10  in. <== shorter piece

y = 5x
y = 5(10)
y = 50 in. <== longer piece

Find the solution set to each inequality. Express the solution in set notation.
daser333 [38]

The solution to the inequality 6m + 2 > -27 is  m > -4.33

The solution to the inequality 8(p-6)>4(p-4) is  p > 8

The given inequality is:

6m  +  2  >  - 27

Subtract 2 to both sides of the inequality

6m  +  2 - 2  >  -27  -  2

6m   >  -29

Divide both sides by 6

\frac{6m}{6}> \frac{-29}{6}  \\m  > \frac{-29}{6}\\m > -4.83

For the inequality  8(p-6)>4(p-4)

Expand the inequality using the distributive rule

8p  -  48   >  4p  -  16

Collect like terms

8p  -  4p  >  -16  +  48

4p    >  32

Divide both sides of the inequality 4

\frac{4p}{4} > \frac{32}{4}\\p > 8

The solution to the inequality 6m + 2 > -27 is m > -4.33

The solution to the inequality 8(p-6)>4(p-4) is p > 8

Find the area of the shape shown below.
sveticcg [70]

Answer:

A = 15u²

Step-by-step explanation:

Area of a Trapezoid Formula:

\frac{h}{2}*(b_1+b_2)

Plug in our values (h = 3, b1 =  7, b2 = 3)

\frac{3}{2}*(7+3)

Now we evaluate

\frac{3}{2}*(10)

\frac{30}{2} = 15
