Answer:

The solution of inequality as x>-\frac{5}{4}

Step-by-step explanation:

 Given inequality 0.2(x + 20) – 3 > –7 – 6.2x

We have to solve the given inequality

Consider 0.2(x + 20) – 3 > –7 – 6.2x

Multiply both side by 10, we have

0.2\left(x+20\right)\cdot \:10-3\cdot \:10>-7\cdot \:10-6.2x\cdot \:10

on simplifying, we get,

2\left(x+20\right)-30>-70-62x

Expand by multiplying 2 , we get,

2x+40-30>70-62x

2x+10>70-62x

Subtract 10 both side, we get,

2x+10-10>-70-62x-10

Simplify, we get,

2x>-62x-80

Add 62x both side, we get,

2x+62x>-62x-80+62x

Simplify , we get,

64x>-80

Divide both side by 64, we get,

\frac{64x}{64}>\frac{-80}{64}

Simplify , we get,

x>-\frac{5}{4}

Thus, the solution of inequality as x>-\frac{5}{4}

205 1/5 is your answer

Step-by-step explanation:

break down the 3-D figure

Find area of triangle A=1/2bh

=1/2(8 inch)(6   9/10inch)

=1/2(8 inch)(69/10 inch)

=138/5 square inch

then multiply two because you have 2 triangles

=138/5 (2)  

= 276/5 square inch

= 55 1/5 sq.in

Find area of rectangle

A = lw

=6 1/4 in (8 in)

= 25/4 (8 in.)

= 50 sq. in.

then multiply by 3 because of the three rectangles

= 50 sq. inch (3)

= 150 sq. in.

Add all together

55 1/5 sq. inch + 150 sq. inch = 205 1/5 sq. inch

s344n2d4d5 [400]

Regina can take yoga classes at community center as it would cost her less money.

Step-by-step explanation:

No. of classes per week = 2

Classes in 6 weeks = 2*6 = 12 classes

Cost of classes at community center = $72

Additional one time fee = $12

Total cost at community center = 72+12 = $84

Cost per class at local gym = $8

Cost of 12 classes = 12*8 = $96

Regina can take yoga classes at community center as it would cost her less money.
