Answer:

=2,133 3/7cm^2

Step-by-step explanation:

sides

15x16=240

240x2

=480cm^2

24×16=384

384×2= 768cm^2

768+480

a=1248cm^2

24x15=360cm^2

22/7x4x4

=50 2/7cm^2

360- 50 2/7

=354 5/7cm^2

(354 5/7)2

b=709 3/7cm^2

22/7x8x7

=22x8

c=176cm^2

a+b+c

1248+709 3/7+ 176

=2,133 3/7cm^2

NISA [10]

Answer:

x < -3/2

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

x + 2/3 < -5/6

Step 2: Subtract 2/3 from both sides.

x + 2/3 − 2/3 < -5/6 − 2/3

x < -3/2

In a discount clothing store, all sweaters are sold at one fixed price and all shirts are sold at another fixed price. If one sw
AfilCa [17]

Answer:

1 Sweater = <em>$</em><em>1</em><em>2</em>

1 Shirt = <em>$</em><em>1</em><em>0</em>

1st.

Sw = y

Sh = x

2nd: <em>set</em><em> </em><em>the</em><em> </em><em>problem</em><em> </em><em>into</em><em> </em><em>a</em><em> </em><em>function</em><em>. </em>

<em>-</em><em> </em><em>One</em><em> </em><em>sweater and four shirts cost $52</em><em>.</em>

y+x+x+x+x = $52

and

- Four sweaters and five shirts cost $98.

y+y+y+y+x+x+x+x+x = $98

3rd.

y+x+x+x+x = $52

y = 52-x-x-x-x

y = 52-4x

4th. <em>if</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>5</em><em>2</em><em>-4x</em><em>,</em><em> </em><em>we</em><em> </em><em>will</em><em> </em><em>substitute</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>second</em><em> </em><em>equation</em><em>. </em>

y+y+y+y+x+x+x+x+x = $98

52-4x+52-4x+52-4x+52-4x+5x = 98

208-16x+5x = 98

-16x+5x = 98-208

-11x = -110

x = -110/-11

x = 10

5th. if <em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>0</em><em>,</em><em> </em>now that we know what x equals to, we will substitute on the first equation to find out what y equals to.

y = 52-4x

y = 52-(4)(10)

y = 12

----------,-----------,---------,-----------,--------,--------,---------

Sweater = $12

Shirt = $10
