Here all you have to do is draw and put in what is given then cross multiply.
I have attached a picture to show you how to.Good Luck :)
Answer:
D. y = –x
Step-by-step explanation:
2 = - (-2)
- 3 = - (3)
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
Answer: 0.92 feet (choice B)
You're close but not quite there. To get the answer, you divide 29.44 over 32
If you had 32 feet of banner and 32 students, then each student would get 32/32 = 1 foot. Since the length of the banner is smaller than the number of students, this means each student only gets a fraction of a foot. This fraction value is fairly close to 1 because 29.44 is close to 32.
