Answer:
<em>x</em><em>=</em><em>3</em><em>.</em><em>5</em><em> </em><em>y</em><em>=</em><em>8</em>
Step-by-step explanation:
Remeber, in a rectangle, opposite sides are equal so

and
a

Subsitue 2x+1 for y.





Plug this back in to one of the equations to find y.




So x=3.5
y=8
Answer:
It took 8 seconds for the leaf to reach the ground.
Step-by-step explanation:
The height of the leaf in feet can be found using the function:
y = -3.5*x + 28
where x is the time in seconds the leaf has been in the air.
You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:
0= -3.5*x + 28
and solving you get:
-28= -3.5*x
(-28)÷ (-3.5)=x
8=x

Answer:
Banners: 4
Paper lanters: 3
Bags of Balloons: 6
Garlands: 11
Step-by-step explanation:
Banner: 4*5.25= $21
Paper lantern: 6.50*x=?
Balloons: 5*x=?
Garland: 3.50*x=?
Paper lantern: 145.50/6.50= $22.3
22.3/6.50= 3.4 round to 3
3 paper lanterns
Balloons: 145.50/5= $29.1
29.1/5= 5.8 round to 6
6 packs of balloons
Garland: 145.50/3.50= $41.5
41.5/10= 4.15
4.15+7=11.15 round to 11
11 garlands
