What is the solution to the system of equations?<br><br> x+y=5<br> x-2y=2<br><br> (_,_)
Nady [450]
You can use the substitution method. Using the first equation in terms of y,
y = 5 - x
Substitute this to the second equation to get the value of x.
x - 2(5 - x) = 2
x - 10 + 2x = 2
3x = 2 + 10
3x = 12
x = 4

For y, just substitute the value of x that we have used in the first equation.
y = 5 - 4 = 1

Therefore, in coordinate form, that is (4,1)

The length of a rectangle is 2 foot less than 3 times its width. Find the the dimensions of this rectangle if the area is 96 squ
Xelga [282]
For example,area = a, length = l, width = w
First we write two equations. The easier equation is the area equation, which we know to be
a = l x w
So that the first equation is : 
<span>96 = l x w </span>

we make the second equation of the following statements :
<em>The length of a rectangle is 2 foot less than 3 times its width.</em>
<span>so it becomes :
l = 3w - 2
</span>
<span>To solve, we can use the substitution method. 
</span>
96 = l \times w\\96=(3w-2) \times w\\96=3w^{2}-2w\\3w^{2}-2w-96=0~~~~~~[now\ factor\ the\ equation]\\ (3w+16)(w-6)=0

3w+16=0\\3w=-16\\w= -\frac{16}{3}~~~~\Rightarrow~~~answer\ doesnt\ make\ sense\ , negative\ width.&#10;

w-6=0\\\boxed{w=6~~~~~~~\Rightarrow~~~~positive\ answer\ for\ width\ makes\ sense }&#10;

<span><em>So if our width is 6, Now substitute the value of w = 6 into equation 2 </em></span>

l=3w-2\\l=3(6)-2\\l=18-2\\l=16

So "w" = 6 and "l" = 16, and if we multiply them together, we get the correct area, 96. So our dimensions are 6 by 16.

A bicycle is traveling at 16 miles per hour. How many feet will it cover in 35 seconds? Round your answer to the nearest tenth o
ch4aika [34]

A  bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.

It is required to find How many feet will it cover in 35 seconds.

<h3>What is conversion?</h3>

conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons. Units are used for measuring length, measuring weight, measuring capacity, measuring temperature, and measuring speed.

Given that:

1 hour = 60min×60sec = 3600 sec

1 miles = 5280 feet

16 miles = 16×5280ft = 84480 ft

3600sec ................. 84480  ft

35sec ................................ x ft

x = 35×84480/3600

=2956800 /3600

= 821.33 feet.

Hence, a bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.
