If you're looking for the " $decimal$ " then your result will be $0.5$
because we had to divide the $numerator$ from the $denominator$

But, if you're trying to find what is " $equivalent$ " then your answer would be $\frac{1}{2}$ because, we had to divide the number $3$ since it goes into both numbers (if that makes since to you)

$Anyhow!$

Good luck on your assignment and enjoy your day!

Simplify and express the answer as a decimal. 3(2.7+5)−2 Enter your answer in the box.

First, add 2.7 and 5 to get 7.7. Then, multiply 7.7 and 3 to get 23.1. Finally, subtract 2 from 23.1.

If you're distributing, then multiply 3 by 2.7 and 5. Then, add and subtract the sum by 2.

Hope this helped!

Find all pairs of real numbers $(x,y)$ such that $x + y = 6$ and $x^2 + y^2 = 28$. if you find more than one pair, then list you

vivado [14]

1. $x^2+y^2=28$ and x+y=6

2. x^2+y^2 and x+y remind us of the formula: $(x+y)^{2}= x^2+y^2+2xy$

substituting we get:

$6^{2}= 28+2xy$

2xy=36-28
xy=8/2=4

3 Let's solve the system of equations i)x+y=6 and ii)xy=4

substitute y=4/x in (i):

$x+ \frac{4}{x} =6$

multiply all sides by x:

$x^{2} +4=6x$

$x^{2} -6x+4=0$

complete the square:

$x^{2} -6x+4=x^{2} -2*3x+9-9+4= (x-3)^{2}-5=0$

$x-3=\sqrt{5}$ or $x-3=-\sqrt{5}$

$x=3+\sqrt{5}$ or $x=3-\sqrt{5}$

so from x+y=6, y=6-x

case 1, $x=3+\sqrt{5}$ gives $y=3-\sqrt{5}$

case 2, $x=3-\sqrt{5}$ gives $y=3+\sqrt{5}$

Answer:

$(3-\sqrt{5}, 3+\sqrt{5})$ , $(3+\sqrt{5}, 3-\sqrt{5})$

Give me a good explanation please! I don't really understand what to do when exponents aren't the same xD

nevsk [136]

$(5*10^{-7} )*(3*10^{6} ) = (5*3) *(10^{-7} *10^{6} ) = 15*(10^{(-7) + 6} ) = 15 * 10^{-1} =0.15*10^{1}$

Hope that helps!

The perimeter of a rectangle is 34 units. Its width is 6.56, point, 5 units.

kifflom [539]

Answer: equation for length 34- (6.5 times 2) that whole thing divided by 2

Step-by-step explanation:

You know the width and a rectangle has 2 PAIRS of equal sides so if you know the width you just have to multiply that by 2 [ to account 4 the other side with the same length] and subtract that from the perimeter! Then you divide that answer by 2 to get what one side's length is!

hope that helped if it was not helpful sorry because i am a first grader :/
