<em><u>The equation with no fractions is:</u></em>

30x + 80 = 36

<em><u>Solution:</u></em>

<em><u>Given that the equation is:</u></em>

\frac{3}{4}x+2=\frac{9}{10}

We have to rewrite the equation such that there is no fraction

From given expression,

\frac{3}{4}x+2=\frac{9}{10}

Simplify the left hand side of equation

\frac{3x+8}{4} = \frac{9}{10}

Cross multiply to get a simpler equation

10(3x+8) = 9 \times 4\\\\Simplify\ the\ above\ expression\\\\30x + 80 = 36

Thus the equation is rewritten with no fractions

Inessa [10]
X is  the number of dog
y is the number of cats , y=40
25% of x is  25*x /100=25x/100=x/4
<span>and there are 25% more cats than dogs means y+ x/4=x implies 40=(3/4)x
</span>x=160/3=53
so the number of dogs is 53 and the number of cats is 40
the total number is 53+40=93

How to solve this system of equal: x+y+z=1;x^2+y^2+z^2=1
swat32

There are infinitely many solutions.

Algebraically, we can eliminate z and try to solve for x,y:

x+y+z=1\implies z=1-x-y

Then

x^2+y^2+(1-x-y)^2=1

\implies x^2+y^2+1-2x+x^2-2y+y^2+2xy=1

\implies x^2-x+y^2-y+xy=0

which is the equation of an ellipse.

Nadia makes a monthly income of $4,000. How much will Nadia have for impulse shopping after she pays all of her bills for the mo
Llana [10]
You add all the percentages up and it will give you 64. take 64 and put it over 100 because percentages as a fraction will always be the amount over a 100.  
so its 64/100 multiply by 4000/1. 64*4000= 256000 over 100. 256000 divided by 100 = 2560

$2560
