Hey there!

The answer is no because whenever you add or subtract fractions, you find the common denominator(the bottom of the fraction)

Corret way:
The common denominator is 15 (5*3)
Multiply numerator(top) and the denominator by 3
4/5*3*3= 12/15
Multiply numerator and the denominator by 5
1/3*5/5= 5/15
So the equation is now
12/15+5/15= 17/15 or 1 2/15

Hope this helps! :)

Figure A is a scale image of figure B. Figure A maps to figure B with a scale factor of 2 1/2. What is the value of x? PLEASE AN

tigry1 [53]

Answer:

$x = 2$

Step-by-step explanation:

Figure B = 2½ the size of figure A

One side of figure B is given as 5, therefore, 5 = 2½ of x in figure A.

Thus, $5 = 2\frac{1}{2}*x$

Solve for x

$5 = \frac{5}{2}*x$

$5*2 = \frac{5x}{2}*2$

$10 = 5x$

$\frac{10}{5} = \frac{5x}{5}$

$2 = x$

$x = 2$

Answer:

$\textbf{Hello!}$

$\Longrightarrow2^2+2z=0$

$\Longrightarrow x_{1,\:2}=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \:0}}{2\cdot \:1}$

$\Longrightarrow \sqrt{2^2-4\cdot \:1\cdot \:0}$

$\Longrightarrow =\sqrt{2^2-0}$

$\Longrightarrow =\sqrt{2^2}$

$\Longrightarrow=2$

$\Longrightarrow x_{1,\:2}=\frac{-2\pm \:2}{2\cdot \:1}$

$\Longrightarrow x_1=\frac{-2+2}{2\cdot \:1},\:x_2=\frac{-2-2}{2\cdot \:1}$

$\Longrightarrow\frac{-2+2}{2\cdot \:1}$

$\Longrightarrow =\frac{0}{2\cdot \:1}$

$\Longrightarrow =\frac{0}{2}$

$=0$

$\Longrightarrow\frac{-2-2}{2\cdot \:1}$

$\Longrightarrow =\frac{-4}{2\cdot \:1}$

$\Longrightarrow =\frac{-4}{2}$

$\Longrightarrow =-\frac{4}{2}$

$=-2$

$x=0,\:x=-2\Longleftarrow$
