Equivalent form of the first equation that eliminates x when added to the second
To do this, we simply make the coefficients of x to be opposite in both equations.
In the second equation, the coefficient of x is 8.
So, we need to make the coefficient of x -8, in the first equation.
Multiply by -10
![-10 * [\frac{4}{5} x-\frac{3}{5}y=18]](https://tex.z-dn.net/?f=-10%20%2A%20%5B%5Cfrac%7B4%7D%7B5%7D%20x-%5Cfrac%7B3%7D%7B5%7Dy%3D18%5D)
<em>When this is added to the first equation, the x terms becomes eliminated</em>
The answer would be $14.75. You would have to do .59 times 25 bananas and you would would get $14.75.
A is the right answer i think
triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle
a^2 + b^2 = hypotenuse squared
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 =
18.5
add up the areas of the 2 triangles and rectangle
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the
square root of 702.25 which is
26.5
to get the perimeter
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
1 + 1= 2
2 + 2 = 4
3 + 3 = 6
4 + 4 = 8
5 + 5 = 10
