<span>Let x=the smaller part
Then 55-x=the larger part
Now we are told the following:
2(55-x)=5x+12 simplify
110-2x=5x+12 add 2x to and subtract 12 from each side
110-2x+2x-12=5x+2x+12-12 collect like terms
98=7x</span>
First off, we'll convert the mixed fractions to "improper", and proceed,
I only know the answer to number 4 and I believe that it is C
Answer:
112.5%
Step-by-step explanation:
90/80 = 1.125
1.125 * 100 = 112.5
Inorder to the line, choose 2 y-intercepts, for example y1=0 and y2=1, then substitute each of them in the equation.
for y1 = 0:
0 + 1 = -3/5x + 12/4
3/5x = 12/4 - 1
3/5x = 2
x1 = 10/3
A(10/3;0)
for y2 = 1
1 + 1 = -3/5x + 12/5
3/5x = 12/5 - 2
3/5x = 2/5
x2 = 2/3
B(2/3;1)
Place the two resulting points exactly on the plane, and match them, then prolong the line.
