Answer:

x =20

Step-by-step explanation:

We can use similar triangles and proportions to solve.  Take the smaller triangle side on top and the larger triangle side on the bottom.

11                 10

---------- = --------------

11+121             10 +5x+10

Combine like terms

11                 10

---------- = --------------

132             5x+20

Using cross products

11*(5x+20) = 10*132

55x+220 = 1320

Subtract 220 from each side

55x+220-220 = 1320-220

55x = 1100

Divide by 55

55x/55= 1100/55

x =20

I need help finding the formula..
KiRa [710]
X=first week
y=second week
z=third week
t=fourth week

18 more one 2nd week than 1st
x+18=y
x=y-18

3rd week, 4 less than 2 times as second
z=2y-4

4th week, 92

ttal=382

x+y+z+t=382
sub waht we know
x=y-18
y=y
z=2y-4
t=92

y-18+y+2y-4+92=382
conbine line terms
4y+70=382
minus 70 boht sides
4y=312
divide both sides by 4
y=78
