X-20 = Y+20........ X-Y = 20+20........
X-Y = 40
AND
2Y-44=X+22............. Y-X= 44+22
Y-X=66
NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....
X-Y =40
Y-X= 66
IF WE COLLECT ....... 2Y = 106 AND Y = 53
THEN, USE Y IN ANY EQUATIONS FOR FINDING X
X-53 = 40 ..... X= 53+40 .......... X= 93
X= 93
Y=53
Hi there
The formula of the future value of annuity due is
Fv=pmt [(1+r)^(n)-1)÷r]×(1+r)
Fv future value?
PMT payment 9000
R interest rate 0.04
N time 75−51=24 years
So
Fv=9,000×((((1+0.04)^(24)−1)
÷(0.04))×(1+0.04))
=365,813.17
It's c
Hope it helps

Here's the solution ~
The given points are : (-7 , -4) and (1 , 1)
now, let's use distance formula to find the distance between them !





5/6 of the boys brought their lunch.
In order to determine the answer you need to divide 5/9 by 2/3 in which will give you 5/6.
