ur soft tacos and two double deckers .write a system of equations that represents the lunch orders for dory an d memo use x to represented soft tacos an y to represent double deckers
$11.25= 3s+3d $10.00= 4s+2d first eliminate 1 variable, lets say d ,to do this we must cancel them out, to do this multiply the top by -2 and the bottom by 3 -2 ($11.25= 3s+3d) -$22.50= -6s-6d 3 ($10.00= 4s+2d) which becomes... $30.00=12s+6d then the -6d and the positive 6d cancel out and you are left with 1 variable after this add the remaining parts to get... $7.50=6s divide by 6, then put s back into one of your original equations and solve for d then you have found how much each item costs and are finished with the system of equations
L is the number of hours Landen spent at the beach. Mateo spent 15% less time. This means he spent 85% of it. So 0.85 times L. We can also calculate it by subtracting the difference between the two kids. - 15%. 15% is 0.15L or . We subtract by L-0.15L or as . This fraction can simplify to
