Answer:
Lillian worked 7h and Jacob worked 6h
Step-by-step explanation:
the number of hours Lillian worked are x (h)
the number of hours Jacob worked are y (h)
(0 < x,y < 13)
=> Lilian ironed: 25x (shirts)
Jacob ỉroned: 20y (shirts)
because Lillian and Jacob worked a combined 13 hours and ironed 295 shirts, we have:

so Lillian worked 7h and Jacob worked 6h
Answer:
25x^2 -1
Step-by-step explanation:
If you multiply parentheses:
(5x*5x) + (5x*-1) + (1*5x) + (1*-1)
25x^2 - 5x + 5x -1
25x^2 -1
A simpler way is to memorize this formula
(Square1 - square2)= (sqrt of square1- sqrt of square2)*(sqrt of square1 + sqrt of sqaure2)
Answer:
62.2x=y
Step-by-step explanation:
cost/ticket (c)
5000c = 311000
c = $62.20
Answer: 56 degree
Step-by-Step Explanation:
Let measure of unknown angle be ‘x’
One angle = 68 degree
Sum of all angles is 180 => 68 + 2x = 180
Therefore,
68 + 2x = 180
2x = 180 - 68
2x = 112
x = 112/2
=> x = 56
Therefore, the measure of the missing angles is 56 degrees each.
