Lillian and Jacob work at a dry cleaners ironing shirts. Lillian can iron 25 shirts per hour, and Jacob can iron 20 shirts per h

vladimir1956 [14]

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:

$\left \{ {{x+y=13} \atop {25x+20y=295}} \right. => \left \{ {{x=7} \atop {y=6}} \right.$

so Lillian worked 7h and Jacob worked 6h

CAN ANYBODY PLS HELP

Firdavs [7]

The correct options are

$5x = - 58 \:$ $5x + 4 = - 54$

<h3>How to find same value of x?</h3>

given that

$\frac{5}{6} x + \frac{2}{3} = - 9$

first find value of x to obtain the equations have the same value of x.

Find the L.C.M between the 6,3

$\frac{5x + 4}{6} = - 9$

Then Cross multiplication should be done

$5x + 4 = - 9 \times 6 \\ 5x + 4 = - 54 \\ 5x = - 54 - 4$

$5x = - 58$

Hence the correct options are

$5x = - 58$

$5x + 4 = - 54$
