Step-by-step explanation:

${:}\longrightarrow$ $\sf 3 (x+5)+2 (2x+3)=0$

${:}\longrightarrow$ $\sf 3x+15+4x+6=0$

${:}\longrightarrow$ $\sf 3x+4x+15+6=0$

${:}\longrightarrow$ $\sf 7x+21=0$

${:}\longrightarrow$ $\sf 7x=-21$

${:}\longrightarrow$ $\sf x={\dfrac {-21}{7}}$

${:}\longrightarrow$ $\sf x=-3$

$\maltese{\underline{\boxed{\bf {x=-3}}}}$

Suppose your business has a special checking account used just for paying the phone bill. The balance is $740.00 this month. Nex

sergejj [24]

740-707.60=32.40
707.60-675.20=32.40
675.20-642.80=32.40
so that means every month you are paying 32.40$ bill. to get how many months you can pay phonebills without depositing any more money devide the 740/32.40=22.83 but you can not pay bill for the 0.83 month so answer will be 22 months
