so don't know the equation but it's 15 months. a year and 3 months.
Step-by-step explanation:
so first able, he already has 150 in his saving account. he adds 25$ every month after hai bday. a year has 12 months in which one of them is his birthday. so the rest 11 months he adds 25$. 25×11=275 then 150+275=425 so he needs 75 more dollars to have 500$ 25+25+25=75 so there fore we have 3 more months. so that means that a year and three months. sorry if you didn't understand I'm bad at explaining
H represents the number of hours: -13+5h=12 5h=12+13 (add 13 to both sides) 5h=25 h=25÷5 (divide both sides by 5) h=5 After 5 hours the temperature will be 12°F. If it was 4 a.m. 5 hours ago then now it's 9 a.m. (4+5=9) Hope this helped.
