Hallie used a birthday check her mother gave hero to start a savings account. She plans to save $25 per month as well. After 9 months Hallie has 300. Write and solve a linear equation to find original check from Hallie's mother.

$75

Step-by-step explanation:

x+(25×9)=300

x+225=300

x=300-225

x=$75

step-by-step explanation:

d

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
