Jenny has saved $3,800 over the last 12 months. she saved either $250 or $350 a month. during the 12 month period, how many times did jenny save $250 for the month?

Jenny save 4 times for the month

Step-by-step explanation:

Given Jenny has saved over the last 12 months.

She saved either or a month.

Let the number of months to save be x

Let the number of months to save be y

Total period is 12 month.

Jenny has saved $3,800 over the last 12 months.

Dividing both side from 50 we get,

Now Multiplying  equation 1 by 5 we get,

Now Subtracting Equation 3 by equation 2 we get,

Substituting the value of y in equation 1 we get,

∴ Jenny save 4 Months of   and 8 Months of  in a 12 month duration

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
