2 friends bake 14 cookies each, and your sister will bake 18.
So total cookies already assigned = 2 (14)+18
= 28 + 18 = 46
Remaining cookies you need to bake = 102 - 46 =56

y = -5x + 3
Substitute the value for y.
y =1
1 = -5x + 3
Now, solve for x.
1-3 = -5x + 3 Apply the inverse operation to both sides of the equation.
-3
1-3 is -2
-2 = -5x
-5x/-5 = -2/-5
x = 0.4

By what percentage does the population change each year?
Answers
Answer:
- 280
- function represent growth.
- 29 %
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 280(1.29)^t
To find initial population size we will take t = 0
P(0) = 280(1.29)^0
= 280(1)
= 280
To find that function represent growth or decay
P(1) = 280(1.29)^1
= 280(1.29)
= 361.2
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(361.2 - 280 / 280) * 100%
= 29 %
Answer:
280
function represent growth.
29 %

How many hours of overtime did
Martha work this pas week?
Answers
Martha worked approximately 8 hours of overtime during the past week.
Martha's regular hourly rate is $14.50, and she works a regular forty-hour work week. Her overtime pay is one-and-one-half times her regular hourly rate.
Let's break down Martha's earnings for the week:
Regular Earnings (for 40 hours): Regular Hourly Rate × Hours Worked
Regular Earnings = $14.50 × 40 = $580
Total Earnings (including overtime): $754
Overtime Earnings = Total Earnings - Regular Earnings
Overtime Earnings = $754 - $580 = $174
Since Martha's overtime pay is one-and-one-half times her regular hourly rate, we can set up an equation:
Overtime Earnings = Overtime Hourly Rate × Hours of Overtime Worked
Solving for Hours of Overtime Worked:
Hours of Overtime Worked = Overtime Earnings / Overtime Hourly Rate
Overtime Hourly Rate = 1.5 × Regular Hourly Rate
Overtime Hourly Rate = 1.5 × $14.50 = $21.75
Now, plug in the values:
Hours of Overtime Worked = $174 / $21.75 ≈ 8
Martha worked approximately 8 hours of overtime during the past week.
