For #7, one line should have the y-intercept of -2 and a slope of 2/3 and the other line's y-intercept is 1 and its slope should be -5.

In the image provided, the red line represents 2/3x - 2 and the blue line represents -5x + 1.

8) Organize the information you are given.

*Savannah is 24 years older than Ryan.

So, Ryan's age + 24 = Savannah's age.

*Sebastian is 5 times as old as Ryan.
So, Ryan's age × 5 = Sebastian's age.

*Savannah and Sebastian are twins. They have the same age.
So, Savannah's age = Sebastian's age

Let x represent Ryan's age.

Write the equation based on the information you are given.

x + 24 = x(5)

x + 24 = 5x

Solution: D) 24 + x = 5x

Pachacha [2.7K]

Answer:

£216

Step-by-step explanation:

Cost = £6 per person
Teacher earns = 90% of total

Total number of people:

13 + 11 + 16 = £40

Total payment:

40*6= £240

Teacher earns in total per given week:

240*90/100 = £216

Millie drives from home to the Fixit Garage at a rate of 30 mph. She leaves her car and rides a bus back home. The bus makes the

Minchanka [31]

Answer:

D = 12 Miles from her house to Fixit.

Step-by-step explanation:

Speed =Distance travelled/ Time

Time =Distance travelled/ Speed

T = D / 30 The time it took her to drive to Fixit.

T = D / 20 The time it took her to ride the bus home.

D / 30 + D / 20 = 1 hour, solve for D,

Just use algebra to rearrange the terms so for s=1/2at^2 and solving for a we get 2s=at^2 so 2s/t^2=a
solving s=1/2at^2 for t gives 2s=at^2 which leads to 2s/a=t^2 so t=sqrt(2s/a)

filling in the numbers for 3 since a = 2s/t^2 we get a= (2(20.5m))/5s^2 =1.64m/s^2 the correct units in the answer indicate a possible correct answer since the units of acceleration are m/s^2.

4. using the value for a from question 3 and using 42.5 meters for s and solving for t we get sqrt((2s)/a) = sqrt((2*42.5m)/1.64m/s^2)= approximately 7.2s you can see the m's cancel and you are left s^2 as the units and the sqrt(s^2) = s so again the correct units indicate that 7.2s is probably correct. (These answers ARE correct though). checking the units gives a kinda quick assurance you are on the right path.
