8 0

First expand the brackets by multiplying each thing inside the brackets by 2:
4x−10=6x+4. then minus the 4x so there are only x 's on one side:
−10=2x+4. then minus the 4 so there are only numbers on one side and x 's on the other:
−14=2x. then divide by 2 to get the value of x

blsea [12.9K]

Frieda's weight is 1 Standard Deviation above the meanwhile her height is less than 1 Standard Deviation away from the mean. This means her height is closer to the mean than her weight.
As a result, we would say that her weight is definitely more unusual than her height because her weight is more standard deviations away from the mean.

Therefore,
in relative terms, it is correct to say that: Frieda's height is more unusual than her weight.

ad-work [718]

Answer:

Ashanti and Landry will for 7 hours to wash 56 cars

Step-by-step explanation:

* Lets explain how to solve the problem

- When to people work together to finish a job, we multiply the rate of

each by the time and add them,then equate the answer by the job

- Lets do that with Ashanti and Landry

- If Ashanti can wash 3 cars per hour

∴ The rate of Ashanti is 3 car per hour

- If Landry can wash 5 cars per hour

∴ The rate of Landry is 5 car per hour

- When they work together they will wash 56 cars

∵ They work together then they will work same amount of time

- Let the amount of time they will work is t

∵ Ashanti and Landry will work together for t hours to wash 56 cars

∴ 3t + 5t = 56

∴ 8t = 56

- Divide both sides by 8

∴ t = 7

∵ t represents the time they will work together

* Ashanti and Landry will for 7 hours to wash 56 cars
