The average is found by adding all the temperatures together, then dividing by the number of days.
Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.
The total for the first four days was : 56 + 60 + 79 + 70 = 265
The fifth day is 315 - 265 = 50 degrees.
Since m is equal to slope your m is -1/3 then you put the x after. Your b is the y intercept so your equation is y=-1/3x+7
Answer: m<PQT=60 and m<PQS=4x+14
m<PQS and m<SQT are same
m<PQT = m<PQS + m<SQT = m<PQS + m<PQS = 2m<PQS
m<PQT = 2m<PQS
So m<PQS =
Plug in the given information and solve for x
4x + 14 =
4x + 14 = 30 (subtract 14 on both sides)
4x = 16 (Divide by 4 on both sides)
x = 4
The value of x is 4
Answer:
2 and - 3
Step-by-step explanation:
I've attached my work...
- 4 + 20 / 8 -> 16/8 = 2
- 4 - 20 / 8 -> -24/8 = -3
Please give me feedback on my repsomse by commenting,
any way i can improve showing my work?
Hope it helps, let me know if you have questions !
Have a nice rest of your day :)
22 divided by -2 and you get -11 then 22 divided by -11 = -2
