That's all the answers and the work and i also put the PEMDAS method that i used.
Answer: 55 miles
Step-by-step explanation: Marcus goal is 80 miles for the week. he has already completed 25 miles of that goal so you would subtract 25 from 80 then you would find the miles still left
80-25=55
Solve simultaneously.
4x - y = 8
6x + y = 2
Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8
Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.
Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
You subtract 16 from 50
so 50-16=34
so your answer is 34 degree
Answer:
Which day was the weather forecast most accurate? Forecast vs Actual Temperature Day Degrees above (+) or below (–) forecast Monday +4 Tuesday –6 Wednesday +7 Thursday –2
(i) Monday
(ii) Tuesday
(iii) Wednesday
(iv) Thursday
Ans
(iv)Thursday
Step-by-step explanation:
Forecast for
Monday +4 Abs |+4| = 4
Tuesday –6 Abs |-6| = 6
Wednesday +7 Abs |+7| = 7
Thursday –2 Abs |-2| = 2
The most accurate is the day closest the temperature forecast is closest to observed temperature, which is
Thursday (-2)
