Answer: The measurement of angle B is 34. The measurement of angle C is 108. The measurement of angle F is 72.
Answer:
I think its B
Step-by-step explanation: I'm not 100% sure
22m²
Area of parallelogram is simply the base length x height.
In this case, base length = 4m and height = 5.5m
hence,
Area = 4 x 5.5 = 22m²
each notebook costs $2.70
each pack of pencils costs $1.50
system of equations:
let p = pack of pencils
let n = notebook
3p + 5n = 18
4p + 4n = 16.8
I used the elimination method by multiplying the first equation by 4 and the second equation by -3
4(3p + 5n = 18) = 12p + 20n = 72
-3(4p + 4n = 16.8) = -12p -12n = -50.4
adding the new equations together you get: 8n = 21.6
n = 21.6/8
n = $2.70
solve for 'p':
3p + 5(2.7) = 18
3p + 13.5 = 18
3p = 4.5
p = $1.50
