Answer:
a
Step-by-step explanation:
Given:
let h be the high quality bean
let c be the cheaper bean
h + c = 160
6h + 3.25c = 160*4.97
6h + 3.25c = 795.20
h = 160 - c
6(160 - c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
-2.75c = 795.20 - 960
-2.75c = -164.80
c = -164.80 / -2.75
c = 59.92 or 60 lbs
h = 160 - c
h = 160 - 60
h = 100 lbs
Sarah should blend 60 lbs of cheap coffee bean and 100 lbs of high quality coffee bean.
Answer:
x = 7
Step-by-step explanation:
corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line
one is an obtuse and one is an acute angle in which sum up to 180°
(120°) + (7x + 11) = 180°
120° + 7x + 11 = 180°
131° + 7x = 180°
131° - 131° + 7x = 180° - 131°
7x = 49°
7x/7 = 49°/7
x = 7°
plug x in to check:
7(7) + 11 = 49 + 11 = 60
