X less than or equal to (< with the line underneath) -3 or x>0
Answer:
-15x<=45 and 14x<=-42
x>=45/-15 and x<=-42/14
x>=-3 and x<=-3
so x=-3
Step-by-step explanation:
Set up a proportion having 120 over 3 = x over 8
cross multiply with 3x = 960
then divide by 3
the answer is 320 miles
Answer:
The measure of ∠D = (Q) = 28.81
Step-by-step explanation:
Tan(Q) = perpendicular/ base
In this case perpendicular is BC and base is DC
BC =25 DC = 45
Tan(Q) = BC/DC
Tan(Q) = 25/ 45
Tan(Q) = 5/ 9
(Q) = tan^ -1 (0.55)
(Q) = 28.81
Answer:
$637.5
Step-by-step explanation:
Given data
Cost of merchandise= $750
Discount= 15%
Let us find the amount of the discount
=15/100*750
=0.15*750
=$112.5
Hence the amount paid will be
=750-112.5
=$637.5
