Answer:
QC - PB = 6
Step-by-step explanation:
Given PQ is parallel to BC then it divides the sides proportionally, that is
= = = , then
= ( cross- multiply )
8PB = 5QC → *
Given PB + QC = 26 , then
PB = 26 - QC
Substitute into *
8(26 - QC) = 5QC ← distribute left side
208 - 8QC = 5QC ( subtract 5QC from both sides )
208 - 13QC = 0 ( subtract 208 from both sides )
- 13QC = - 208 ( divide both sides by - 13 )
QC = 16
Thus PB = 26 - QC = 26 - 16 = 10
QC - PB = 16 - 10 = 6
Y=11x+4. formula: y=mx+b. insert the number of tickets where x is times 11 then add 4 to your total
Answer:
x+y≥80
10x+12y=≥$840
Step-by-step explanation:
The total number of drawings must be the number of portraits added to the number of landscapes which must be equal to 80 or more
The total amount that must be made is the total of the number of each type of drawings multiplied by their amount each which must be $840 or more
Answer:
y=-2x+6
Step-by-step explanation:
Using sine formula we have
8/sin60 = x/sin30
hence x= 8/√3 = 4.62
