Answer:
11x - 21
Step-by-step explanation:
2(4x-3)-3(5-x)
Distributive property
= 8x - 6 - 15 + 3x
Combine like terms
= 11x - 21
Jason's part-time job pays him $105 a week
He got an amount of 105 dollars per week
Thhe cost price of the Dit bike = $900
The saving amount he had = $325
So, The amount he require more is the difference in the cost price of the bike to the saving amount
Require amount = 900-325
Require Amount = $575
Since he get the $105 per week
We need to find the number of weeks to get an amount of $575
So, divide the total required amount by the amount in one week he get
So, he neeed to wokr for 6 weeks to pay for the dirt bike
Answer : 6 weeks
The length of the measure of YZ is 80cm
<h3>Perpendicular lines</h3>
Perpendicular lines are lines that are at angle 90 degrees to each other. From the given diagram;
WX = 82cm
Required
Length. of YZ
Using the pythagoras theorem
YV = VZ = √41²-9²
YV = VZ = √1600
YV = VZ = 40
Since YZ = YV + VZ
YZ = 40cm + 40cm
YZ= 80cm
Hence the length of the measure of YZ is 80cm

Answer:
the third one
Step-by-step explanation:
You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference
Answer:
195.25
Step-by-step explanation:
Consider geometric series S(n) where initial term is a
So S(n)=a+ar^1+...ar^n
Factor out a
S(n)=a(1+r+r^2...+r^n)
Multiply by r
S(n)r=a(r+r^2+r^3...+r^n+r^n+1)
Subtract S(n) from S(n)r
Note that only 1 and rn^1 remain.
S(n)r-S(n)=a(r^n+1 -1)
Factor out S(n)
S(n)(r-1)=a(r^n+1 -1)
The formula now shows S(n)=a(r^n+1 -1)/(r-1)
Now use the formula for the problem
