Answer:
25
Step-by-step explanation:
Using the rules of BIDMAS, you first work out the calculation inside the bracket. y-z equals 25-20 which equals 5. then, you work out out the fraction. x=10 so 10/2 equals 5. Then, multiply the value inside the bracket (5) by the outside value(5). This equals 25
Start with
Simplify the left hand side by summing like terms (the one involving z):
Subtract 5z from both sides:
Subtract 7 from both sides
Divide both sides by 11:
Piper would make $557.5 in a week in which she made $2050 in sales
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, the given parameters are:
Guarantee fee = $250 per week
Commission = 15%
Let the total sales be x and the total amount be y
So, we have:
y = Guarantee fee + Commission * x
This gives
y = 250 + 15% * x
The total sales is $2050
This gives
y = 250 + 15% * 2050
Evaluate
y = 557.5
Hence, Piper would make $557.5 in a week in which she made $2050 in sales

Answer:
tan B = 12/5
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side/ adj side
tan B = 12/5
