Answer:
x=4
From the principles of isosceles triangles, two opposite sides are equal.
So,
4x+23=10x-1
solving the linear equation, we'd have x to be 4.
Answer:
Account balance is not proportional to the number of weeks.
Step-by-step explanation:
Initially Adrian's saving account balance was = $28
He deposits $15 in his account each week.
If we denote week with a variable 'x' then after 'x' weeks total amount in is account = $15x
So, total amount in his account after 'x' week will be;
y = 15x + 28
It's a linear equation representing total amount after 'x' weeks with a constant growth rate of 15 and initial amount 28.
In other words equation is in the form of y = mx +b.
This equation doesn't show the proportional relation because equation in the form of y = kx represents the relation of proportionality only.
Answer:
C.
Step-by-step explanation:
Answer:
Length of side a = 4.30 miles
Incomplete question:
The area of the regular polygon is 48 mi2. What is the length of side a? miles
Step-by-step explanation:
The number of sides of sides of the polygon is not given, so we will assume the polygon is an hexagon as shown in the attached image;
Given;
Area = 48 mi^2
Area of an hexagon using side a can be written as;
A = (3/2)√3×a^2
Making a the subject of formula
a = √(2/3√3 ×A)
Substituting the values
a = √(2/3√3 ×48)
a = √(32/√3)
a = 4.30 miles
