Answer:
x= 5
Step-by-step explanation:
We are given;
- Base of the triangle as x
- Length of the leg is 4x-5
- An isosceles triangle has two equal legs and a base.
- The perimeter of the triangle is 35 (spelling mistake in the question)
To get the perimeter of a triangle we add the lengths of all sides of the triangle.
Therefore;
x + 4x-5 + 4x-5 = 35
9x - 10 = 35
9x = 45
x = 5
Thus, the value of x is 5
7.95 ÷ 1.06 = $7.50
This works as by dividing 7.95 by the percentage multiplier 1.06 it will give you the original amount.
An alternative method is to find out what 100% (7.95) is, then divide by 10 to find 10% and then divide by 10 again to find 1% and then multiply the 1% by 6 and subtracting the answer from 7.95.
Answer:
Explanation:
The standard form of an equation is expressed as y = mx+b
m is the slope
Given the equation x - y = 6
Rewrite in standard form;
-y = -x + 6
Multiply through by -1
-(-y) = -(-x) - 6
y = x - 6
Compare with the standard equation
mx = 1x
mx+b
m is the slope
