Answer:
80
Step-by-step explanation:
16=20/100
y=3 x 100/20
y = 80%
Answer:
1. n = 2
2. -4 = r
Step-by-step explanation:
-n - 7n = -16
subtract the like terms, like terms are terms that have the same variable or power. Ex: n and 7n are like terms as they both have n, however 7n and 16 are not. x^2 and x are not like terms as they do not have the same power so:
-8n = -16
divide both sides by -8
n = 2
-20 = 3r + 2r
add like terms
-20 = 5r
divide 5 from both sides
-4 = r
Answer:
x = 72
Step-by-step explanation:
Start by multiplying 16 to both sides
16s on the left-hand cancel
we can simplify that expression
We Know, Area of Trapezium = (a+b)/2 * h
Where, a & b are parallel bases & h is height.
Here, we have a = 8, b = 18, h = 5
substitute them into the expression, as follows:
Area = (8+18)/2 * 5
A = 26/2 * 5
A = 13 * 5
A = 65
So, area would be 65 cm²
