Answer: x=2
Step-by-step explanation:Solve for x by simplifying both sides of the equation then isolating the variable
Answer:
The correct answer is
Step-by-step explanation:
Method 1
We want to simplify,
The double negatives becomes positive,
We now add the whole number parts and the fractions separately
This will give us,
The least common denominator for the fractional parts is 9.
Method 2
We want to simplify,
The double negatives becomes positive,
We first convert the mixed numbers to improper fractions to obtain,
We carry out the multiplication in the numerator to get,
We add in the numerator to get,
The least common denominator is .
We convert back to mixed numbers to get,
Answer:
100 cm²
Step-by-step explanation:
Given that :
Length of prism = 20 cm
Height, h = 5cm
Width, w = 4 cm
The surface are of the side with clear material can be obtained by calculating the area of rectangule (front)
Area of rectangle = Length * height
Area = 20 * 5 = 100 cm²
Answer:
Simplify
The answer is:
Step-by-step explanation:
We have the expressions:
Now, we need simplify:
We need to replace each term by the expressions:
We need to remember the rule of signs:
With this in mind we solve the parentheses:
let's group common terms
We must add and subtract common terms:
The answer is:
Solve for x by simplifying both sides of the equation , then isolating the variable
your answer is x=3/4
