a) because the denominators are the same add the numerators:
1 1/5 + 3 2/5 = 4 3/5
b) rewrite the fractions to have a common denominator:
1/2 = 3/6
1/3 = 2/6
Now subtract:
4 3/6 - 1 2/6 = 3 1/6
Answer:
answer is 4.15
Step-by-step explanation:
you just add the numbers its no different than a normal addition problem for the most part.
Answer:
z = 1, z = 9
Step-by-step explanation:
Given
z² + 9 = 10z ( subtract 10z from both sides )
z² - 10z + 9 = 0
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)
The factors are - 1 and - 9, since
- 1 × - 9 = 9 and - 1 - 9 = - 10, thus
(z - 1)(z - 9) = 0 ← in factored form
Equate each factor to zero and solve for z
z - 1 = 0 ⇒ z = 1
z - 9 = 0 ⇒ z = 9
Answer:
30%
Step-by-step explanation:
Product factor is an expression in where you multiply the same value digit SEVERAL times
Exponent is the expression in where you convert product factor expression into a more brief (shorter) expression
For example of product factor:
-> 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
As you can see, 3 is multiplied many times, that makes it more extended.
Now, let’s make this product factor shorter using exponent.
-> since 3 is multiplied 3 times the exponent expression is:
-> 3 3 in where 3 is the base and the other 3 is called exponent.
