Answer:
33% of a whole pizza
Step-by-step explanation:
2/3 of 100% = 66%
so 66% of the pizza has olives
she eat the half of that and the half from 66% is 33%
The answer is c(4) because if you multiply 4 three times it equals 64
Question
15 is the same as the product of 3 and a number. Which equation models this sentence?
15=3x
15=x-3
15=3+x
15=x divided by 3
Answer:
<h2>
15=3x</h2>
Step-by-step explanation:
15 = 3x
x = 15 : 3
x = 5
.........................
check
15 = 3 * 5
15 = 15
the answer is good
1) given x^4 + 95x^2 - 500
2) split in two factors with common factor term x^2: (x^2 + )(x^2 - )
3) find two numbers that add up 95 and their product is - 500:
=> 100*(-5) = - 500 and 100 - 5 = 95
=> (x^2 + 100)(x^2 - 5)
4) factor x^2 - 5 = (x + √5) (x - √5)
5) write the prime factors: (x^2 + 100) (x + √5) (x -√5)
6) find the solutions:
x^2 + 100 = 0 => not possible
x + √5 = 0 => x = - √5
x - √5 = 0 => x = √5
Answer: x = √5 and x = - √5
