The number of even positive integers less than a.b, i.e 90, is 45.

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtract, divide, and multiplying built-in functions.

Given that
a = 7 and b = 13

⇒ ab

Substitute the values of a and b in the above expression,

⇒ (7)(13)

⇒ 91

Since the number of even positive integers is less than

⇒ ab > even positive

⇒ 90 > even positive

since the even number less than a.b i.e. 91 is 90,
Here, 90 is the 45th number in the series of even positive numbers.


Thus, the number of even positive integer less than a.b, i.e 90, is 45

Solve for xxx. Write the smaller solution first, and the larger solution second.
____ [38]

Answer:

x=-5\text{ or }x=2

Step-by-step explanation:

We have been given an equation x^2+3x-10=0. We are asked to find the solutions of our given equation.

We will use splitting the middle term method to solve quadratic equation.

We will split middle term of our given equation into parts such that whose product is -10 and whose sum is 3.

We know that such two numbers are 5\text{ and }-2.

x^2+5x-2x-10=0

(x^2+5x)+(-2x-10)=0

x(x+5)-2(x+5)=0

(x+5)(x-2)=0

Using zero product property, we will get:

(x+5)=0\text{ or }(x-2)=0

x+5=0\text{ or }x-2=0

x=-5\text{ or }x=2

Therefore, the solutions for our given equation are x=-5\text{ or }x=2.

anastassius [24]
Difference in doughnuts = 50 - 40 = 10
Difference in money = 15 + 5 = 20

20 ÷ 10 = $2
Each doughnut costs $2

<em>Check:</em>
40 x 2 + 5 = $85
50 x 2 -15 = $85
Ravi has $85 at first.

Each doughnut costs $2
