Answer
x=-5/2
Step-by-step explanation:
2×2+2x+1=0
4+2x+1=0(2×2=4)
4+1+2x=0
5+2x=0
2x=-5
x=-5/2
Step-by-step explanation:
Given
( 6x² - x + 8 ) - ( x² + 2)
= 6x² - x + 8 - x² - 2
= 5x² - x + 6
Answer:
7
Step-by-step explanation:
<u>Concepts:</u>
- Division: a system of distributing a collection of things into equal parts
- Fractions: #s that represent a part of a whole
- Dividing Fractions: dividing a fraction by another fraction = multiplying the fraction by the inverse (reciprocal) of the other one
- Inverse Operations: operations that are opposite of each other (e.g. inverse of addition is subtraction)
<u>Solving:</u>
1. First, let's set up the equation:
7/8 ÷ 1/8
2. We can get the reciprocal of 1/8 by doing the opposite of division; multiplication. 1/8 becomes 1 · 8, and that's equal to 8.
3. Now, since we know dividing a fraction by another one is exactly the same as multiplying the fraction by the reciprocal of the other, let's multiply 7/8 by the inverse of 1/8, which is 8.
7/8 · 8 = 56/8 = 7
Therefore, 7/8 divided by 1/8 is equal to <u>7</u>.
<h3>Number of minutes in 3/4 of an hour is :
</h3>
<h3>n = 3/4 × 60 = 45 minutes.
</h3>
<h3>Now, If it continues to rain at that rate for 15 more minutes :
</h3><h3>
</h3><h3>So, time taken = 45 + 15 min = 1 hour.
</h3><h3>
</h3><h3>Let, rain gauge is filled x fraction in 1 hour.
</h3>
<h3>So,
</h3>
<h3>Hence, this is the required solution.</h3>
