Answer:
Really all you have to do is find X so what are your two number/fractions. So most likely you will divide. So get your two fractions or numbers and use the reciprocal.

Why does he need so much rice?
Step-by-step explanation:
![\frac{1}{2} * \frac{3}{3} = \frac{3}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%20%5Cfrac%7B3%7D%7B3%7D%20%3D%20%5Cfrac%7B3%7D%7B6%7D)
![\frac{1}{3} *\frac{2}{2} =\frac{2}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D%20%2A%5Cfrac%7B2%7D%7B2%7D%20%3D%5Cfrac%7B2%7D%7B6%7D)
Add the fractions
![\frac{3}{6} + \frac{2}{6} = \frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B6%7D%20%2B%20%5Cfrac%7B2%7D%7B6%7D%20%3D%20%5Cfrac%7B5%7D%7B6%7D)
Add the whole numbers
![41+21=62](https://tex.z-dn.net/?f=41%2B21%3D62)
Add fraction part with whole number part
![62+\frac{5}{6}\\\\= 62\frac{5}{6} =62.8333333333333333333333333333333333333333333333333333333333333333333333333](https://tex.z-dn.net/?f=62%2B%5Cfrac%7B5%7D%7B6%7D%5C%5C%5C%5C%3D%2062%5Cfrac%7B5%7D%7B6%7D%20%3D62.8333333333333333333333333333333333333333333333333333333333333333333333333)
It's D, y=0.078x + 29 works with all of the numbers
Answer:
(x - 3)(2x + 7)
Step-by-step explanation:
Assuming you require the expression factorised.
Given
2x² + x - 21
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 21 = - 42 and sum = + 1
The factors are - 6 and + 7
Use these factors to split the x- term
2x² - 6x + 7x - 21 ( factor the first/second and third/fourth terms )
= 2x( x - 3) + 7(x - 3) ← factor out (x - 3) from each term
= (x - 3)(2x + 7) ← in factored form
Step-by-step explanation:
All you have to do is
5-2(the number written on the x)
For example, the first given is - 1
5 - 2(-1)
The answer is 7
