Answer:
x=90
Step-by-step explanation:
First, it would help to make it so that the x's are not next to fractions. To do this, you can multiply all terms in the equation by 45. 45 is the closest common factor of 9 and 5, the denominators of the fractions. The answer would be;
20x+9x=2610
Then solve.
29x=2610
x=90

Answer:
32
Step-by-step explanation:
Imagine someone is trying to put tiles on a bathroom floor - this is the situation in this question. "tiles needed to fit across the length" is asking how many 25cm tiles can fit in the length of the bathroom, which is 8m.
To do this, we need to do some conversion.
8m to cm = 800cm
800 ÷ 25 = 32
This means 32 tiles are needed to fit across the length of the bathroom floor.

Answer:
a. Rational; b. rational
Step-by-step explanation:
A rational number is the quotient of two integers.
a. ⁴/₇ + ⁻¹/₃
![\begin{array}{rcl}\dfrac{4}{7} + \dfrac{-1}{3} & = & \dfrac{12}{21} + \dfrac{-7}{21} \\\\& = & \dfrac{5}{21}\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D%5Cdfrac%7B4%7D%7B7%7D%20%2B%20%5Cdfrac%7B-1%7D%7B3%7D%20%26%20%3D%20%26%20%5Cdfrac%7B12%7D%7B21%7D%20%2B%20%5Cdfrac%7B-7%7D%7B21%7D%20%5C%5C%5C%5C%26%20%3D%20%26%20%5Cdfrac%7B5%7D%7B21%7D%5C%5C%5Cend%7Barray%7D)
The solution is rational.
b. √4 ⅖
![\begin{array}{rcl}\sqrt{4} \, \dfrac{2}{5} & = & 2 \, \dfrac{2}{5}\\\\& = & \dfrac{22}{5}\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D%5Csqrt%7B4%7D%20%5C%2C%20%5Cdfrac%7B2%7D%7B5%7D%20%26%20%3D%20%26%202%20%5C%2C%20%5Cdfrac%7B2%7D%7B5%7D%5C%5C%5C%5C%26%20%3D%20%26%20%5Cdfrac%7B22%7D%7B5%7D%5C%5C%5Cend%7Barray%7D)
The solution is rational.
